    1986-01-01

    In response to increased public interest in cancer prevention and rapidly escalating health care costs, the National Cancer Institute supported the development of cancer prevention courses for health professionals. A multidisciplinary group of physicians, behavioral scientists, and educators developed, field-tested, revised, and evaluated a 12-module, 24-classroom-hour clinical preventive oncology course for primary care physicians. A rationale for education in cancer prevention is presented, the new clinical discipline of preventive oncology is defined, and contributory disciplines are identified. A curriculum based upon detailed learning objectives is described, short-term evaluation data are presented, and a methodology for incorporating a didactic course into a residency program is suggested. The positive reception given to this course by residents warrants optimism concerning application of a biopsychosocial or self-regulative model rather than the traditional biomedical one to clinical medicine and its teaching.

    Cancer prevention is a broad field that crosses many disciplines; therefore, educational efforts to enhance cancer prevention research focused on interdisciplinary approaches to the field are greatly needed. In order to hasten progress in cancer prevention research, the Cancer Prevention Internship Program (CPIP) at Purdue University was designed to develop and test an interdisciplinary curriculum for undergraduate and graduate students. The hypothesis was that course curriculum specific to introducing interdisciplinary concepts in cancer prevention would increase student interest in and ability to pursue advanced educational opportunities (e.g., graduate school, medical school). Preliminary results from the evaluation of the first year which included 10 undergraduate and 5 graduate students suggested that participation in CPIP is a positive professional development experience, leading to a significant increase in understanding of interdisciplinary research in cancer prevention. In its first year, the CPIP project has created a successful model for interdisciplinary education in cancer prevention research. PMID:21533583

    Solid organ transplant recipients are highly susceptible to skin cancer. The major driving factors are immunosuppressive medication and ultraviolet light. Appropriate sun protection markedly reduces the development of skin cancer. Skin cancer recognized at an early stage can reliably be cured, and fatal outcomes can be prevented. The aim of this work is to educate organ transplant recipients and health care professionals involved in their care, to increase awareness of skin cancer in this high-risk population and thus to optimize the long-term outcome of patients with skin cancer. Our newly developed website provides free access to various educational materials, including leaflets, presentations and interactive elements using edutainment.

    Full Text Available Background: Women’s beliefs are one of the main reasons for not undergoing Pap-test for cervical cancer prevention. Health education programs could help change these beliefs and motivate women to adopt a preventive health behavior.Objectives: This study aims to assess the modification in women’s beliefs and behavior about cervical cancer prevention after the implementation of a health education intervention.Methodology: A health education intervention for cervical cancer prevention was implemented to 300 women in two prefectures of southern Greece. The experimental group received a 120-minute health education intervention, based on the Health Beliefs Model (HBM including a lecture, discussion and leaflets. The hypotheses were a will this brief intervention change women’s beliefs (perceived susceptibility to cervical cancer, benefits and barriers ofundergoing the Pap-test? b will this change in beliefs sustain in six months follow-up period? and c will women undergo pap-test in six months period? The women filled in an anonymous questionnaire, based on the Health Belief Model (HBM, before, immediately after and six months after the program.Results: The health education intervention significantly modified women’s beliefs and behaviors towards pap-test. The greater changes in women’s beliefs were observed in their sense of susceptibility towards the disease and the benefits of prevention which were sustained or improved after six months. Perceived barriers to undergo the Paptest, pain, embarrassment, and worry for the results decreased immediately after the program but started relapsingin the six month follow up period. Moreover, 88.1% of the women answered that they had underwent a Pap-test during the following six months.Conclusions: This health education intervention modified women’s beliefs and behavior about cervical cancer prevention. Short, low cost, health education interventions for breast cancer prevention to women can be

    Full Text Available Background: Prevalence rates in breast cancer have now reached epidemic levels. One of the main reasons behind onset of breast cancer is poor preventive beliefs and behavior of women towards cancer prevention. We examined the effectiveness of health education intervention in two communities of South Greece.Objective: The study investigates the effectiveness of a brief health education intervention on women’s beliefs and behaviour changes concerning breast cancer prevention.Methodology: A 90-minute, one-off encounter, health education study was designed for 300 women from Peloponissos, South Greece. A Health Belief Model questionnaire, was used before the intervention, immediately after and 6-months after the intervention.Results: Despite certain perception-related barriers (embarrassment, anxiety, ect women’s overall beliefs towards breast cancer prevention (perceived susceptibility, perceived benefits and perceived barriers changed positively after the health education intervention and this change was sustained at 6-month follow up. However, specific barriers (embarrassment, fear of pain, anxiety when anticipating tests’ results were not maintained at the same level of post-intervention during the same follow up. During the follow up period, women performed breast self-examination every month (73% and 55.10% had breast examination by a clinician and underwent a mammography.Conclusions: Short, low cost, health education interventions for breast cancer prevention to women can be effective in changing beliefs and behaviour. Tailored interventions are necessary to overcome relapsing of specific barriers. Emphasis should be given on the importance of doctor/nurse role in breast screening.

    As the minority population increases in the United States, the incidence of skin cancer has important public health consequences, including poor skin cancer outcomes, in part because of late-stage diagnosis. Therefore, it is important to identify obstacles in skin cancer prevention in these communities. To characterize skin cancer prevention and education needs in uninsured, minority, and immigrant communities in South Florida. At a large free medical clinic in Florida, a convenience sample of people completed a 23-question survey in English, Spanish, or Haitian Creole assessing their skin cancer risk perception, knowledge, sun protective behaviors and barriers, and desirable outreach methods. All participants were uninsured and living at least 200% below the federal poverty level. Participants were adults recruited from the general waiting room who understood 1 of the 3 languages and were not present for a scheduled dermatology visit. The survey used Likert-type scales, true or false, and yes or no questions. Data were analyzed with SPSS IBM statistical software (version 22) using 1-way analysis of variance, χ2 tests, and Pearson correlations. Among the 219 people invited, 206 participants (mean [SD] age, 43 [13.2] years) completed the survey; 75% of respondents were women who usually worked indoors. Almost a quarter (49 [24.5%) had never heard of skin cancer or melanoma. Nearly half (89 [44.3%]) had never conducted a self-skin examination. One in 5 (41 [20.7%]) believed that people with dark skin cannot get skin cancer. Three quarters (156 [75.7%]) of respondents fell into the "low/inconsistent" sun protective behavior category. Barriers to sun-protective behaviors were "using sun protection is too hot" (75 participants [39.3%]) and "I forget." (72 [37.7%]). More than 85% (175 [87.9%]) wanted to learn more about how to prevent skin cancer. Watching a video (37.3%) and text messaging (30.8%) were identified as the most popular outreach methods. Important barriers

    The Forsyth County Cervical Cancer Prevention Project (FCP) is a community-based health education project funded by the National Cancer Institute. The target population includes around 25 000 black women age 18 and older who reside in Forsyth County, North Carolina. The overall goal of the program is to prevent mortality from cervical cancer by promoting Pap smears and return for follow-up care when needed. Based on the principles of social marketing, a plan to reach the target population with mass media educational messages through electronic and print channels was developed. Guided by marketing objectives, the target population was divided into relatively discrete segments. The segments included church attenders, patients in waiting rooms of public and selected health providers, female students at local colleges, shoppers, viewers of radio and television, newspaper readers, and business owners and managers. Introduction of the program was based on strategies developed for reaching the target population in each segment with television, radio and print mass media messages. Qualitative assessment of the mass media developed by the program indicated that all forms of communication helped to increase awareness of the program.

    Full Text Available Cervical cancer is a serious health problem due to high mortality rates that are associated with it. The high incidence rates can be explained by women and their families’ ignorance about this disease. In fact, cervical cancer can be diagnosed early and, if detected on time, the likelihood of cure is high. Latin America is considered at high risk for cervical cancer. More specifically, cervical cancer in Mexico ranks second in incidence after breast cancer, in spite of having a screening program for over 20 years, which has only been able to prevent 13% of potentially preventable cases. The purpose of this analysis is to once again address the importance cervical cancer, to offer a general overview of the nature of this disease, but most of all, to underscore the relevance of education as a means of detection and prevention.

    Despite advances in oncology care, infections from both community and healthcare settings remain a major cause of hospitalization and death among patients with cancer receiving chemotherapy. Neutropenia (low white blood cell count) is a common and potentially dangerous side effect in patients receiving chemotherapy treatments and may lead to higher risk of infection. Preventing infection during treatment can result in significant decreases in morbidity and mortality for patients with cancer. As part of the Centers for Disease Control and Prevention's (CDC's) Preventing Infections in Cancer Patients public health campaign, a public-private partnership was formed between the CDC Foundation and Amgen, Inc. The CDC's Division of Cancer Prevention and Control developed and launched an interactive website, www.PreventCancerInfections.org, designed for patients with cancer undergoing chemotherapy. The site encourages patients to complete a risk assessment for developing neutropenia during their treatment. After completing the assessment, patients receive information about how to lower the risk for infection and keep themselves healthy while receiving chemotherapy.

    Cervical cancer is one of the leading causes of cancer and cancer-related deaths among women worldwide. More than 85% of cases and deaths occur in the developing world where the availability of effective screening is limited. In this issue of the journal, Pierce and colleagues (beginning on page 1273) describe a novel technique using a high-resolution microendoscope (HRME) to diagnose cervical dysplasia. This perspective reviews the limitations of existing cervical cancer screening methods currently in use in low-resource settings and the potential for HRME imaging to contribute to cervical cancer prevention in the developing world.

    This article describes the use of survey research in collaboration with the African American urban community of Georgetown, Jackson, Mississippi to identify and understand prostate cancer knowledge, resource utilization, and health education strategies considered most effective in reaching the community with prostate cancer prevention messages. The study revealed profound needs in disease identification and resources awareness and utilization. Barriers to utilization were identified by participants to include lack of self-efficacy, low self-esteem, lack of trust in the health care system, limited knowledge of prostate pathology, and limited ability to pay. Participants' recommended strategies for reaching the community with prostate cancer education include traditional and nontraditional strategies. The list of recommendations exclude modern-day outlets such as handheld devices, Twitter, Facebook, blogs, wikis, and other Internet-based outlets. The findings provide a road map for program development and an intervention research agenda custom-tailored to the Georgetown community of Jackson, Mississippi.

    Introduction Prevention programs have not achieved the expected results in preventing mortality from breast and cervical cancer in Mexico. Therefore, we propose a complementary strategy. Methodology An educational strategy for high school students in Mexico (2011–2013) was designed (longitudinal design, two measurements and a single intervention). The postintervention assessment included: 1) knowledge acquired by students about cancer prevention and 2) The performance of the student as a health promoter in their household. The strategy was based on analysis of cases and developed in three sessions. An assessment tool was designed and validated (Test–Retest). The levels of knowledge according to the qualifications expected by chance were determined. Wilcoxon test compared results before and after intervention. Results An assessment instrument with 0.80 reliability was obtained. 831 high school students were analyzed. Wilcoxon rank-sum test showed a significant learning after the intervention (Z = − 2.64, p = 0.008) with improvement of levels of knowledge in a 154.5%. 49% of students had a good performance as health promoters. Conclusions The learning in preventive measures is important to sensitize individuals to prevention campaigns against cancer. This strategy proved to improve the level of knowledge of students in an easy and affordable way. PMID:26844079

    Full Text Available Objectives: Many urological cancers like prostate and bladder have protracted course and maybe ideal for chemoprevention strategies. This article reviews the biol-ogy, epidemiology and possible preventive strategies for the various urological cancers. Methods: The author reviewed the relevant articles published in the last 20 years and studied the biology of the various urological cancers. An attempt is made to identify the various dietary, nutritional and occupation-related factors implicated in the onset and progression of various urological cancers. The various interventions and clinical trial results are described to prove the relevance of these factors. Results: Epidemiological reports provide the strongest evidence of protective role for dietary agents in cancer of prostate, bladder and kidney. Cancers of prostate and blad-der are uniquely suitable for chemopreventive strategies. For prostate cancer strong evidence exists for a preven-tive effect of reduced fat intake, vitamin E, selenium, lycopene and soya proteins. Vitamin A administration shows a strong inverse relation to bladder cancer. Better prevention is seen with combination of high doses of vita-mins A, C, E and B6. High-energy intake is related to the higher incidence of renal cell carcinoma (RCC. While vitamins D and E supplementation has resulted in lower incidence of RCC. Conclusions: Numerous studies implicate dietary and nutritional factors in the onset and progression of various urological cancers. Hence, it is possible that bioactive compounds (anti-oxidants like vits. A, D, C, and E, min-erals like selenium and carotenoids like lycopene along with reduction of animal fat in diet can be a part of pre-ventive strategies for various urological cancers.

We found that PDA occurs quite frequently but is usually diagnosed too late, at its advanced stage. Screening for PDA is not very well defined except in subgroups of high-risk individuals with genetic disorders or with chronic pancreatitis. We present convincing, probable, and suggestive risk factors associated with pancreatic cancer, many of which are modifiable and should be introduced and implemented in our society.

    The Jade Ribbon Campaign (JRC) is a culturally targeted, community-based outreach program to promote the prevention, early detection, and management of chronic hepatitis B virus (HBV) infection and liver cancer among Asian Americans. In 2001, 476 Chinese American adults from the San Francisco Bay Area attended an HBV screening clinic and educational seminar. The prevalence of chronic HBV infection was 13%; only 8% of participants showed serologic evidence of protective antibody from prior vaccination. Participants reported low preventive action before the clinic, but after one year, 67% of those with chronic HBV infection had consulted a physician for liver cancer screening, and 78% of all participants had encouraged family members to be tested for HBV. The increase in HBV awareness, screening, and physician follow-up suggests that culturally aligned interventions similar to the JRC may help reduce the disproportionate burden of disease to chronic HBV infection among Asian Americans.

  19. Selenium for preventing cancer

    Full Text Available BACKGROUND: Selenium is a trace element essential to humans. Higher selenium exposure and selenium supplements have been suggested to protect against several types of cancers. OBJECTIVE: Two research questions were addressed in this review: What is the evidence for: 1. an aetiological relationship between selenium exposure and cancer risk in women and men?; 2. the efficacy of selenium supplementation for cancer prevention in women and men? SEARCH STRATEGY: We searched electronic databases and bibliographies of reviews and included publications. SELECTION CRITERIA: We included prospective observational studies to answer research question (a and randomised controlled trials (RCTs to answer research question (b. DATA COLLECTION AND ANALYSIS: We conducted random effects meta-analyses of epidemiological data when five or more studies were retrieved for a specific outcome. We made a narrative summary of data from RCTs. MAIN RESULTS: We included 49 prospective observational studies and six RCTs. In epidemiologic data, we found a reduced cancer incidence (summary odds ratio, OR, 0.69; 95% confidence interval, CI, 0.53 to 0.91 and mortality (OR 0.55, 95% CI 0.36 to 0.83 with higher selenium exposure. Cancer risk was more pronouncedly reduced in men (incidence: OR 0.66, 95% CI 0.42 to 1.05 than in women (incidence: OR 0.90, 95% CI 0.45 to 1.77. These findings have potential limitations due to study design, quality and heterogeneity of the data, which complicated the interpretation of the summary statistics. The RCTs found no protective efficacy of selenium yeast supplementation against non-melanoma skin cancer or L-selenomethionine supplementation against prostate cancer. Study results for the prevention of liver cancer with selenium supplements were inconsistent and studies had an unclear risk of bias. The results of the Nutritional Prevention of Cancer Trial (NPCT and SELECT raised concerns about possible harmful effects of selenium supplements. AUTHORS

    Reduction in the incidence of cancer can be achieved through appropriate health behaviors. We hypothesized that education would improve knowledge of cancer prevention, and this, in turn, will affect and individual's readiness to modify lifestyle. The aim of this study was to assess the impact of cancer prevention education on adopting and preserving prohealth attitudes among high school students in Poland. Research participants were 307 high school students varying by gender, place of residence, parents' education, and type of school education. Participants were divided into five groups, of which four were educated using different methods according to classification methods based on the concept of multilateral learning. The fifth (control) group was not educated. The effects of education were assessed 1 month and 1 year after education. General knowledge about cancer and healthy lifestyle level before education was low. After education, both increased compared with the control group. There was a clear relationship between level of knowledge and readiness to adopt and healthy attitudes and behavior. The most effective method of education was a discussion and a lecture by means of teaching complex. Education significantly improved generally low knowledge about cancer and healthy lifestyle in high school students. This indicates the urgent need to implement such educational programs.

    Background This review is an update of the first Cochrane publication on selenium for preventing cancer (Dennert 2011). Selenium is a metalloid with both nutritional and toxicological properties. Higher selenium exposure and selenium supplements have been suggested to protect against several types of cancers. Objectives Two research questions were addressed in this review: What is the evidence for: an aetiological relation between selenium exposure and cancer risk in humans? andthe efficacy of selenium supplementation for cancer prevention in humans? Search methods We conducted electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL, 2013, Issue 1), MEDLINE (Ovid, 1966 to February 2013 week 1), EMBASE (1980 to 2013 week 6), CancerLit (February 2004) and CCMed (February 2011). As MEDLINE now includes the journals indexed in CancerLit, no further searches were conducted in this database after 2004. Selection criteria We included prospective observational studies (cohort studies including sub-cohort controlled studies and nested case-control studies) and randomised controlled trials (RCTs) with healthy adult participants (18 years of age and older). Data collection and analysis For observational studies, we conducted random effects meta-analyses when five or more studies were retrieved for a specific outcome. For RCTs, we performed random effects meta-analyses when two or more studies were available. The risk of bias in observational studies was assessed using forms adapted from the Newcastle-Ottawa Quality Assessment Scale for cohort and case-control studies; the criteria specified in the Cochrane Handbook for Systematic Reviews of Interventions were used to evaluate the risk of bias in RCTs. Main results We included 55 prospective observational studies (including more than 1,100,000 participants) and eight RCTs (with a total of 44,743 participants). For the observational studies, we found lower cancer incidence (summary odds ratio (OR) 0

    The incidence of cervical cancer has hopefully been dropping down in our industrialized countries since the introduction of both primary and secondary prevention. Nevertheless, it is still lethal in one out of two affected women though the introduction of cytological screening has dramatically reduced the mortality. Progressive diffusion of anti-HPV vaccination, the broadening of the viral types concerned, its association with existing screening measures and finally the introduction of viral detection as a screening tool must optimize the results already obtained.

    Coughlin, Steven; Thind, Herpreet; Liu, Benyuan; Champagne, Nicole; Jacobs, Molly; Massey, Rachael I

    2016-05-30

    Rapid developments in technology have encouraged the use of mobile phones in smoking cessation, promoting healthy diet, nutrition, and physical activity, sun safety, and cancer screening. Although many apps relating to the prevention of cancer and other chronic diseases are available from major mobile phone platforms, relatively few have been tested in research studies to determine their efficacy. In this paper, we discuss issues related to the development and testing of new apps for preventing cancer through smoking cessation, sun safety, and other healthy behaviors, including key methodologic issues and outstanding challenges. An exploratory literature review was conducted using bibliographic searches in PubMed and CINAHL with relevant search terms (eg, smartphones, smoking cessation, cancer prevention, cancer screening, and carcinogens) to identify papers published in English through October 2015. Only 4 randomized controlled trials of the use of mobile phone apps for smoking cessation and 2 trials of apps for sun safety were identified, indicating that it is premature to conduct a systematic search and meta-analysis of the published literature on this topic. Future studies should utilize randomized controlled trial research designs, larger sample sizes, and longer study periods to better establish the cancer prevention and control capabilities of mobile phone apps. In developing new and refined apps for cancer prevention and control, both health literacy and eHealth literacy should be taken into account. There is a need for culturally appropriate, tailored health messages to increase knowledge and awareness of health behaviors such as smoking cessation, cancer screening, and sun safety. Mobile phone apps are likely to be a useful and low-cost intervention for preventing cancer through behavioral changes.

    Full Text Available Introduction: Preventive behaviors such as screening tests have an important role in prevention and control of breast cancer. Therefore, this study aimed to determine the effect of educational programs on preventive behaviors of breast cancer based on the health belief model among female teachers of guidance schools in Zahedan city. Materials and Methods: This quasi-experimental study was performed on 240 female teachers from (120 participants in each of the control and intervention groups Zahedan guidance schools. The data-gathering tool was a multipart questionnaire containing demographic variables, knowledge and health belief model structures. An educational program was performed based on the health belief model in five sessions through lectures, training videos, question and answer session for participants in the intervention group. Questionnaires were filled before and two months after the intervention in the two groups. Data was analyzed by independent T-test, chi-square and multiple linear regressions using SPSS-15 software. Results: There was no meaningful difference in the mean scores of knowledge, health belief model constructs, and performance between the two groups before the educational intervention, but the mean scores of variables increased significantly after the intervention (P< 0.05. Conclusion: The health belief model was effective to promote preventive behaviors. Hence, educational interventions with an emphasis on raising awareness, change in beliefs and improving self-efficacy regarding breast cancer are recommended

  3. Cancer prevention in the Asia Pacific region.

    Yoo, Keun-Young

    2010-01-01

    Cancer incidences as well as the most prevalent cancer types vary greatly across Asian countries since people have differing health behaviors as well as lifestyle factors related to cancer risk. Countries have varying systems of government organization, laws, resources, facilities, and management strategies for addressing the cancer burden. Examples such as Korea and Japan with existing national cancer control programs need to focus on early screening and detection and quality of screening methods. If screening and detection increase to cover more than 50% of the target population, survival rate increases and thus the number of cancer patients detected increases resulting in higher medical cost. Thus, expansion of cancer screening, in addition to smoking prevention, immunization increase, and diet control awareness, are needed for cancer prevention strategies. Countries such as Thailand, China, Malaysia, and Turkey need to begin organized efforts to reduce cancer deaths through state-wide cancer screening programs. Strategies focused on increasing survival among cancer patients are also needed. In addition, government organizations and law regulations need to be in place as the first step towards cancer prevention. For the countries such as Nepal, Pakistan, Mongolia, and Iraq which do not have any cancer-related organizations in place, the first step that is needed is to raise public awareness about cancer; a public awareness campaign is the number one priority and should begin immediately. The easiest and most feasible step at this point is dissemination of cancer education materials during school health education and physical health screening. This must be started immediately because we need to avoid the development of existing cancers where patients will need to seek specialized cancer treatment facilities that are non-existent in these regions. In addition, hospitals need to take a step further and start undergoing registration of cancer prevalence and

  4. Cancer prevention in Africa: a review of the literature.

    Science.gov (United States)

    Busolo, David S; Woodgate, Roberta L

    2015-06-01

    Cancer is an emerging crisis in Africa. Cancer was the seventh leading cause of death in 2004. If not controlled, cancer incidence in Africa is expected to reach 1.28 million cases annually and claim 970,000 lives yearly by 2030. This paper presents a review of the literature on current cancer prevention approaches in Africa, and consists of cancer prevention studies conducted in African countries (e.g. South Africa and Nigeria) from PubMed, Scopus, and CINAHL databases. Common female cancers in Africa are breast and cervical cancer while prostate cancer is the most common neoplasm among African males. Other common cancers are liver, colorectal, and non-Hodgkin's lymphoma. Mortality related to these cancers comes as a result of delays in screening and treatment, unfamiliarity with cancer and cancer prevention, inaccessibility and unaffordability of care, and inefficiency of healthcare systems. Cancer prevention efforts are deficient because many governments lack cancer prevention and control policies. Also contributing to the lack of cancer prevention and control policies are low levels of awareness, scarce human and financial resources, and inadequacy of cancer registries. Overall, governments grapple with limited funds and competing healthcare priorities. As cancer continues to increase in Africa, the need for rigorous interdisciplinary research on cancer etiology and monitoring in Africa has never been timelier. Cost-effective cancer prevention programs, coordination of donor funding, advocacy, and education should be aggressively pursued. The call for more collaborative approaches in research and policy is urgently needed.

  5. Diet and Pancreatic Cancer Prevention.

    2015-11-23

    Pancreatic cancer is without any doubt the malignancy with the poorest prognosis and the lowest survival rate. This highly aggressive disease is rarely diagnosed at an early stage and difficult to treat due to its resistance to radiotherapy and chemotherapy. Therefore, there is an urgent need to clarify the causes responsible for pancreatic cancer and to identify preventive strategies to reduce its incidence in the population. Some circumstances, such as smoking habits, being overweight and diabetes, have been identified as potentially predisposing factors to pancreatic cancer, suggesting that diet might play a role. A diet low in fat and sugars, together with a healthy lifestyle, regular exercise, weight reduction and not smoking, may contribute to prevent pancreatic cancer and many other cancer types. In addition, increasing evidence suggests that some food may have chemo preventive properties. Indeed, a high dietary intake of fresh fruit and vegetables has been shown to reduce the risk of developing pancreatic cancer, and recent epidemiological studies have associated nut consumption with a protective effect against it. Therefore, diet could have an impact on the development of pancreatic cancer and further investigations are needed to assess the potential chemo preventive role of specific foods against this disease. This review summarizes the key evidence for the role of dietary habits and their effect on pancreatic cancer and focuses on possible mechanisms for the association between diet and risk of pancreatic cancer.

    Breast cancer incidence rates, pattern of presentation and survival rates vary worldwide. High incidence, advanced stage disease presentation and low survival rates have been reported from Pakistan. Lack of awareness and screening facilities along with poor socioeconomic status are the main causes. A survey based upon multiple choice questionnaires was conducted during an awareness campaign in women educational institutions of Lahore, to assess the baseline knowledge, attitude towards breast self examination (BSE), clinical breast examination (CBE) and source of information used by them. 1155 filled questionnaires were analyzed by SPSS version 12. The majority (83.7%) of the respondents were 10 and 31.5% had education. Only 27% had "good" while 14% had "poor" and 59% had "fair" knowledge scores about breast cancer. Television was the most commonly cited source of information but was associated with lower knowledge score. The knowledge scores and practice of BSE had a positive association with education level. The respondents had better knowledge of life time risk and association of early diagnosis with better chances of cure, but worse knowledge of risk factors as compared to women in educational institutions of other countries. Generally the respondents of present study had low level of knowledge of breast cancer. Properly designed awareness campaign on television and in educational institutions can be effective to raise the knowledge level, the best long term strategy for this purpose.

    Extracts of green tea and green tea polyphenols have exhibited inhibitory effects against the formation and development of tumors at different organ sites in animals. These include animal models for skin, lung, oral cavity, esophagus, stomach, intestine, colon, liver, pancreas, bladder, mammary gland, and prostate cancers. In addition to suppressing cell proliferation, promoting apoptosis, and modulating signaling transduction, green tea polyphenols, especially (-)-epigallocatechin-3-gallate, also inhibit cell invasion, angiogenesis, and metastasis. This article reviews data on the cancer preventive activities of green tea polyphenols, possible mechanisms involved, and the relationship between green tea consumption and human cancer risk.

    This study was conducted in order to examine the effects of community-based education on cervical cancer prevention in relation to South Korean mothers' knowledge about the Papanicolau (Pap) test and human papillomavirus, self-confidence in communication with their daughters, and health-related beliefs about their daughters. A quasi-experimental pre-post design was used. For the experimental group, face-to-face education was administered to 35 participants for 60 min. For the control group, 35 participants were taught by using standardized materials for 20 min. The experimental group showed a significant increase in Pap test knowledge, cervical cancer knowledge, and self-confidence in communication with their daughters, compared to the control group. In the post-test, the mothers in the experimental group also perceived cervical cancer as more threatening, their daughter as more susceptible to cervical cancer, Pap tests as being recommended for their daughters, and they showed a significant increase in their self-efficacy of recommending the Pap test to their daughter. Community-based education for mothers is effective in increasing their human papillomavirus knowledge, Pap test knowledge, improving their confidence in communication with their daughters, and in some of the health-related beliefs regarding their daughters. © 2017 Japan Academy of Nursing Science.

    Although only a relatively small proportion of cancer is attributable to occupational exposure to carcinogenic agents, the estimated number of deaths due to occupational cancer is high when compared to other deaths due to work-related ill health and injury. However, risk from occupational exposure to carcinogens can be minimised through proportionate but effective risk management. The Health and Safety Executive (HSE) is the regulator of workplace health and safety in Great Britain. As part of its aim to reduce ill health arising from failures to control properly exposure to hazards at work, HSE commissioned the research presented elsewhere in this supplement to enable it to identify priorities for preventing occupational cancer. The research has shown that occupational cancer remains a key health issue and that low-level exposure of a large number of workers to carcinogens is important. The finding that a small number of carcinogens have been responsible for the majority of the burden of occupational cancer provides key evidence in the development of priorities for significant reduction of occupational cancer. Although the research presented in this supplement reflects the consequences of past exposures to carcinogens, occupational cancer remains a problem. The potential for exposure to the agents considered in this research is still present in the workplace and the findings are relevant to prevention of future disease. In this article, the principle approaches for risk reduction are described. It provides supporting information on some of the initiatives already being undertaken, or those being put in place, to reduce occupational cancer in Great Britain. The need also for systematic collection of exposure information and the importance of raising awareness and changing behaviours are discussed.

  5. Primary Prevention of Colorectal Cancer

    Chan, Andrew T.; Giovannucci, Edward L.

    2010-01-01

    Colorectal cancer has been strongly associated with a Western lifestyle. In the past several decades, much has been learned about the dietary, lifestyle, and medication risk factors for this malignancy. Although there is controversy about the role of specific nutritional factors, consideration of the dietary pattern as a whole appears useful for formulating recommendations. For example, several studies have shown that high intake of red and processed meats, highly refined grains and starches, and sugars is related to increased risk of colorectal cancer. Replacing these factors with poultry, fish, and plant sources as the primary source of protein; unsaturated fats as the primary source of fat; and unrefined grains, legumes and fruits as the primary source of carbohydrates is likely to lower risk of colorectal cancer. Although a role for supplements, including vitamin D, folate, and vitamin B6, remains uncertain, calcium supplementation is likely to be at least modestly beneficial. With respect to lifestyle, compelling evidence indicates that avoidance of smoking and heavy alcohol use, prevention of weight gain, and the maintenance of a reasonable level of physical activity are associated with markedly lower risks of colorectal cancer. Medications such as aspirin and non-steroidal anti-inflammatory drugs and post-menopausal hormones for women are associated with significant reductions in colorectal cancer risk, though their utility is affected by associated risks. Taken together, modifications in diet and lifestyle should substantially reduce the risk of colorectal cancer and could complement screening in reducing colorectal cancer incidence. PMID:20420944

    The successful demonstration that the selective estrogen receptor modulators (SERMs) tamoxifen and raloxifene reduce the risk of breast cancer has stimulated great interest in using drugs to prevent breast cancer in high-risk women. In addition, recent results from breast cancer treatment trials suggest that aromatase inhibitors may be even more effective at preventing breast cancer than are SERMs. However, while SERMs and aromatase inhibitors do prevent the development of many estrogen-recep...

    1997-01-01

    Full Text Available The potential use of vaccines for the human papillomavirus (HPV in the prevention and treatment of cervical cancer is a possibility in the near future. Close to 20 genotypes of HPV, of the 75 that have been identified, infect the femine genital tract, but four subtypes (16, 18, 31 and 45 have been associated in close to 80% of cervical cancers. this article proposes that in order to design an effective prophylactic vaccine against HPV infection, an adequate immune response should be guaranteed through four goals; a activation of antigens present in the cell; b overcoming the host response and viral genetic variability in the T cell response; c generation of high levels of T and B memory cells; and d persistence of antigens.

    The aim of this study was to evaluate the effects of an educational intervention on breast self-examination, cancer prevention-related knowledge, practices, and behavior change in scholars from a low-income area in Bogota, Colombia. Uncontrolled trial was conducted in 155 scholars. Two educational sessions, 90 min each, were carried out in March 2015 according to the Colombian guidelines for educational communication in the framework of cancer control. All participants completed a self-reported questionnaire at pre- and post-intervention, as well as 1, 3, and 6 months after the intervention. Breast self-examination was practiced by 78.1% of the scholars, and the overall knowledge of breast cancer risk factors was poor. The educational intervention resulted in significant improvements on breast self-examination practice, the knowledge of the technique, and the knowledge of the main risk factors for breast cancer as well as the practice of physical activity and vegetable intake at 6 months follow-up. An educational intervention according to the Colombian guidelines for educational communication in the framework of cancer control improved the practice of breast self-examination, cancer prevention-related knowledge, as well as the practice of physical activity and vegetable consumption in scholars from a low-income area in Bogota, Colombia. Further randomized controlled studies are warranted.

    Full Text Available OBJECTIVES: To understand knowledge about, and acceptability of, cervical cancer screening and HPV vaccines among medical students; and to explore potential factors that influence their acceptability in China. METHODS: We conducted a survey among medical students at six universities across southwest China using a 58-item questionnaire regarding knowledge and perceptions of HPV, cervical cancer, and HPV vaccines. RESULTS: We surveyed 1878 medical students with a mean age of 20.8 years (standard deviation: 1.3 years. Of these, 48.8% and 80.1% believed cervical cancer can be prevented by HPV vaccines and screening respectively, while 60.2% and 71.2% would like to receive or recommend HPV vaccines and screening. 35.4% thought HPV vaccines ought to be given to adolescents aged 13-18 years. 32% stated that women should start to undergo screening from the age of 25. 49.2% felt that women should receive screening every year. Concern about side effects (38.3% and 39.8%, and inadequate information (42.4% and 35.0% were the most cited barriers to receiving or recommending HPV vaccination and cervical cancer screening.

    Prostate cancer is the most common malignancy in men in the United States. Surgery or radiation are sometimes unsatisfactory treatments because of the complications such as incontinence or erectile dysfunction. Selenium was found to be effective to prevent prostate cancer in the Nutritional Prevention of Cancer Trial (NPC), which motivated two other clinical trials: the Selenium and Vitamin E Cancer Prevention Trial (SELECT) and a Phase III trial of selenium to prevent prostate cancer in men with high-grade prostatic intraepithelial neoplasia. However, these two trials failed to confirm the results of the NPC trial and indicated that the selenium may not be preventive of prostate cancer. In this article we review the three clinical trials and discuss some different points which might be potential factors underlying variation in results obtained.

    2015-12-01

    "War on cancer" was declared through the National Cancer Act by President Richard Nixon in 1971, but cancer statistics from the American Cancer Society and other sources indicated the failure of this war, suggesting instead focus on the message that a "prevention strategy" might be much more effective than cancer treatment. While cancer statistics notoriously showed sharp increases in incidence as well as in mortality concurrent with economic growth in Asia, fortunately Asian countries benefit from plentiful resources of natural compounds, which can prevent cancer. Just like cancer chemotherapeutics targeted to kill cancer cells in Western countries, natural agents activating molecular mechanisms for cancer prevention, reversion of premalignant tumors, and even ablation of cancer stem cells, are very abundant in Asia. Currently, these natural agents are under very active investigations targeting the hallmarks of cancer prevention, including selective induction of apoptosis in cancer cells, suppression of growth factors or their signaling, suppression of cell proliferation and of cancer-promoting angiogenesis, induction of mesenchymal-epithelial transition, and disruption of the tumor microenvironment, developing promising cancer preventive agents. However, Asia is the most populous continent in the world and some Asian countries do not have the resources to implement cancer screening programs for early detection or treatment. In addition, despite the excellent cancer preventive screening strategies in some Asian countries, well-designed clinical trials for cancer prevention are somewhat delayed compared to Western countries.

    Further understanding of educators' views of eating disorder prevention can further engage them in this effort. No previous studies of educators have used acceptability methodology or compared eating disorder prevention to other prevention efforts. Educators (n = 135) rated the acceptability of five sample programs and provided their opinions about eating disorder and other prevention programs. The results indicated primarily psychoeducational and general well-being programs were most acceptable. Educators-specified trained professionals should implement programs during school hours to male and female junior high students. Although eating disorder prevention was perceived as important, it was not rated as vital as other programs, such as substance abuse prevention.

    Tocopherols (vitamin E) and tea polyphenols have been reported to have cancer preventive activities. Large-scale human trials with high doses of alpha-tocopherol, however, have produced disappointing results. This review presents data showing that - and -tocopherols inhibit colon, lung, mammary and prostate carcinogenesis in animal models, whereas -tocopherol is ineffective in animal and human studies. Possible mechanisms of action are discussed. A broad cancer preventive activity of green tea polyphenols has been demonstrated in animal models, and many mechanisms have been proposed. The cancer preventive activity of green tea in humans, however, has not been conclusively demonstrated and remains to be further investigated.

    A survey has been conducted of cancer education programs for medical students in United States medical schools by the American Association for Cancer Education with grant support from the Department of Detection and Treatment of the American Cancer Society (formerly the Professional Education Department). Two questionnaires were used, an Educational Resources Questionnaire (ERQ), which 126 of the 128 medical schools completed and returned, and a Faculty and Curriculum Questionnaire (FCQ), which was completed and returned by 1,035 faculty members who had been named as active in undergraduate medical student cancer education by respondents in each school who had been designated by the Dean's Office to complete the ERQ. Overall conclusions included: (1) increased coordination of cancer education activities is a major need in many schools; (2) there is widespread interest in the further development of cancer education objectives; (3) development of a national cancer education curriculum is needed; (4) there is interest in the development of improved instructional materials and methods; (5) development of evaluation methods is needed for cancer education programs; and (6) an ongoing funding process is needed to provide support for interdepartmental coordination of cancer education activities. Cancer prevention and detection topics were ranked above cancer treatment in plans for future curriculum emphasis. More detailed conclusions and recommendations are provided in this publication and three subsequent articles in this issue of the Journal of Cancer Education.

    Selenium (Se) is an essential dietary component for all animals, including human beings, that is regarded as a protective agent against cancer. Although the mode of its anticancer action is not yet fully understood, several mechanisms, such as antioxidant protection through selenoenzymes, stimulation of DNA repair, and apoptosis in tumor prestages have all been proposed. Despite the unsupported results of the last "SELECT" trial, the cancer-preventing activity of Se has been demonstrated in a majority of epidemiological studies. Moreover, recent studies suggest that Se has a potential to be used not only in cancer prevention but also in cancer treatment, where in combination with other anticancer drugs or radiation it may increase the efficacy of cancer therapy. In combating cancer cells, Se acts as a prooxidant rather than an antioxidant, inducing apoptosis through the generation of oxidative stress. Thus, inorganic Se compounds, having high redox potency, represent a promising option in cancer therapy.

    Full Text Available Catechins are widely occurring in our diet and beverages. The cancer-preventive activities of catechins have been extensively studied. Of these, (−-epigallocatechin-3-gallate (EGCG, the principal catechin in green tea, has received the most attention. The inhibitory activities of tea catechins against carcinogenesis and cancer cell growth have been demonstrated in a large number of laboratory studies. Many mechanisms for modulating cancer signaling and metabolic pathways have been proposed based on numerous studies in cell lines with EGCG, the most active tea catechin. Nevertheless, it is not known whether many of these mechanisms indeed contribute to the anti-cancer activities in animals and in humans. Human studies have provided some results for the cancer preventive activities of tea catechins; however, the activities are not strong. This article reviews the cancer preventive activities and mechanisms of action of tea catechins involving their redox activities, biochemical properties and binding to key enzymes or signal transduction proteins. These mechanisms lead to suppression of cell proliferation, increased apoptosis and inhibition of angiogenesis. The relevance of the proposed mechanisms for cancer prevention are assessed in the light of the situation in vivo. The potential and possible problems in the application of tea and tea-derived products for cancer prevention are discussed.

    The Allium genus includes garlic, onions, shallots, leeks, and chives. These vegetables are popular in cuisines worldwide and are valued for their potential medicinal properties. Epidemiologic studies, while limited in their abilities to assess Allium consumption, indicate some associations of Allium vegetable consumption with decreased risk of cancer, particularly cancers of the gastrointestinal tract. Limited intervention studies have been conducted to support these associations. The majority of supportive evidence on Allium vegetables cancer-preventive effects comes from mechanistic studies. These studies highlight potential mechanisms of individual sulfur-containing compounds and of various preparations and extracts of these vegetables, including decreased bioactivation of carcinogens, antimicrobial activities, and redox modification. Allium vegetables and their components have effects at each stage of carcinogenesis and affect many biologic processes that modify cancer risk. This review discusses the cancer-preventive effects of Allium vegetables, particularly garlic and onions, and their bioactive sulfur compounds and highlights research gaps. ©2015 American Association for Cancer Research.

    Although cancer is a leading cause of morbidity and premature death among Latinos, there is limited knowledge of cancer-related issues and priorities of greatest significance to the Latino population, the largest minority group in the nation. This information is vital in helping to guide Latino cancer research, training, and awareness efforts at national, regional, and local levels. To help identify cancer issues of greatest relevance to Latinos, Redes En Accion, The National Hispanic/Latino Cancer Network, a major network among the National Cancer Institute's Special Populations Networks, conducted a survey of 624 key opinion leaders from around the country. Respondents were asked to rank the three cancer sites most important to Latinos in their region and the five issues of greatest significance for this population's cancer prevention and control. Recommendations were prioritized for three specific areas: 1) research, 2) training and/or professional education, and 3) awareness and/or public education. Among cancers, breast carcinoma was ranked number one, followed in order by cervical and lung carcinomas. The issues of greatest significance to Latinos were 1) access to cancer screening and care, 2) tobacco use, 3) patient-doctor communication, 4) nutrition, and 5) risk communication. This survey solicited information from scientists, health care professionals, leaders of government agencies, professional and community-based organizations, and other stakeholders in Latino health. The results laid the foundation for a national Redes En Accion Latino cancer agenda, thus providing a useful tool for individuals and organizations engaged in cancer prevention and control efforts among the Hispanic-Latino population.

    We describe the epidemiology, cancer prevention strategies, and educational messages to be learned from four characteristic cancers in Egypt: urinary bladder, liver, lung, and early-onset colorectal cancers. For bladder cancer, effective and convenient treatment of schistosomiasis, using social marketing and mass media in public and medical education has contributed dramatically to primary prevention of bladder cancer in Egypt. For liver cancer, educating hospital administrators to remove structural barriers to good practice may help the control of hepatitis transmission and related liver cancer. For lung cancer, the 50-year American experience for controlling tobacco smoking, beginning with physicians, could be very effective in Egypt and other countries with increasing smoking rates in the young so as to avert the expected epidemics of lung cancer. For colorectal cancer, more attention to physician and public education about the importance of interviewing colorectal cancer patients about a family history of cancer and the screening of at-risk families could be very effective in early detection of colorectal cancer. Countries with similar cancer epidemiology experience should make use of successful cancer prevention and education strategies that could be translated from the Egyptian experience.

    Spices have been widely used as food flavorings and folk medicines for thousands of years. Numerous studies have documented the antioxidant, anti-inflammatory and immunomodulatory effects of spices, which might be related to prevention and treatment of several cancers, including lung, liver, breast, stomach, colorectum, cervix, and prostate cancers. Several spices are potential sources for prevention and treatment of cancers, such as Curcuma longa (tumeric), Nigella sativa (black cumin), Zingiber officinale (ginger), Allium sativum (garlic), Crocus sativus (saffron), Piper nigrum (black pepper) and Capsicum annum (chili pepper), which contained several important bioactive compounds, such as curcumin, thymoquinone, piperine and capsaicin. The main mechanisms of action include inducing apoptosis, inhibiting proliferation, migration and invasion of tumors, and sensitizing tumors to radiotherapy and chemotherapy. This review summarized recent studies on some spices for prevention and treatment of cancers, and special attention was paid to bioactive components and mechanisms of action.

    Cancer is the leading cause of death in Puerto Rico, suggesting a need for improved strategies, programs, and resources devoted to cancer prevention. Enhanced prevention needs in Puerto Rico were initially identified in pilot studies conducted by the Ponce School of Medicine (PSM) in collaboration with the H. Lee Moffitt Cancer Center (MCC). In the current study, we used community engagement to identify specific needs in cancer prevention and education and strategies to create culturally attuned, effective cancer prevention education programs. A total of 37 participants attended a community forum and were assigned to one of three discussion groups: patients/survivors (n = 14); family/caregivers (n = 11); or healthcare providers (n = 12). Most participants were women (73 %), over 35 years of age, and a majority were married (58 %) and had a university education (81 %). The sessions were recorded and transcribed and analyzed for key themes. Participants wanted improved awareness of cancer prevention in Puerto Rico and believed cancer prevention education should start early, ideally in elementary school. Participants also stressed the importance of creating partnerships with private and government agencies to coordinate educational efforts. Suggested strategies included outreach to communities with limited resources, incorporating the testimony of cancer survivors, and utilizing social media to disseminate cancer prevention information.

    Science.gov (United States)

    The Division of Cancer Prevention conducts and supports research to determine a person's risk of developing cancer and to find ways to reduce that risk. Through laboratory, clinical, and epidemiologic research, scientists have shown that the diseases of cancer occur not as single, catastrophic events, but rather as the result of a complex and long-evolving molecular process that can take decades. This long-term process of carcinogenesis provides time and opportunities to slow down, stop, or reverse the cellular changes that can become cancer. | DCP research spans the initiation of cancer and the occurrence of invasive disease in major organ sites. The overall goal is to detect changes and intervene early to prevent symptomatic disease and death.

    Cancers are caused by mutations that may be inherited, induced by environmental factors, or result from DNA replication errors (R). We studied the relationship between the number of normal stem cell divisions and the risk of 17 cancer types in 69 countries throughout the world. The data revealed a strong correlation (median = 0.80) between cancer incidence and normal stem cell divisions in all countries, regardless of their environment. The major role of R mutations in cancer etiology was supported by an independent approach, based solely on cancer genome sequencing and epidemiological data, which suggested that R mutations are responsible for two-thirds of the mutations in human cancers. All of these results are consistent with epidemiological estimates of the fraction of cancers that can be prevented by changes in the environment. Moreover, they accentuate the importance of early detection and intervention to reduce deaths from the many cancers arising from unavoidable R mutations.

  2. Epidemiology and prevention of pancreatic cancer.

    Lowenfels, Albert B; Maisonneuve, Patrick

    2004-05-01

    Pancreatic cancer is an uncommon tumor, but because the mortality rate approaches 100%, this form of cancer has now become a common cause of cancer mortality. In the United States it is the fourth most frequent cause of cancer mortality; in Japan it ranks as the fifth commonest cause of death from cancer. Smoking is the major known risk factor for pancreatic cancer, accounting for approximately 25-30% of all cases. Some of the time-dependent changes in the frequency of pancreatic cancer can be explained by smoking trends. Aggressive public health measures to control smoking would substantially reduce the burden of pancreatic cancer. Dietary factors are less important for pancreatic cancer than for other digestive tract tumors, but consumption of a diet with adequate quantities of fruits and vegetables, plus control of calories either by dietary measures or by exercise will help to prevent this lethal tumor. There are more than a dozen inherited germline mutations that increase the risk of pancreatic cancer. Of these, hereditary pancreatitis confers the greatest risk, while BRCA2 mutations are the commonest inherited disorder. In addition to germline defects, there are several common polymorphisms in genes that control detoxification of environmental carcinogens that may alter the risk of pancreatic cancer. More research will be needed in this area, to explain and to clarify the interaction between genes and environmental factors.

    Healthy eating patterns and keeping physically active are potentially more important for chronic disease prevention than intake or exclusion of specific food items or nutrients. To this end, many health organizations routinely publish dietary and lifestyle recommendations aimed at preventing chronic disease. Using data from the Canadian National Breast Screening Study, we investigated the association between breast cancer risk and adherence to two sets of guidelines specific for cancer prevention, namely the American Cancer Society (ACS) Guidelines and the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) Recommendations. At baseline, 49,613 women completed dietary and lifestyle questionnaires and height and weight measurements were taken. During a mean follow-up of 16.6 years, 2,503 incident cases of breast cancer were ascertained. Cox proportional hazard models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association of meeting each guideline, and number of guidelines met, with breast cancer risk. The two sets of guidelines yielded similar results. Specifically, adherence to all six ACS guidelines was associated with a 31% reduction in breast cancer risk when compared to subjects adhering to at most one guideline (HR=0.69; 95% CI=0.49-0.97); similarly, adherence to six or seven of the WCRF/AICR guidelines was also associated with a 31% reduction in breast cancer risk (HR=0.69; 95% CI=0.47-1.00). Under either classification, meeting each additional guideline was associated with a 4-6% reduction in breast cancer risk. These results suggest that adherence to cancer prevention guidelines is associated with a reduced risk of breast cancer. © 2014 UICC.

    Two-thirds of cancer cases are associated with two lifestyle practices: 35% with the typical American diet, and 30% with tobacco use. In contrast to the field of tobacco control, research and resources dedicated to the field of nutrition have been limited, in part because dietary change has been considered controversial and requires a more complex set of interventions. This series of papers reviews the science base underlying diet as a cancer control strategy, including research about diet-cancer relationships, current nutrition policy recommendations, American dietary trends, models of dietary behavior change, and diet in health care delivery. The history of technology transfer of new knowledge into widespread application will be compared and contrasted with other cancer control measures. There is scientific and policy agreement about three priority dietary goals for the year 2000: increase fruit and vegetable consumption to 5 or more servings every day, increase breads, cereals, and legumes to 6 or more servings daily, and decrease fat to no more than 30% of total calories. Current data do not indicate that these goals will be reached. As yet there is no organized effort, with clearly identified steps, to translate research into practice. The parallel with delays in implementing other cancer control measures, including Papanicolaou testing, mammography, and tobacco intervention, is striking. Without resources dedicated to dietary modification in the general population, it is not likely that the potential savings of more than 300,000 new cases, 160,000 deaths, and the $25 billion in associated costs will be realized in the foreseeable future.

  7. Red Wine Polyphenols for Cancer Prevention

    2008-05-01

    Full Text Available Conventional cancer therapies, the second leading cause of death worldwide, result in serious side effects and, at best, merely extend the patient's lifespan by a few years. Searching for effective prevention is of high priority in both basic and clinical sciences. In recent decades natural products have been considered to be an important source of cancer chemopreventive agents. Red wine polyphenols, which consisted of various powerful antioxidants such as flavonoids and stilbenes, have been implicated in cancer prevention and that promote human health without recognizable side effects. Since resveratrol, a major component of red wine polyphenols, has been studied and reviewed extensively for its chemopreventive activity to interfere with the multi-stage carcinogenesis, this review focuses on recent progress in studies on cancer chemopreventive activities of red wine polyphenol extracts and fractions as well as other red wine polyphenols, like procyanidin B5 analogues and myricetin.

    An increasing body of scientific literature suggests that dietary components may exert cancer preventive effects. Tea, soy, cruciferous vegetables and other foods have been investigated for their cancer preventive potential. Some non-edible mushrooms like Reishi (Ganoderma lucidum) have a history use, both alone and in conjunction with standard therapies, for the treatment of various diseases including cancer in some cultures. They have shown efficacy in a number of scientific studies. By comparison, the potential cancer preventive effects of edible mushrooms have been less well-studied. With similar content of putative effective anticancer compounds such as polysaccharides, proteoglycans, steroids, etc., one might predict that edible mushrooms would also demonstrate anticancer and cancer preventive activity. In this review, available data for five commonly-consumed edible mushrooms: button mushrooms (Agaricus bisporus), A. blazei, oyster mushrooms (Pleurotus ostreatus), shiitake mushrooms (Lentinus edodes), and maitake (Grifola frondosa) mushrooms is discussed. The results of animal model and human intervention studies, as well as supporting in vitro mechanistic studies are critically evaluated. Weaknesses in the current data and topics for future work are highlighted.

  10. Flavin-Dependent Enzymes in Cancer Prevention

    2012-12-01

    Full Text Available Statistical studies have demonstrated that various agents may reduce the risk of cancer’s development. One of them is activity of flavin-dependent enzymes such as flavin-containing monooxygenase (FMOGS-OX1, FAD-dependent 5,10-methylenetetrahydrofolate reductase and flavin-dependent monoamine oxidase. In the last decade, many papers concerning their structure, reaction mechanism and role in the cancer prevention were published. In our work, we provide a more in-depth analysis of flavin-dependent enzymes and their contribution to the cancer prevention. We present the actual knowledge about the glucosinolate synthesized by flavin-containing monooxygenase (FMOGS-OX1 and its role in cancer prevention, discuss the influence of mutations in FAD-dependent 5,10-methylenetetrahydrofolate reductase on the cancer risk, and describe FAD as an important cofactor for the demethylation of histons. We also present our views on the role of riboflavin supplements in the prevention against cancer.

    2015-01-01

    Full Text Available Cardiovascular disease (CVD has been the number one cause of death in the U.S. for 114 of the last 115 years. Risk factors for prostate cancer have primarily mirrored risk proven risk factors for CVD, especially aggressive disease. Obesity, dyslipidemia, glucose intolerance, metabolic syndrome, unhealthy dietary habits or caloric excess, lack of physical activity, and inflammation are just some of these shared risk factors. The evidence also suggests proven CVD preventive measures are identical to prostate cancer preventive measures, especially in regard to aggressive disease. Thus, apart from lifestyle measures that can encourage optimal heart and prostate health there are potentially several dietary supplements that need to be avoided in healthy men because they may also increase the risk of prostate cancer. However, there are also several low-cost, generic, safe in the appropriate individuals, and naturally derived agents that could reduce prostate cancer risk, and these can be discussed and remembered utilizing the acronym S.A.M. (statins, aspirin, and/or metformin.

    2008-02-01

    Discussions of pediatric nutrition and cancer usually focus on important issues of ensuring an adequate nutrient intake (enteral and parenteral) during and after the early treatment phase of care. However, information is available that suggests that vitamin status may have additional roles in the care of children with cancer. Over the last decade, investigators have reported findings that suggest that maternal preconception and perinatal vitamin intake and status influence the cancer risk of the infant and child. Others have shown a relationship between vitamin and antioxidant status and the prevalence and severity of adverse side effects for children undergoing chemotherapy. Vitamin D has potential anti-cancer activity and vitamin D status is suboptimal in many children in North America. Each of these issues is briefly presented from a perspective of prevention and treatment of childhood cancer.

    2011-12-01

    This study aimed to identify what undergraduate students know of factors for breast cancer prevention. This was a quantitative, exploratory and descriptive study, developed in a University in the state of Santa Catarina, Brazil with 50 students enrolled in nursing, physiotherapy and psychology programs in the first semester of 2008. The data were collected from February to April 2008. A semi-structured questionnaire and descriptive statistics were used. Results showed that students of nursing and physiotherapy demonstrated greater knowledge about the issue than the psychology students. Mentioned prevention factors: consumption of vegetables, greens and fruits, physical exercises and breastfeeding. Conclusions indicate that the level of students' knowledge about factors that can prevent breast cancer, in an interdisciplinary perspective, is important to rethink the inclusion of health education as an essential curriculum content to promote a healthy university.

    High intakes of the macronutrients--proteins, lipids, and carbohydrates in the form of excess energy-have some cancer stimulating properties. On the contrary, epidemiologic and animal laboratory data indicate that high-level supplementation of some micronutrients--certain vitamins, minerals, and lipotropes, as well as some non-nutrients, most notably various types of dietary fiber, may be useful in the prevention of cancer. A wealth of data exists for macronutrients whereas most micronutrients are almost unstudied concerning their role in cancer prevention. Vitamins A, E, and C and selenium are the most well-studied micronutrients, and are recognized as effective with significant anticancer effects, at least in animal models. There are minimal data to suggest that some other micronutrients may also exert varying degrees of incidence reduction on one or more types of cancer. This is most true for folic acid, manganese, molybdenum, copper, the amino acids phenylalanine and methionine, and the lipotrope choline. Zinc and vitamins B1, B2, B6, B12 and pantothenic acid have even less data, and some data are contradictory. Therefore, it is premature to make recommendations concerning their usefulness in cancer prevention at present.

    2015-08-01

    Full Text Available Breast cancer survivors are at risk of developing a second primary cancer. Colorectal cancer (CRC is one of the leading second primary cancers, and it is often preventable. We developed a multi-component educational tool to inform and encourage women breast cancer survivors to engage in CRC screening. To assess the strengths and weakness of the tool and to improve the relevancy to the target audience, we convened four focus groups of women breast cancer survivors in Missouri. We also assessed the potential impact of the tool on the knowledge, attitudes, and beliefs regarding CRC and collected information on the barriers to CRC screening through pre- and post-focus groups’ questionnaires. A total of 43 women breast cancer survivors participated and provided very valuable suggestions on design and content to update the tool. Through the process and comparing pre- and post-focus group assessments, a significantly higher proportion of breast cancer survivors strongly agreed or agreed that CRC is preventable (78.6% vs. 96.9%, p = 0.02 and became aware that they were at a slightly increased risk for CRC (18.6% vs. 51.7%, p = 0.003. The most cited barrier was the complexity of preparation for colonoscopy.

    2016-02-01

    Colorectal cancer (CRC), the third major cause of mortality among various cancer types in United States, has been increasing in developing countries due to varying diet and dietary habits and occupational hazards. Recent evidences showed that composition of gut microbiota could be associated with the development of CRC and other gut dysbiosis. Modulation of gut microbiota by probiotics and prebiotics, either alone or in combination could positively influence the cross-talk between immune system and microbiota, would be beneficial in preventing inflammation and CRC. In this review, role of probiotics and prebiotics in the prevention of CRC has been discussed. Various epidemiological and experimental studies, specifically gut microbiome research has effectively improved the understanding about the role of probiotics and microbial treatment as anticarcinogenic agents. A few human studies support the beneficial effect of probiotics and prebiotics; hence, comprehensive understanding is urgent to realize the clinical applications of probiotics and prebiotics in CRC prevention.

    Cancer imposes a heavy societal burden worldwide, in terms of both epidemiology and costs. The introduction of more sophisticated imaging and diagnostic techniques and advanced drugs that specifically target tumor cells is leading to increasingly expensive treatments, which may be affordable only for few patients. Prevention, and particularly primary prevention, is an effective way of addressing the challenging issue of cancer, since between a third and a half of cancers could be prevented on the basis of our current knowledge of risk factors. Moreover, prevention is cost-effective, its effects are not limited to high-risk subjects but extend to the entire population, and it is not dependent on socioeconomic status. Regulatory measures can have a broad impact, even on future generations; by empowering and educating subjects, promoting healthy behaviours and teaching self-care, they can trigger a virtuous cycle. In recent decades, oncology has shifted from being merely reactive to being proactive; this shift has led to the development of so-called "P4 medicine", where the 4 Ps stand for "preventive", "predictive", "personalized" and "participatory". Prevention programs are an important part of the effort to control cancer, as they are able to reduce both the incidence of cancer and mortality. For instance, screening for colorectal, breast and cervical cancer is reducing the burden of these common tumors. Anti-cancer vaccines, both prophylactic and therapeutic, constitute another important preventive tool. Although progress has been made in these areas, much remains to be done. With regard to screening programs, coverage could be increased by introducing new, more acceptable, less invasive tests, stratifying screening through correlation with anamnestic, clinical, radiological and genomic data (so-called "populationbased personalized cancer screening"), and exploiting new information and communication technologies, such as smartphone applications or personalized text

    2014-07-01

    Full Text Available Introduction Cancer is a worldwide problem as it will affect one in three men and one in four women during their lifetime. Colorectal cancer (CRC is the third most frequent cancer in men, after lung and prostate cancer, and is the second most frequent cancer in women after breast cancer. It is also the third cause of death in men and women separately, and is the second most frequent cause of death by cancer if both genders are considered together. CRC represents approximately 10% of deaths by cancer. Modifiable risk factors of CRC include smoking, physical inactivity, being overweight and obesity, eating processed meat, and drinking alcohol excessively. CRC screening programs are possible only in economically developed countries. However, attention should be paid in the future to geographical areas with ageing populations and a western lifestyle. 19 , 20 Sigmoidoscopy screening done with people aged 55-64 years has been demonstrated to reduce the incidence of CRC by 33% and mortality by CRC by 43%. Objective To assess the effect on the incidence and mortality of CRC diet and lifestyle and to determine the effect of secondary prevention through early diagnosis of CRC. Methodology A comprehensive search of Medline and Pubmed articles related to primary and secondary prevention of CRC and subsequently, a meta-analysis of the same blocks are performed. Results 225 articles related to primary or secondary prevention of CRC were retrieved. Of these 145 were considered valid on meta-analysis: 12 on epidemiology, 56 on diet and lifestyle, and over 77 different screenings for early detection of CRC. Cancer is a worldwide problem as it will affect one in three men and one in four women during their lifetime. There is no doubt whatsoever which environmental factors, probably diet, may account for these cancer rates. Excessive alcohol consumption and cholesterol-rich diet are associated with a high risk of colon cancer. A diet poor in folic acid and vitamin

  5. Cancer preventive role of selected dietary factors

    Directory of Open Access Journals (Sweden)

    Ray Amitabha

    2005-01-01

    Full Text Available Dietary behavior seems to be an important modifiable determinant for the risk of cancer. The evidences from several epidemiological studies suggest that higher intakes of fruits and vegetables have been associated with lower risk of cancer. Dietary phenolic and polyphenolic substances, terpenoids, dietary fibers, fish oils, some micronutrients present in foods of both plant and animal origin, and a reduction of caloric intake appear to inhibit the process of cancer development. Many dietary factors possess antioxidant and anti-inflammatory properties and cause induction of phase II enzymes like glutathione-S-transferases. It has been suggested that cruciferous vegetables play an important role in cancer prevention, and their chemopreventive effects are due to high glucosinolate content which under enzymatic hydrolysis produces bioactive compound isothiocyanates. Further, isothiocyanates of a wide variety of cruciferous vegetables are powerful inhibitors of carcinogenesis in experimental animal models. Several flavonoids present in fruits, tea, soya beans, etc. may be useful as cancer preventive agents. Similarly, ellagic acid, perillyl alcohol and resveratrol found in various fruits may have chemoprotective effect. Moreover, different vanilloids such as curcumin and gingerol have been shown to possess antioxidative properties. Nevertheless, in spite of several studies, still the effects of various ingredients are not clearly distinguished. In human, little convincing evidence has been established for the proposed protective effects of dietary constituents. It is an important future research goal to provide necessary evidences to support the chemopreventive role of different dietary factors, and also to clarify misunderstandings in this perplexing area.

    Full Text Available Introduction: Cytological examination is a simple and inexpensive method used in the prevention of cervical cancer. In Poland, too low proportions of women still have the test. Aim of the research : To analyse the attitudes towards cervical cancer prevention. Material and methods : Two hundred and ten hospitalized women were invited to take part in the investigation. The research used the diagnostic poll method, using the author’s original questionnaire form. The research was carried out in four gynaecological wards. Results : Of the women who participated in the research, 16.2% by the time of diagnosis had never received a Pap test. In the analysed group, 88.2% of women were not referred to a specialist for a Pap test. Among all respondents, only 35.7% underwent cervix cytology regularly, i.e. once a year or once every 2 years. Conclusions : The effort made by the women towards the attitudes of cervical cancer prevention was insufficient; still too many women had not reported to the specialist for taking material from the cervix, or did not do so regularly. A significant relation in the behaviour of women was found depending on their level of education and place of residence. Greater activity of nurses, midwives and family physicians in stimulating Polish women to participate in prevention programmes for cervical cancer is advisable. To increase the health awareness of girls and women, it is important to include in the curriculum, especially in secondary schools, the issues of prevention of female reproductive system cancer.

    Community misconception of what causes cancer is an important consideration when devising communication strategies around cancer prevention, while those initiating social marketing campaigns must decide whether to target the general population or to tailor messages for different audiences. This paper investigates the relationships between demographic characteristics, identification of selected cancer risk factors, and associated protective behaviours, to inform audience segmentation for cancer prevention social marketing. Data for this cross-sectional study (n = 3301) are derived from Cancer Council New South Wales' 2013 Cancer Prevention Survey. Descriptive statistics and logistic regression models were used to investigate the relationship between respondent demographic characteristics and identification of each of seven cancer risk factors; demographic characteristics and practice of the seven 'protective' behaviours associated with the seven cancer risk factors; and identification of cancer risk factors and practising the associated protective behaviours, controlling for demographic characteristics. More than 90% of respondents across demographic groups identified sun exposure and smoking cigarettes as moderate or large cancer risk factors. Around 80% identified passive smoking as a moderate/large risk factor, and 40-60% identified being overweight or obese, drinking alcohol, not eating enough vegetables and not eating enough fruit. Women and older respondents were more likely to identify most cancer risk factors as moderate/large, and to practise associated protective behaviours. Education was correlated with identification of smoking as a moderate/large cancer risk factor, and with four of the seven protective behaviours. Location (metropolitan/regional) and country of birth (Australia/other) were weak predictors of identification and of protective behaviours. Identification of a cancer risk factor as moderate/large was a significant predictor for five out

  9. Helicobacter pylori eradication for preventing gastric cancer.

    Lu, Bin; Li, Meng

    2014-05-21

    Helicobacter pylori (H. pylori) infection is a major risk factor for gastric cancer (GC) development, which is one of the most challenging malignant diseases worldwide with limited treatments. In the multistep pathogenesis of GC, H. pylori infection slowly induces chronic active gastritis, which progresses through the premalignant stages of atrophic gastritis, intestinal metaplasia, and dysplasia, and then finally to GC. Although eradication of H. pylori is a reasonable approach for the prevention of GC, there have been some contradictory reports, with only some long-term follow-up data showing efficacy of this approach. The inconsistencies are likely due to the insufficient number of participants, relatively short follow-up periods, poor quality of study designs, and the degree and extent of preneoplastic changes at the time of H. pylori eradication. This review analyzes recent high-quality studies to resolve the discrepancies regarding the eradication of H. pylori for GC prevention. The relationship between H. pylori eradication and GC/precancerous lesions/metachronous GC is examined, and the cost-effectiveness of this strategy in the prevention of GC is assessed. Although it is assumed that eradication of H. pylori has the potential to prevent GC, the feasibility and appropriate timing of this strategy for cancer prevention remain to be determined. As a result, additional well-designed trials with longer follow-up periods are needed to clarify this issue.

    Outcome-expectation beliefs and knowledge may ultimately influence behavior for cancer prevention. The aims of this study were to measure changes in knowledge and beliefs about cancer prevention before and after viewing a television advertisement and identify the factors affecting receptivity to its messages. A one-group pretest-posttest design was used in this study of 1,000 individuals aged 20 to 65 years who were recruited online in November 2014. The outcome variables included cancer prevention beliefs based on the Health Belief Model (five items) and knowledge about risk factors for cancer (seven items). Perceived susceptibility, perceived benefits, and self-efficacy increased significantly and their perceived severity and perceived barriers decreased significantly, after participants viewed the television advertisement. Correct responses to questions about risk factors also increased significantly, except for smoking. The main factors affecting changes in the outcome variables were age, interest in cancer prevention, social network, satisfaction with the ad, and pretest scores. Television advertisements with positive frameworks can be an efficient channel of improving beliefs and knowledge about cancer prevention in a short period. The continuous development of intervention materials that consider the demographics, needs, and satisfaction of the target group will be necessary for future studies.

    AIM: To investigate gastric cancer screening and preventive behaviors among the relatives of patients with gastric cancer [i.e., gastric cancer relatives (GCRs)]. METHODS: We examined the Korean National Health and Nutrition Examination Survey 2005 (KNHANES Ⅲ) database and compared the gastric cancer screening and preventive behaviors of GCRs (n = 261) with those of non-GCRs (n = 454) and controls without a family history of cancer (n = 2842). RESULTS: The GCRs were more likely to undergo gastric cancer screening compared with the control group (39.2% vs 32.3%, adjusted odds ratio: 1.43, CI: 1.05-1.95), although the absolute screening rate was low. Dietary patterns and smoking rates did not differ significantly between the groups, and a high proportion of GCRs reported inappropriate dietary habits (i.e., approximately 95% consumed excessive sodium, 30% were deficient in vitamin C, and 85% were deficient in dietary fiber). CONCLUSION: The gastric cancer screening and preventive behaviors of GCRs have yet to be improved. To increase awareness among GCRs, systematic family education programs should be implemented.

  12. Molecular Link between Vitamin D and Cancer Prevention

    William B. Grant

    2013-09-01

    Full Text Available The metabolite of vitamin D, 1α,25-dihydroxyvitamin D3 (also known as calcitriol, is a biologically active molecule required to maintain the physiological functions of several target tissues in the human body from conception to adulthood. Its molecular mode of action ranges from immediate nongenomic responses to longer term mechanisms that exert persistent genomic effects. The genomic mechanisms of vitamin D action rely on cross talk between 1α,25-dihydroxyvitamin D3 signaling pathways and that of other growth factors or hormones that collectively regulate cell proliferation, differentiation and cell survival. In vitro and in vivo studies demonstrate a role for vitamin D (calcitriol in modulating cellular growth and development. Vitamin D (calcitriol acts as an antiproliferative agent in many tissues and significantly slows malignant cellular growth. Moreover, epidemiological studies have suggested that ultraviolet-B exposure can help reduce cancer risk and prevalence, indicating a potential role for vitamin D as a feasible agent to prevent cancer incidence and recurrence. With the preventive potential of this biologically active agent, we suggest that countries where cancer is on the rise—yet where sunlight and, hence, vitamin D may be easily acquired—adopt awareness, education and implementation strategies to increase supplementation with vitamin D in all age groups as a preventive measure to reduce cancer risk and prevalence.

    Cervical cancer remains a serious public health problem in the world; that is why the Mexican Federation of Schools of Obstetrics and Gynecology convened the elaboration of a consensus that is devoted this number of Ginecologia y Obstetricia de Mexico. In recent years has strengthened perceptions (public and private) in the need for preventive strategies in the medium and long terms. The development of effective vaccines against the human papilloma virus and the application of new methods of detection from viral DNA (completely automated for personal application) allow some degree of optimism. It is proposed a consensus with general recommendations in two consecutive stages: (a) primary prevention consisting of education for the prevention of cervical cancer and universal immunization and (b) secondary prevention by early detection of infections or injuries that could favor carcinogenesis. The consensus reviewed characteristics of available vaccines in detail and proposes strategies for implementation in Mexican population. Also, check out main methods of early detection of infection (or predisposing lesions) and suggests public and private strategies for implementation. Consensus places particular emphasis on early immunization for female population and correct use of methods for detection of infections or injuries that might cause cervical cancer.

Eighty percent of prostate cancer patients aged over 65 years. Prostate cancer occurs due to accumulation of DNA damage. There are various mechanisms that cause DNA damage, one of them is due to oxidative stress. Imbalance levels of free radicals and antioxidant in tissues causes oxidative stress. Antioxidants are substance that has ability to neutralize free radicals. One of the powerful antioxidant is lycopene. It is belived have ability to prevent prostate cancer. Various studies and reviews have been conducted to determine the role of lycopene in the prevention of prostate cancer.

    The Selenium and Vitamin E Cancer Prevention Trial (SELECT) was conducted to assess the efficacy of selenium and vitamin E alone, and in combination, on the incidence of prostate cancer. This randomized, double-blind, placebo-controlled, 2 × 2 factorial design clinical trial found that neither selenium nor vitamin E reduced the incidence of prostate cancer after seven years and that vitamin E was associated with a 17% increased risk of prostate cancer compared to placebo. The null result was surprising given the strong preclinical and clinical evidence suggesting chemopreventive activity of selenium. Potential explanations for the null findings include the agent formulation and dose, the characteristics of the cohort, and the study design. It is likely that only specific subpopulations may benefit from selenium supplementation; therefore, future studies should consider the baseline selenium status of the participants, age of the cohort, and genotype of specific selenoproteins, among other characteristics, in order to determine the activity of selenium in cancer prevention.

    Breast cancer is a devastating illness but cure rates are increasing and as they do the secondary effects of breast cancer treatment on bone are becoming more prominent. Of particular concern is the increased fracture rates and dramatic bone loss seen in studies of patients undergoing therapy with aromatase inhibitors. Recently a UK Expert Group has drawn up guidelines for the prevention of bone loss. The main recommendations can be summarised as follows: Bone loss in women who experience a premature menopause due to treatment before the age of 45 or who are receiving ovarian suppression therapy is accelerated by the concomitant use of aromatase inhibitors. As they are at high risk of significant bone loss they should have a baseline dual energy X-ray absorptiometry (DXA) assessment of BMD. As randomised clinical trials in postmenopausal women indicate that bisphosphonates prevent the bone loss and accelerated bone turnover associated with aromatase inhibitor therapy their use as the main preventative therapy is recommended, along with a healthy lifestyle and adequate intake of calcium and vitamin D. Decisions on the initiation of treatment initiation should be based on a combination of risk factors for osteoporotic fracture and BMD levels. Due to the rate of bone loss associated with breast cancer treatments, and uncertainties about the interaction between aromatase inhibitor use and BMD for fracture risk, the thresholds for intervention have been set at a higher levels than generally recommended for postmenopausal osteoporosis.

    Dramatic advances in our understanding of cancer causation have come from epidemiologic and laboratory research, particularly over the past two decades. These developments have included a broadening interest in the critical events that take place during the early stages of the dynamic multistep process leading to - vasive cancer. Increasingly, cancer epidemiologists are pursuing research into the origins and natural history of premalignant lesions, including intermediate or surrogate endpoints, a trend - celerated by the development of molecular technologies that are revolutionizing our understanding of the transformation of normal to malignant cells. There seems little doubt that this emerging knowledge will provide further insights not only into carcinogenic processes, but also into more sensitive methods of early detection and more effective means of prevention. In this book, Drs. Franco and Rohan have succeeded in prep- ing a comprehensive, timely, and critical review of the substantial progress that has ...

  18. Photocarcinogenesis and Skin Cancer Prevention Strategies.

    Seebode, Christina; Lehmann, Janin; Emmert, Steffen

    2016-03-01

    In this review the basic principles of UV-induced carcinogenesis are summarized and the state of the art diagnosis and therapeutic strategies are discussed. The prevalent keratinocyte-derived neoplasms of the skin are basal cell and squamous cell carcinomas. Cutaneous melanoma is less frequent but associated with high mortality. Common risk factors for all three tumor entities include sun exposure and DNA-repair deficiencies. Photocarcinogenesis follows a multistep model of cancer development in which ultraviolet-induced DNA damage leads to mutations resulting in activation of oncogenes or silencing of tumor-suppressor genes. This ends in a cellular mutator phenotype even more prone to mutation acquisition. DNA repair, especially the nucleotide excision repair (NER) pathway, counteracts mutation formation and skin cancer development. This is vividly demonstrated by the NER-defective disorder xeroderma pigmentosum. Primary skin cancer preventative strategies, therefore, include reduction of DNA photodamage by protection from the sun. Secondary preventative strategies include skin cancer screening. This implies standard examination techniques with the naked eye, an epiluminescence microscope, or digital epiluminescence microscopy. More advanced techniques include confocal laser scan microscopy.

  19. Rapalogs in cancer prevention: anti-aging or anticancer?

    Science.gov (United States)

    Blagosklonny, Mikhail V

    2012-12-01

    Common cancer is an age-related disease. Slow aging is associated with reduced and delayed carcinogenesis. Calorie restriction (CR), the most studied anti-aging intervention, prevents cancer by slowing down the aging process. Evidence is emerging that CR decelerates aging by deactivating MTOR (Target of Rapamycin). Rapamycin and other rapalogs suppress cellular senescence, slow down aging and postpone age-related diseases including cancer. At the same time, rapalogs are approved for certain cancer treatments. Can cancer prevention be explained by direct targeting of cancer cells? Or does rapamycin prevent cancer indirectly through slowing down the aging process? Increasing evidence points to the latter scenario.

    Full Text Available Abstract: Introduction: Cancer is a global problem as it will affect one in three men and one in four women during their lifetime. Colorectal cancer (CRC is the second most common cancer in men, after lung cancer, and is the second most common cancer in women after breast cancer. It is also the second leading cause of death in men and women separately, and is the second most common cause of cancer death if both genders are considered together. CRC accounts for approximately 10% of cancer deaths. Modifiable risk factors for CRC include smoking, physical inactivity, overweight and obesity, processed meat consumption, and excessive alcohol consumption. CRC screening programs are possible in economically developed countries. However, attention should be paid in the future to geographically populated areas and western lifestyles. Objective: To evaluate the effect on the incidence and mortality of diet and lifestyle of CRC and to determine the effect of secondary prevention through the early diagnosis of CRC. Methodology: An exhaustive search of Medline and Pubmed articles related to primary and secondary prevention of CRC is carried out and a meta-analysis of the same blocks is carried out. Results: 301 items related to primary or secondary prevention of CRC were recovered. Of these, 177 were considered valid in the meta-analysis: 12 in epidemiology, 56 in diet and lifestyle, and over 77 different projections for the early detection of CRC. Cancer is a global problem as it will affect one in three men and one in four women during their lifetime. There is no question of which environmental factors, probably diet, may explain these cancer rates. Excessive consumption of alcohol and high cholesterol diet are associated with a high risk of colon cancer. A diet low in folic acid and vitamin B6 is also associated with an increased risk of developing colon cancer with overexpression of p53. Eating pulses at least three times a week reduces the risk of

    Even though the field of medicine has developed tremendously, the wide variety of cancer is still among chronic and life threatening disease today. Therefore, the specialists constantly research and try every possible way to find cure or preventive ways to stop its further development. For this reason, studies concerning the chronic disease such as cancer have been spread to many different fields. In this regard, many other alternative ways besides medicine, are used in prevention of cancer. Nutritional therapy, herbal therapy, sportive activities, art therapy, music therapy, dance therapy, imagery, yoga and acupuncture can be given as examples. Among these, dance/movement therapy which deals with individuals physical, emotional, cognitive as well as social integration is widely used as a popular form of physical activity. The physical benefits of dance therapy as exercise are well documented. Studies have shown that physical activity is known to increase special neurotransmitter substances in the brain (endorphins), which create a state of well-being. And total body movement such as dance enhances the functions of other body systems, such as circulatory, respiratory, skeletal, and muscular systems. Regarding its unique connection to the field of medicine, many researches have been undertaken on the effects of dance/movement therapy in special settings with physical problems such as amputations, traumatic brain injury, and stroke, chronic illnesses such as anorexia, bulimia, cancer, Alzheimer's disease, cystic fibrosis, heart disease, diabetes, asthma, AIDS, and arthritis. Today dance/movement therapy is a well recognized form of complementary therapy used in hospitals as well as at the comprehensive clinical cancer centres.

    The National Cancer Institute (NCI) supported four innovative demonstration research projects, "The Digital Divide Pilot Projects," to test new strategies for disseminating health information via computer to vulnerable consumers. These projects involved active research collaborations between the NCI's Cancer Information Service (CIS) and regional cancer control researchers to field test new approaches for enhancing cancer communication in vulnerable communities. The projects were able to use computers to successfully disseminate relevant cancer information to vulnerable populations. These demonstration research projects suggested effective new strategies for using communication technologies to educate underserved populations about cancer prevention, control, and care.

    The purpose of this work is to evaluate the utilization of information gathered by multiphasic screening with respect to lung cancer detection and smoking cessation techniques. A cohort (follow-up) study is reported in which cancer incidence and factors affecting its occurrence are evaluated in a group of about 20,000 presumably healthy adults along a period of approximately 10 years following comprehensive multiphasic health examinations. Lung cancer occurrence is primarily related to smoking. The risk is higher in smokers and is dose-dependent; OR = 0.21, (CI = 0.08, .53) in never smokers, OR = 1.53 (CI = 0.8, 3.2) in past and current moderate smokers, OR = 4.92 (CI = 2.18, 11.11) in current heavy smokers. Moreover, smokers with compromised pulmonary function (FEVI/FVC periodical multiphasic health examinations could be utilized by health professionals to encourage smoking cessation and smoking prevention in the appropriate screenees. Various elements of the multiphasic test results could contribute to such prevention efforts. While every smoker should receive appropriate evaluation and consultation regarding nicotine dependence, smokers with reduced pulmonary function represent an extra high risk group to which special attention should be given.

    Morinda citrifolia (Noni) has been extensively used in folk medicine by Polynesians for over 2,000 years. It has been reported to have broad therapeutic effects, including anticancer activity, in both clinical practice and laboratory animal models. The mechanism for these effects remains unknown. The hypothesis that Morinda citrifolia possesses a cancer preventive effect at the initiation stage of carcinogenesis was studied. Our preliminary data indicated that 10% Tahitian Noni Liquid Dietary Supplement or Tahitian Noni Juice (TNJ), made from Morinda citrifolia fruit by Morinda Inc, in drinking water for one week was able to prevent DMBA-DNA adduct formation. The levels of DMBA-DNA adducts were reduced by 30% in the heart, 41% in the lung, 42% in the liver, and 80% in the kidney of female SD rats. Even more dramatic results were obtained in male C57 BL-6 mice: 10% TNJ was able to reduce DMBA-DNA adduct formation by 60% in the heart, 50% in the lung, 70% in the liver, and 90% in the kidney. In order to explore the mechanism of this preventive effect, the antioxidant activity of TNJ was examined in vitro by lipid hydroperoxide (LPO) and tetrazolium nitroblue (TNB) assays. In the LPO assay, LPO oxidizes leucomethylene blue to methylene blue in the presence of hemoglobin. The resultant blue color was quantified at 660 nm spectrophotometrically. In the TNB assay, superoxide anion radicals (SAR) reduce TNB into formazan blue that was also measured by absorption at 602 nm. TNJ showed a dose-dependent inhibition of both LPO and SAR in our system. The antioxidant activity of TNJ was compared to the effects of vitamin C, grape seed powder (GSP), and pycnogenol (PYC) at the daily dose per serving level recommended by U.S.RDAs or manufacturers. The results suggest that prevention of carcinogen-DNA adduct formation and the antioxidant activity of TNJ may contribute to the cancer preventive effect of Morinda citrifolia.

    The increasing number of new cases of cancer highlights the relevance of primary prevention for cancer control, which is influenced, among other factors, by the population's health-related knowledge. Therefore, we aimed to describe cancer-related knowledge in Portugal, including perception of risk, awareness of cancer causes and preventive behaviours. We evaluated 1624 Portuguese-speaking dwellers, aged between 16 and 79 years, through face-to-face interviews conducted using a structured questionnaire. We computed adjusted (sex, age, education) regression coefficients and prevalence ratios, using linear and Poisson regression, respectively, to quantify associations with cancer-specific knowledge. The proportions of nonresponse ranged from 13.4 to 63.5% for the most frequent cancer in Portugal and the leading cause of cancer, respectively. The mean of the estimated lifetime risk of cancer in the Portuguese population was 37.0%. A total of 47.5% of the respondents identified breast cancer as the most frequent in Portugal, 72.0% named lifestyles as the leading cause of cancer and 40.2% selected not smoking as the most important preventive behaviour. Lower levels of education were associated with higher proportions of nonresponse, but not consistently with inaccurate knowledge. Men provided lower estimates of the lifetime risk of cancer, indicated breast cancer less frequently and more often lung cancer as the most frequent, and were more likely to select not smoking as the most important preventive behaviour. The present study provides relevant data on knowledge of cancer prevention, which may be used for the planning and evaluation of awareness-raising and primary prevention interventions in Portugal.

  6. Oral cancer preventive campaigns: are we reaching the real target?

    2015-02-01

    Full Text Available Introduction: Oral cavity malignant neoplasms have a high mortality rate. For this reason, preventive campaigns have been developed, both to educate the population and to diagnose lesions at an early stage. However, there are studies that contest the validity of these endeavors, principally because the target audience of the campaigns may not conform to the group at highest risk for oral malignancy. Objective: To describe the profile of patients who avail themselves of the preventive campaign, identify the presence of oral lesions in that population, and compare that data with the epidemiological profile of patients with oral cancer. Methods: Cross-sectional historical cohort study performed by analysis of epidemiological data of the campaign "Abra a Boca para a Saúde" collected in the years from 2008 to 2013. Results: In the years analyzed, 11,965 people were treated and 859 lesions were diagnosed, all benign. There was a female predominance (52.7%, with mean age of 44 years (±15.4 years; 26% were smokers and 29% reported alcohol consumption. It is known that the group at highest risk to develop oral cancer is 60to 70-year-old men, who are alcoholic smokers. Conclusion: The population that seeks preventive campaigns is not the main risk group for the disease. This fact explains the low number of lesions and the lack of cancer detection.

    Although breast cancer prevention targets mostly women ages 40 and older, little is known about breast cancer prevention for young women and mother's advice. The purpose of this study was to examine breast cancer prevention knowledge, attitudes, and behaviors among college women and mother-daughter communication. Hispanic and non-Hispanic students at a southwestern university completed a breast cancer prevention survey with items for mother's advice, breast self-awareness and risk reduction knowledge, self-efficacy, susceptibility, family history, provider breast self-exam (BSE) recommendation, peer norms, BSE practice, and demographics. An openended item was also used to elicit types of mother's advice. Logistic regression was used to assess predictors for receiving mother's advice for breast cancer prevention and BSE practice. Self-reported data using a survey were obtained from 546 college women with a mean age of 23.3 (SD = 7.75). Nearly 36 % received mothers' advice and 55 % conducted BSE. Predictors for receiving mother's advice were age, self-efficacy, and family history of breast cancer. Predictors for BSE practice were mother's advice, age, self-efficacy, and provider BSE recommendation. Family history of breast cancer and knowledge were not significant predictors for BSE practice. Findings support the need for clinicians, community health educators, and mothers to provide breast cancer prevention education targeting college women.

    Out-of-pocket expenditures are thought to be an important barrier to the receipt of cancer preventive services, especially for those of a lower socioeconomic status (SES). The Affordable Care Act (ACA) eliminated out-of-pocket expenditures for recommended services, including mammography and colonoscopy. The objective of this study was to determine changes in the uptake of mammography and colonoscopy among fee-for-service Medicare beneficiaries before and after ACA implementation. Using Medicare claims data, this study identified women who were 70 years old or older and had not undergone mammography in the previous 2 years and men and women who were 70 years old or older, were at increased risk for colorectal cancer, and had not undergone colonoscopy in the past 5 years. The receipt of procedures in the 2-year period before the ACA's implementation (2009-2010) and after its implementation (2011 to September 2012) was also identified. Multivariate generalized estimating equation models were used to determine the independent association and county-level quartile of median income and education with the receipt of testing. For mammography, a lower SES quartile was associated with less uptake, but the post-ACA disparities were smaller than those in the pre-ACA period. In addition, mammography rates increased from the pre-ACA period to the post-ACA period in all SES quartiles. For colonoscopy, in both the pre- and post-ACA periods, there was an association between uptake and educational level and, to some extent, income. However, there were no appreciable changes in colonoscopy and SES after implementation of the ACA. The removal of out-of-pocket expenditures may overcome a barrier to the receipt of recommended preventive services, but for colonoscopy, other procedural factors may remain as deterrents.

    Reduced rates of lung cancer have been observed in several occupational groups exposed to high levels of organic dusts contaminated by endotoxin. The underlying anti-neoplastic mechanism of endotoxin may be an increased secretion of endogenous anti-neoplastic mediators and activation of the toll-like receptors (TLR). A detoxified endotoxin derivative, Monophosphoryl Lipid A (MPL(®)) is marketed in Europe since 1999 as part of the adjuvant systems in allergy vaccines for treatment of allergic rhino-conjunctivitis and allergic asthma. Over 200,000 patients have used them to date (nearly 70% in Germany). Since detailed exposure (MPL(®) dose and timing of administration) and individual data are potentially available, an observational follow-up study could be conducted in Germany to investigate the protective effect of MPL(®) against cancer, comparing cancer incidence in two groups of patients with allergic rhinitis: those treated with allergoids plus MPL(®) and those treated with a vaccine including the same allergoids but not MPL(®). The protective effect of MPL(®) could be quantified in ever and never smokers. If this proposed observational study provides evidence of protective effects, MPL(®) could be immediately used as a chemo-preventive agent since it is already in use as adjuvant in human vaccines against cancer.

  10. Metformin for aging and cancer prevention

    2010-01-01

    Studies in mammals have led to the suggestion that hyperglycemia and hyperinsulinemia are important factors in aging. Insulin/insulin-like growth factor 1 (IGF-1) signaling molecules that have been linked to longevity include daf-2 and InR and their homologues in mammals, and inactivation of the corresponding genes increases life span in nematodes, fruit flies and mice. It is possible that the life-prolonging effect of caloric restriction is due to decreasing IGF-1 levels. Evidence has emerged that antidiabetic drugs are promising candidates for both life span extension and prevention of cancer. Thus, antidiabetic drugs postpone spontaneous carcinogenesis in mice and rats, as well as chemical and radiation carcinogenesis in mice, rats and hamsters. Furthermore metformin seems to decrease cancer risk in diabetic patients. PMID:21084729

    The Latino/a Research & Policy Center (LRPC), at the University of Colorado (UC) at Denver and Health Sciences Center built the Greater Denver Latino Cancer Prevention Network, a successful cancer prevention network, in 6 Denver metro area counties. The Network consisted of 23 Latino community-based organizations, health clinics, social service agencies, faith-based groups, and employee-based organizations; 2 migrant health clinics; and 14 scientific partners including the UC Comprehensive Cancer Center, the Colorado Department of Public Health and Environment, and the American Cancer Society. The Network focused on 5 significant cancers: breast, cervical, lung, colorectal, and prostate cancer. The Steering Committee initiated a review process for junior researchers that resulted in 5 NCI-funded pilot projects. Pilot projects were conducted with various Latino populations. The Network developed community education and health promotion projects including the bilingual outreach play The Cancer Monologues. The Network's partnership also started and held 2 annual health fairs, Dia de la Mujer Latina/Day of the Latina Woman, and annual health prevention summits. The Special Population Network (SPN) adapted and revised a clinical trials education outreach module that reached Network community partners. SPN partners recruited Latino/a students to cancer research through a6-week NCI training program held yearly at the UCHSC campus. The Network methodology of bringing together the Latino community with the scientific community increased the level of awareness of cancer in the Latino community and increased cancer research and the level of engagement of the scientific partners with the Latino community.

    Recognizing the disparities in cancer morbidity and mortality that exist between African Americans and whites, an urban university and its neighborhood community undertook the development of an education program to transfer state-of-the-art cancer prevention, detection, and treatment information from an academic medical center to community residents, including school-age children. An intergenerational, multilevel intervention was developed to: 1) assess the health beliefs of the community, 2) identify, develop, and train an intergenerational group of community residents who would serve as health educators, and 3) promote behavioral change among the target population. Ten community residents were trained as educators. Over the course of two years they conducted cancer education programs that reached 775 adults. During the same period, the school-based educational intervention reached 264 seventh-grade students. Implications for the design and implementation of community-based cancer education programs in this African American community are identified.

    Gastric cancer continues to be an important healthcare problem from a global perspective. Most of the cases in the Western world are diagnosed at late stages when the treatment is largely ineffective. Helicobacter pylori (H. pylori) infection is a well-established carcinogen for gastric cancer. While lifestyle factors are important, the efficacy of interventions in their modification, as in the use of antioxidant supplements, is unconvincing. No organized screening programs can be found outside Asia (Japan and South Korea). Although several screening approaches have been proposed, including indirect atrophy detection by measuring pepsinogen in the circulation, none of them have so far been implemented, and more study data is required to justify any implementation. Mass eradication of H. pylori in high-risk areas tends to be cost-effective, but its adverse effects and resistance remain a concern. Searches for new screening biomarkers, including microRNA and cancer-autoantibody panels, as well as detection of volatile organic compounds in the breath, are in progress. Endoscopy with a proper biopsy follow-up remains the standard for early detection of cancer and related premalignant lesions. At the same time, new advanced high-resolution endoscopic technologies are showing promising results with respect to diagnosing mucosal lesions visually and targeting each biopsy. New histological risk stratifications (classifications), including OLGA and OLGIM, have recently been developed. This review addresses the current means for gastric cancer primary and secondary prevention, the available and emerging methods for screening, and new developments in endoscopic detection of early lesions of the stomach.

    The incidence and mortality of breast cancer is in an increasing trend. In contrast to the global breast cancer situation, the prevention and control is challenging in China. Some suggestions are presented to the project of breast cancer prevention and control in China. Combining the global screening experiences with the epidemiological features of Chinese female breast cancer, aims to improve the population screening and early detection rate. Standardizing clinical diagnosis and treatment practice, aims to increase the efficacy and decrease the mortality. Intervening lifestyle and dietary behaviors, and intends to reduce risk exposure and incidence. Building national breast cancer registry provides preventive strategies. Great efforts should be made to carry out large sample multicenter clinical trails and translational research on the prevention and cotrol of breast cancer coordiated by health care service and science and technology administrations. Breast cancer prevention and control has a long way to go in China.

    2010-08-01

    The fact that colorectal cancer (CRC) is the second leading cause of cancer mortality in the United States emphasizes the need for more effective preventive and therapeutic modalities. There is growing evidence that vitamin D may reduce the incidence of CRC. Results of epidemiologic, in vitro, in vivo animal and clinical studies suggest that a low serum vitamin D level may be a serious risk factor for CRC and a high serum vitamin D level may reduce the risk of CRC. On a molecular level, vitamin D suppresses CRC development and growth by affecting cell proliferation, differentiation, apoptosis, and angiogenesis. Vitamin D insufficiency and CRC are common in the elderly population. Vitamin D insufficiency is simple to screen for and treatable with vitamin D supplementation. Serum 25-hydroxyvitamin D (calcidiol) is the best measure of vitamin D status and should be checked routinely for individuals with risk factors for CRC. Maintaining serum concentrations of calcidiol above 32 ng/ml (80 nmol/l) in individuals whose serum calcidiol level is low may help prevent CRC as well as osteoporosis, fractures, infections, and cardiovascular disease. Daily calcidiol intake of 1000 International Units can increase serum vitamin D to sufficient levels in most elderly persons and, based on available data, may substantially lower the incidence of CRC with minimal risks.

    Regarding cancer awareness, social media effectively promotes health and supports self-management. Given the diverse study designs, methodologies, and approaches of social media interventions in oncology, it is difficult to determine the effects of social media on cancer prevention and management. We aim to systematically review intervention studies using social media for cancer care. A systematic search, using 7 electronic databases (PubMed, Web of Science, CINAHL, Cochrane Library, Scopus, EMBASE, and PsycINFO), was conducted to identify surveys and interventions using contemporary social media tools with a focus on cancer. Of the 18 selected studies, 7 were randomized controlled trials. Most studies were conducted for all types of cancer, and some were conducted for breast cancer in the United States, with mostly white female participants. Facebook was the most frequently used platform. Most studies targeted healthy participants providing cancer prevention education. With social media platforms as part of a larger intervention, or the main component of interventions, interventions were overall feasible and showed a significant improvement in cancer prevention and management. Social media tools have the potential to be effective in delivering interventions for cancer prevention and management. However, there was a dearth of studies with rigorous study methodologies to test social media effects on various cancer-related clinical outcomes. Social media use in cancer care will facilitate improved communication and support among patients, caregivers, and clinicians and, ultimately, improved patient care. Clinicians need to carefully harness social media to enhance patient care and clinical outcomes.

The purpose of this study was to determine whether prevention representations vary by cancer type (colon, lung, and skin cancer and whether representations are associated with relevant behaviors.MethodsWe analyzed data from the Health Information National Trends Survey (HINTS 2005, a nationally representative survey of American adults (N = 5,586 conducted by telephone interview.ResultsRespondents reported that all 3 types of cancer can be prevented through healthy behaviors; however, fewer did so for colon cancer. More respondents reported screening as a prevention strategy for colon cancer than did so for lung or skin cancer. Representations were associated with colon cancer screening, smoking status, and sunscreen use.ConclusionRepresentations of cancer were associated with relevant health behaviors, providing a target for health messages and interventions.

    This article provides the findings of a survey of previous and current students in the UDC/GU-LCCC master's degree program. This master's degree program, Cancer Biology, Prevention, and Control is administered and taught jointly by faculty of a Minority Serving Institution, the University of the District of Columbia, and the Lombardi Comprehensive Cancer Center to incorporate the strengths of a community-based school with a research intensive medical center. The program was initiated in 2008 through agreements with both University administrations and funding from the National Cancer Institute. The master's degree program is 36 credits with a focus on coursework in biostatistics, epidemiology, tumor biology, cancer prevention, medical ethics, and cancer outreach program design. For two semesters during the second year, students work full-time with a faculty person on a laboratory or outreach project that is a requirement for graduation. Students are supported and encouraged to transition to a doctoral degree after they obtain the master's and many of them are currently in doctorate programs. Since the inception of the program, 45 students have initiated the course of study, 28 have completed the program, and 13 are currently enrolled in the program. The survey was designed to track the students in their current activities, as well as determine which courses, program enhancements, and research experiences were the least and most useful, and to discern students' perceptions of knowledge acquired on various aspects of Cancer Biology Prevention, and Control Master's Program. Thirty of the 35 individuals to whom email requests were sent responded to the survey, for a response rate of 85.7%. The results of this study will inform the strengthening of the Cancer Biology program by the Education Advisory Committee. They can also be used in the development of comparable collaborative master's degree programs designed to address the significant disparities in prevalence of

  10. Selenium and Prostate Cancer Prevention: Insights from the Selenium and Vitamin E Cancer Prevention Trial (SELECT

    Full Text Available The Selenium and Vitamin E Cancer Prevention Trial (SELECT was conducted to assess the efficacy of selenium and vitamin E alone, and in combination, on the incidence of prostate cancer. This randomized, double-blind, placebo-controlled, 2 × 2 factorial design clinical trial found that neither selenium nor vitamin E reduced the incidence of prostate cancer after seven years and that vitamin E was associated with a 17% increased risk of prostate cancer compared to placebo. The null result was surprising given the strong preclinical and clinical evidence suggesting chemopreventive activity of selenium. Potential explanations for the null findings include the agent formulation and dose, the characteristics of the cohort, and the study design. It is likely that only specific subpopulations may benefit from selenium supplementation; therefore, future studies should consider the baseline selenium status of the participants, age of the cohort, and genotype of specific selenoproteins, among other characteristics, in order to determine the activity of selenium in cancer prevention.

    Full Text Available Background and objective It has been proven that increase of the awareness level of lung cancer prevention and control could enhance participation of lung cancer screening of lung cancer high risk group. The aim of this study is to investigate the awareness level of lung cancer prevention and control and the effect of individual characteristics on lung cancer awareness, and to provide evidence for comprehensive lung cancer prevention in high risk areas of lung cancer. Methods Staffs of Tianjin Dagang Oil Field who participate low dose CT (LDCT lung cancer screening by cluster sampling or according to voluntary principle were surveyed, data of lung cancer awareness were collected by questionnaire. Results A total of 1,633 valid questionnaires were collected. The average age of respondents was 60.08±6.58. Most participants were males (82.2% while female only accounted for 17.8%. The proportions of awareness about lung cancer in China, risk factors, screening methods and the knowledge of health examination were 64.5%, 77.1%, 43.7%, 49.6% respectively. Result of multiple logistic regression analysis showed that education level, smoking (pack-year, age, prior tuberculosis were the influencing factors of lung cancer awareness with adjusted Ors for education and age level as of 0.567 (95%CI: 0.439-0.733 and 1.373 (95%CI: 1.084-1.739 respectively. 80.3% of the participants can accept health examination once a year, while the ability to pay the medical expenses was not high. The influencing factors of health examination willingness were gender, age, income, the knowledge of lung cancer. Conclusion Education level and smoking affect the awareness of lung cancer prevention and control, health education for lung cancer should be conducted especially in population with low education level. Comprehensive lung cancer control in high risk areas should combined lung cancer screening, tobacco control and health education.

  16. The war on prevention: bellicose cancer metaphors hurt (some) prevention intentions.

    Science.gov (United States)

    Hauser, David J; Schwarz, Norbert

    2015-01-01

    Cancer health information is dominated by enemy and war metaphors intended to motivate the public to "fight" cancer. However, enemy metaphoric framing may influence understanding of, and responses to, cancer. Cancer prevention benefits from avoiding risk increasing behaviors, yet self-limitation is not closely associated with fighting enemies. If so, the metaphor may hurt prevention intentions involving self-limitation. Participants read messages with minute wording variations that established different metaphoric frames. Results show that metaphorically framing cancer as an enemy lessens the conceptual accessibility of (Study 1) and intention for self-limiting prevention behaviors while not increasing intention for monitoring and treatment behaviors (Studies 2 and 3). Framing self-limiting prevention behaviors in terms of fighting an enemy increases their appeal, illustrating the benefits of metaphor matching (Study 3). Overall, these results suggest that enemy metaphors in cancer information reduce some prevention intentions without increasing others, making their use potentially harmful for public health.

  17. Vitamin D and prevention of breast cancer

    JoEllen WELSH

    2007-01-01

    Epidemiologic data have demonstrated that breast cancer incidence is inversely correlated with indices of vitamin D status, including ultraviolet exposure, which enhances epidermal vitamin D synthesis. The vitamin D receptor (VDR) is ex-pressed in mammary epithelial cells, suggesting that vitamin D may directly influ-ence sensitivity of the gland to transformation. Consistent with this concept, in vitro studies have demonstrated that the VDR ligand, 1,25-dihydroxyvitamin D (1,25D), exerts negative growth regulatory effects on mammary epithelial ceils that contribute to maintenance of the differentiated phenotype. Furthermore, deletion of the VDR gene in mice alters the balance between proliferation and apoptosis in the mammary gland, which ultimately enhances its susceptibility to carcinogenesis.In addition, dietary supplementation with vitamin D, or chronic treatment with synthetic VDR agonists, reduces the incidence of carcinogen-induced mammary tumors in rodents. Collectively, these observations have reinforced the need to further define the human requirement for vitamin D and the molecular actions of the VDR in relation to prevention of breast cancer.

    As trauma is a public health problem, different programs have been designed to prevent injuries. The aim of this study was to evaluate the effectiveness of an educational model that measures the adolescents' attitudes towards the rules of road safety, alcohol and road accidents in Colombia. A pedagogical model evaluating the effect of road safety education and adolescents' attitudes towards and experiences of alcohol and road accidents in Colombia was created. After the education concluded, this educational process is analyzed by its impact on adolescents' behavior. The educational program included 160 adolescents with the mean age being 17.5 years. The test results indicated that before the educational program 80% of adolescents did not use a safety element when driving, while after the educational program the percentage of no helmet use among adolescents decreased from 72.5% to 24.3% (p = 0.0001) and driving a vehicle under the state of drunkenness from 49.3% to 8.1% (p = 0.0001). An educational model aimed at preventing injuries caused by traffic accidents is shown to be effective in generating changes in adolescents' customs of and attitudes towards alcohol and road safety standards in Colombia.

    Picconi, María Alejandra

    2013-01-01

    Cervical cancer (CC), which is strongly associated to high-risk human papillomavirus (hr-HPV) infection, continues being a significant health problem in Latin America. The use of conventional cytology to detect precancerous cervical lesions has had no major impact on reducing CC incidence and mortality rates, which are still high in the region. New screening tools to detect precancerous lesions became available, which provide great opportunities for CC prevention, as do highly efficacious HPV vaccines able to prevent nearly all lesions associated with HPV-16 and -18 when applied before viral exposure. Currently, hr-HPV testing represents an invaluable component of clinical guidelines for screening, management and treatment of CC and their precursor lesions. Many testing strategies have been developed that can detect a broad spectrum of hr-HPV types in a single assay; however, only a small subset of them has documented clinical performance for any of the standard HPV testing indications. HPV tests that have not been validated and lack proof of reliability, reproducibility and accuracy should not be used in clinical management. Once incorporated into the lab, it is essential to submit the whole procedure of HPV testing to continuous and rigorous quality assurance to avoid sub-optimal, potentially harmful practices. Recent progress and current status of these methods are discussed in this article.

    Cervical cancer is the second most common female tumor worldwide, and its incidence is disproportionately high (>80%) in the developing world. In the United States, in which Papanicolaou (Pap) tests have reduced the annual incidence to approximately 11,000 cervical cancers, >60% of cases are reported to occur in medically underserved populations as part of a complex of diseases linked to poverty, race/ethnicity, and/or health disparities. Because carcinogenic human papillomavirus (HPV) infections cause virtually all cervical cancer, 2 new approaches for cervical cancer prevention have emerged: 1) HPV vaccination to prevent infections in younger women (aged or =30 years). Together, HPV vaccination and testing, if used in an age-appropriate manner, have the potential to transform cervical cancer prevention, particularly among underserved populations. Nevertheless, significant barriers of access, acceptability, and adoption to any cervical cancer prevention strategy remain. Without understanding and addressing these obstacles, these promising new tools for cervical cancer prevention may be futile. In the current study, the delivery of cervical cancer prevention strategies to these US populations that experience a high cervical cancer burden (African-American women in South Carolina, Alabama, and Mississippi; Haitian immigrant women in Miami; Hispanic women in the US-Mexico Border; Sioux/Native American women in the Northern Plains; white women in the Appalachia; and Vietnamese-American women in Pennsylvania and New Jersey) is reviewed. The goal was to inform future research and outreach efforts to reduce the burden of cervical cancer in underserved populations.

    The University of the District of Columbia (UDC) and the Lombardi Comprehensive Cancer Center (LCCC), Georgetown University Medical Center established a Masters Degree Program in Cancer Biology, Prevention and Control at UDC that is jointly administered and taught by UDC and LCCC faculty. The goal of the Masters Degree Program is to educate students as master-level cancer professionals capable of conducting research and service in cancer biology, prevention, and control or to further advance the education of students to pursue doctoral studies. The Program's unique nature is reflected in its philosophy "the best cancer prevention and control researchers are those with a sound understanding of cancer biology". This program is a full-time, 2-year, 36-credit degree in which students take half of their coursework at UDC and half of their coursework at LCCC. During the second year, students are required to conduct research either at LCCC or UDC. Unlike most cancer biology programs, this unique Program emphasizes both cancer biology and cancer outreach training.

    Purpose To assist in determining barriers to an oncology career incorporating cancer prevention, the American Society of Clinical Oncology (ASCO) Cancer Prevention Workforce Pipeline Work Group sponsored surveys of training program directors and oncology fellows. Methods Separate surveys with parallel questions were administered to training program directors at their fall 2013 retreat and to oncology fellows as part of their February 2014 in-training examination survey. Forty-seven (67%) of 70 training directors and 1,306 (80%) of 1,634 oncology fellows taking the in-training examination survey answered questions. Results Training directors estimated that ≤ 10% of fellows starting an academic career or entering private practice would have a career focus in cancer prevention. Only 15% of fellows indicated they would likely be interested in cancer prevention as a career focus, although only 12% thought prevention was unimportant relative to treatment. Top fellow-listed barriers to an academic career were difficulty in obtaining funding and lower compensation. Additional barriers to an academic career with a prevention focus included unclear career model, lack of clinical mentors, lack of clinical training opportunities, and concerns about reimbursement. Conclusion Reluctance to incorporate cancer prevention into an oncology career seems to stem from lack of mentors and exposure during training, unclear career path, and uncertainty regarding reimbursement. Suggested approaches to begin to remedy this problem include: 1) more ASCO-led and other prevention educational resources for fellows, training directors, and practicing oncologists; 2) an increase in funded training and clinical research opportunities, including reintroduction of the R25T award; 3) an increase in the prevention content of accrediting examinations for clinical oncologists; and 4) interaction with policymakers to broaden the scope and depth of reimbursement for prevention counseling and

    The links between nutrition and cancer onset are now well established by epidemiological studies. The scientific evidence is presented in a report of the World Cancer Research Foundation (WCRF). Protective factors towards overall cancer risk are fruit and vegetable consumption and physical activity. Overweight and obesity, intakes of alcoholic beverage, fat, salt, high temperature cooked and processed red meat, increase cancer risk. In addition, beta-carotene systematic supplementation could increase lung cancer risk in smokers. As optimal controlling of these risk factors can decrease cancer mortality by 25%, nutritional counselling must be integrated in the global strategy of primary and secondary prevention of cancers.

    Vitamins are a class of organic compounds that are components of an adequate diet. They or their derivatives function as coenzymes, cellular antioxidants, and/or regulators of gene expression. Fourteen vitamins are recognized in human nutrition (Vitamins A, D, E, K, B1, B2, B6, B12, C, niacin, folacin, pantothenic acid, biotin, choline), with deficiencies or excesses in intake leading to changes in protein, nucleic acid, carbohydrates, fat and/or mineral metabolism. Thus, the integrity of physiological systems, including those associated with detoxification, cellular repair, immune processes, and neural and endocrine function, depends upon the nutritional and vitamin status of the host. For these reasons, it may be anticipated that the adequacy of the vitamin supply to cells and tissues would affect the development, progress, and outcome of cancers. In this review, the definition and functions of and requirements and recommended allowance for vitamins are discussed briefly before exploring the evidence, largely from studies in experimental animals, that indicates the nature of the link between vitamins and cancer. Although evidence based on studies in animal systems reveals that vitamin intake and status can modulate the outcome of experimental carcinogenesis, the findings are often conflicting and difficult to interpret. Furthermore, it is not yet possible to develop a suitable prediction of the role of the individual vitamins in tumor development. The significance of these observations for human nutrition and cancer prevention, particularly in reference to ascorbic acid (vitamin C), vitamin E, and B-complex vitamins is considered. Vitamin A and retinoid compounds are discussed elsewhere in the symposium. The many popular misconceptions and unsound advice concerning vitamins and health, including "fake" vitamins-pangamic acid ("vitamin B15") and laetrile ("vitamin B17")-are also discussed. On the basis of current evidence, it would be inappropriate to recommend

    Cervical cancer is a preventable disease with a known etiology (human papillomavirus), effective preventive vaccines, excellent screening methods, and a treatable pre-invasive phase. Surgery is the primary treatment for pre-invasive and early-stage disease and can safely be performed in many low-resource settings. However, cervical cancer rates remain high in many areas of Latin America. This article presents a number of evidence-based strategies being implemented to improve cervical cancer outcomes in Latin America.

    Colorectal cancer (CRC) is a very heterogeneous disease that is caused by the interaction of genetic and environmental factors. CRC develops through a gradual accumulation of genetic and epigenetic changes, leading to the transformation of normal colonic mucosa into invasive cancer. CRC is one of the most prevalent and incident cancers worldwide, as well as one of the most deadly. Approximately 1235108 people are diagnosed annually with CRC, and 609051 die from CRC annually. The World Health Organization estimates an increase of 77% in the number of newly diagnosed cases of CRC and an increase of 80% in deaths from CRC by 2030. The incidence of CRC can benefit from different strategies depending on its stage: health promotion through health education campaigns (when the disease is not yet present), the implementation of screening programs (for detection of the disease in its early stages), and the development of nearly personalized treatments according to both patient characteristics (age, sex) and the cancer itself (gene expression). Although there are different strategies for screening and although the number of such strategies is increasing due to the potential of emerging technologies in molecular marker application, not all strategies meet the criteria required for screening tests in population programs; the three most accepted tests are the fecal occult blood test (FOBT), colonoscopy and sigmoidoscopy. FOBT is the most used method for CRC screening worldwide and is also the primary choice in most population-based screening programs in Europe. Due to its non-invasive nature and low cost, it is one of the most accepted techniques by population. CRC is a very heterogeneous disease, and with a few exceptions (APC, p53, KRAS), most of the genes involved in CRC are observed in a small percentage of cases. The design of genetic and epigenetic marker panels that are able to provide maximum coverage in the diagnosis of colorectal neoplasia seems a reasonable strategy

    The environment is an underutilized pathway to breast cancer prevention. Current research approaches and funding streams related to breast cancer and the environment are unequal to the task at hand. We undertook the California Breast Cancer Prevention Initiatives, a four-year comprehensive effort to set a research agenda related to breast cancer, the environment, disparities and prevention. We identified 20 topics for Concept Proposals reflecting a life-course approach and the complex etiology of breast cancer; considering the environment as chemical, physical and socially constructed exposures that are experienced concurrently: at home, in the community and at work; and addressing how we should be modifying the world around us to promote a less carcinogenic environment. Redirecting breast cancer research toward prevention-oriented discovery could significantly reduce the incidence and associated disparities of the disease among future generations.

  15. PREVENTING THE CHROMOSOMAL TRANSLOCATIONS THAT CAUSE CANCER.

    Approximately half of all cancers harbor chromosomal translocations that can either contribute to their origin or govern their subsequent behavior. Chromosomal translocations by definition can only occur when there are two DNA double-strand breaks (DSBs) on distinct chromosomes that are repaired heterologously. Thus, chromosomal translocations are by their very nature problems of DNA DSB repair. Such DNA DSBs can be from internal or external sources. Internal sources of DNA DSBs that can lead to translocations can occur are inappropriate immune receptor gene maturation during V(D)J recombination or heavy-chain switching. Other internal DNA DSBs can come from aberrant DNA structures, or are generated at collapsed and reversed replication forks. External sources of DNA DSBs that can generate chromosomal translocations are ionizing radiation and cancer chemotherapy. There are several known nuclear and chromatin properties that enhance translocations over homologous chromosome DSB repair. The proximity of the region of the heterologous chromosomes to each other increases translocation rates. Histone methylation events at the DSB also influence translocation frequencies. There are four DNA DSB repair pathways, but it appears that only one, alternative non-homologous end-joining (a-NHEJ) can mediate chromosomal translocations. The rate-limiting, initial step of a-NHEJ is the binding of poly-adenosine diphosphate ribose polymerase 1 (PARP1) to the DSB. In our investigation of methods for preventing oncogenic translocations, we discovered that PARP1 was required for translocations. Significantly, the clinically approved PARP1 inhibitors can block the formation of chromosomal translocations, raising the possibility for the first time that secondary oncogenic translocations can be reduced in high risk patients.

    The Alabama Department of Public Health (ADPH) is collaborating with the National Cancer Institute to develop detailed profiles of underserved Alabama communities most at risk for cancer. These profiles will be combined with geocoded data to create a pilot project, Cancer Prevention for Alabama's Underserved Populations: A Focused Approach. The project's objectives are to provide the ADPH's cancer prevention programs with a more accurate and cost-effective means of planning, implementing, and evaluating its prevention activities in an outcomes-oriented and population-appropriate manner. The project links geocoded data from the Alabama Statewide Cancer Registry with profiles generated by the National Cancer Institute's cancer profiling system, Consumer Health Profiles. These profiles have been successfully applied to market-focused cancer prevention messages across the United States. The ADPH and the National Cancer Institute will evaluate the efficacy of using geocoded data and lifestyle segmentation information in strategy development and program implementation. Alabama is the first state in the nation not only to link geocoded cancer registry data with lifestyle segmentation data but also to use the National Cancer Institute's profiles and methodology in combination with actual state data.

    Obesity is associated with increased risk and poor prognosis for many types of cancer. The mechanisms underlying the obesity-cancer link are becoming increasingly clear and provide multiple opportunities for primary to tertiary prevention. Several obesity-related host factors can influence tumor initiation, progression and/or response to therapy, and these have been implicated as key contributors to the complex effects of obesity on cancer incidence and outcomes. These host factors include insulin, insulin-like growth factor-1, leptin, adiponectin, steroid hormones, cytokines, and inflammation-related molecules. Each of these host factors is considered in the context of energy balance and as potential targets for cancer prevention. The possibility of prevention at the systems level, including energy restriction, dietary composition and exercise is considered as is the importance of the newly-emerging field of stem cell research as a model for studying energy balance and cancer prevention.

  2. Defining and targeting an audience for cancer-prevention messages.

    Science.gov (United States)

    Bettinghaus, E P

    1992-01-01

    The target audience for cancer-prevention messages is not the cancer patient. Cancer-prevention messages should be designed for and directed toward groups of people who have been determined to be at risk for the disease. Potential audiences may vary widely in size and nature, depending on the specific cancer, its cause, and its etiology. The prevention of specific disease, eg, lung cancer, typically demands some behavior on the part of the recipient of a cancer-prevention message. Thus, members of a target audience may be asked to stop smoking or to refrain from starting. Each potential target audience is likely to be unique and cannot always be reached with typical mass-media campaigns. Messages designed to be effective for such special audiences may be required if a significant impact on behavior is to be obtained. This article attempts to identify potential audiences for cancer-prevention messages and develops the nature of the media to be used, the sources to be employed, and the arguments to be developed in such a campaign. Characteristics (eg, sex, race, age, marital status, and socioeconomic status) are used as examples of variables that may dictate the nature of cancer-prevention campaigns.

    2014-11-01

    Cancer is a major disease worldwide and different approaches are needed for its prevention. Previous laboratory and clinical studies suggest that cancer can be prevented by chemicals, including those from the diet. Furthermore, epidemiological studies have suggested that deficiencies in certain nutrients can increase the risk of some cancers. In this article on chemo/dietary prevention, examples will be given to illustrate the effectiveness of chemopreventive agents in the prevention of breast, colon and prostate cancers in high-risk populations and the possible side effects of these agents. The potential usefulness of dietary approaches in cancer prevention and the reasons for some of the failed trials will be discussed. Lessons learned from these studies can be used to design more relevant research projects and develop effective measures for cancer prevention in the future. The development of effective chemopreventive agents, the use of nutrient supplements in deficient or carcinogen-exposed populations, and the importance of cohort studies will be discussed in the context of the current socioeconomic situation in China. More discussions are needed on how we can influence society to pay more attention to cancer prevention research and measures.

    Nanotechnology is emerging as a promising modality for cancer treatment; however, in the realm of cancer prevention, its full utility has yet to be determined. Here, we discuss the potential of integrating nanotechnology in cancer prevention to augment early diagnosis, precision targeting, and controlled release of chemopreventive agents, reduced toxicity, risk/response assessment, and personalized point-of-care monitoring. Cancer is a multistep, progressive disease; the functional and acquired characteristics of the early precancer phenotype are intrinsically different from those of a more advanced anaplastic or invasive malignancy. Therefore, applying nanotechnology to precancers is likely to be far more challenging than applying it to established disease. Frank cancers are more readily identifiable through imaging and biomarker and histopathologic assessment than their precancerous precursors. In addition, prevention subjects routinely have more rigorous intervention criteria than therapy subjects. Any nanopreventive agent developed to prevent sporadic cancers found in the general population must exhibit a very low risk of serious side effects. In contrast, a greater risk of side effects might be more acceptable in subjects at high risk for cancer. Using nanotechnology to prevent cancer is an aspirational goal, but clearly identifying the intermediate objectives and potential barriers is an essential first step in this exciting journey. ©2014 American Association for Cancer Research.

  6. Advancing cervical cancer prevention in India: implementation science priorities.

    Cervical cancer is the leading cause of cancer mortality in India, accounting for 17% of all cancer deaths among women aged 30 to 69 years. At current incidence rates, the annual burden of new cases in India is projected to increase to 225,000 by 2025, but there are few large-scale, organized cervical cancer prevention programs in the country. We conducted a review of the cervical cancer prevention research literature and programmatic experiences in India to summarize the current state of knowledge and practices and recommend research priorities to address the gap in services. We found that research and programs in India have demonstrated the feasibility and acceptability of cervical cancer prevention efforts and that screening strategies requiring minimal additional human resources and laboratory infrastructure can reduce morbidity and mortality. However, additional evidence generated through implementation science research is needed to ensure that cervical cancer prevention efforts have the desired impact and are cost-effective. Specifically, implementation science research is needed to understand individual- and community-level barriers to screening and diagnostic and treatment services; to improve health care worker performance; to strengthen links among screening, diagnosis, and treatment; and to determine optimal program design, outcomes, and costs. With a quarter of the global burden of cervical cancer in India, there is no better time than now to translate research findings to practice. Implementation science can help ensure that investments in cervical cancer prevention and control result in the greatest impact.

    The effectiveness of interventions for health promotion, protection, and early diagnosis may include the process of persuasion employed. This study aims to evaluate the risk level of developing cancer, considering the pertinent risk factors, and the presence of persuasion and characteristics in communication regarding cancer prevention and early detection. It is an observational study, conducted among 110 inhabitants of a neighborhood in Ribeirao Preto, Sao Paulo, Brazil. It was confirmed that there are high risks for colon/rectum, cervical, and endometrial cancer; and moderate risks for the above as well as lung and breast cancer. In terms of persuasion, it was observed that cancer information was spread but not sustained for long periods. Moreover, there was no reinforcement. In view of cancer risk and the identified preventive behaviors, persuasion is considered a useful strategy to reduce these risks, as well as to encourage and sustain preventive behaviors, since it indicates routes to be followed.

    Since the Iraq war began in 2003, over 4 million Iraqis have been displaced. Little is known about preventive cancer care in this population, but stark disparities have been documented. The purpose of this study was to assess the perspectives of Iraqi women refugees on preventive care and perceived barriers to breast cancer screening. Interviews were conducted in Arabic with twenty Iraqi refugee women by a bilingual (English/Arabic) medical student, transcribed, translated and coded according to established qualitative content and thematic analysis procedures. Psychosocial barriers, culturally mediated beliefs, and health consequences of war were identified as major themes, ultimately showing what factors, alone and collectively, have impeded Iraqi refugee women's ability and motivation to obtain breast cancer screening. To improve cancer prevention and decrease disparities in care in this most vulnerable population, culturally appropriate health education and outreach programs, as well as further community-level targeted studies, are needed.

  9. Impact of preventive therapy on the risk of breast cancer among women with benign breast disease.

    There are three main ways in which women can be identified as being at high risk of breast cancer i) family history of breast and/or ovarian cancer, which includes genetic factors ii) mammographically identified high breast density, and iii) certain types of benign breast disease. The last category is the least common, but in some ways the easiest one for which treatment can be offered, because these women have already entered into the treatment system. The highest risk is seen in women with lobular carcinoma in situ (LCIS), but this is very rare. More common is atypical hyperplasia (AH), which carries a 4-5-fold risk of breast cancer as compared to general population. Even more common is hyperplasia of the usual type and carries a roughly two-fold increased risk. Women with aspirated cysts are also at increased risk of subsequent breast cancer. Tamoxifen has been shown to be particularly effective in preventing subsequent breast cancer in women with AH, with a more than 70% reduction in the P1 trial and a 60% reduction in IBIS-I. The aromatase inhibitors (AIs) also are highly effective for AH and LCIS. There are no published data on the effectiveness of tamoxifen or the AIs for breast cancer prevention in women with hyperplasia of the usual type, or for women with aspirated cysts. Improving diagnostic consistency, breast cancer risk prediction and education of physicians and patients regarding therapeutic prevention in women with benign breast disease may strengthen breast cancer prevention efforts.

  10. Innovation in cervical cancer prevention and control in Mexico.

    Science.gov (United States)

    Lazcano-Ponce, Eduardo; Allen-Leigh, Betania

    2009-08-01

    Disparities related to cervical cancer continue to exist in Mexico, including insufficient screening coverage, problems with quality control and a resulting greater risk of mortality among women from marginalized areas. A lack of opportunities and requirements for continuing education and accreditation of healthcare personnel involved in the screening program is also an issue. HPV DNA testing and HPV vaccines are recent technological innovations that offer a potential solution to the continued negative impact of cervical cancer among Mexican women. This essay attempts to answer questions such as: Why should HPV testing be integrated into the early detection program in Mexico? How can HPV testing best be integrated into the program in Mexico? How-from a public health perspective that seeks to reduce disparities-can HPV vaccination best be implemented in Mexico? HPV testing allows increased positive predictive value while also reducing costly and unnecessary overtreatment of low-grade abnormalities, and HPV vaccines offer the possibility of primary prevention of cervical cancer. The strategy proposed for Mexico includes primary prevention with HPV vaccination for girls aged between 12 and 16 years (before sexual initiation), Pap testing with excellent quality control for women 24-34 years of age and high-risk HPV DNA testing for women 35 years and older. HPV samples would be either clinically collected or self-collected and women with positive HPV test results would receive follow-up high-quality Pap testing. This approach is creative and focuses on reducing disparities and providing high-quality care that is also cost effective.

    Health promotion programs designed to address colorectal cancer disparities among African Americans are increasing. Unfortunately, this group still shoulders a disproportionate mortality burden in the United States; these numbers are also reflective of colorectal cancer (CRC) disparities in the Midwest. The purpose of this study was to extrapolate results from in-depth interviews and brief surveys on the effectiveness of the church as a social marketer of CRC-prevention messages. Results show that pastors believe the congregation has limited knowledge about CRC risk and prevention; they also believe the church can improve cancer-prevention communication among members and those affiliated with the church.

  12. Complementary roles in cancer prevention: protease inhibitor makes the cancer preventive peptide lunasin bioavailable.

    Directory of Open Access Journals (Sweden)

    Chia-Chien Hsieh

    Full Text Available BACKGROUND: The lower incidence of breast cancer among Asian women compared with Western countries has been partly attributed to soy in the Asian diet, leading to efforts to identify the bioactive components that are responsible. Soy Bowman Birk Inhibitor Concentrate (BBIC is a known cancer preventive agent now in human clinical trials. METHODOLOGY/PRINCIPAL FINDINGS: The objectives of this work are to establish the presence and delineate the in vitro activity of lunasin and BBI found in BBIC, and study their bioavailability after oral administration to mice and rats. We report that lunasin and BBI are the two main bioactive ingredients of BBIC based on inhibition of foci formation, lunasin being more efficacious than BBI on an equimolar basis. BBI and soy Kunitz Trypsin Inhibitor protect lunasin from in vitro digestion with pancreatin. Oral administration of (3H-labeled lunasin with lunasin-enriched soy results in 30% of the peptide reaching target tissues in an intact and bioactive form. In a xenograft model of nude mice transplanted with human breast cancer MDA-MB-231 cells, intraperitoneal injections of lunasin, at 20 mg/kg and 4 mg/kg body weight, decrease tumor incidence by 49% and 33%, respectively, compared with the vehicle-treated group. In contrast, injection with BBI at 20 mg/kg body weight shows no effect on tumor incidence. Tumor generation is significantly reduced with the two doses of lunasin, while BBI is ineffective. Lunasin inhibits cell proliferation and induces cell death in the breast tumor sections. CONCLUSIONS/SIGNIFICANCE: We conclude that lunasin is actually the bioactive cancer preventive agent in BBIC, and BBI simply protects lunasin from digestion when soybean and other seed foods are eaten by humans.

    2014-01-01

    Skin cancer is the most frequent type of cancer in white population worldwide. However, because the most prominent risk factor-solar UV-radiation and/or artificial UV from sunbeds-is known, skin cancer is highly preventable be primary prevention. This prevention needs, that the public is informed by simple and balanced messages about the possible harms and benefits of UV-exposure and how a person should behave under certain conditions of UV-exposure. For this purpose information and recommendations for the public must be age- and target-group specific to cover all periods of life and to reach all sub-groups of a population, continuously. There is a need that political institutions together with Health Institutions and Societies (e.g., European Commission, WHO, EUROSKIN, ICNIRP, etc.), which are responsible for primary prevention of skin cancer, find a common language to inform the public, in order not to confuse it. This is especially important in connection with the ongoing Vitamin D debate, where possible positive effects of UV have to be balanced with the well known skin cancer risk of UV. A continuously ongoing evaluation of interventions and programs in primary prevention is a pre-requisite to assess the effectiveness of strategies. There is surely no "no message fits all" approach, but balanced information in health initiatives for prevention of skin cancer, which use evidence-base strategies, will further be needed in the future to reduce the incidence, morbidity and mortality skin cancer.

    The Division of Cancer Prevention (DCP) conducts and supports research to determine a person's risk of cancer and to find ways to reduce the risk. This knowledge is critical to making progress against cancer because risk varies over the lifespan as genetic and epigenetic changes can transform healthy tissue into invasive cancer.

    Current estimates from the American Cancer Society and from the International Union Against Cancer indicate that 12 million cases of cancer were diagnosed last year, with 7 million deaths worldwide; these numbers are expected to double by 2030 (27 million cases with 17 million deaths). Despite tremendous technological developments in all areas, and President Richard Nixon's initiative in the 1974 "War against Cancer", the US cancer incidence is the highest in the world and the cancer death rate has not significantly changed in the last 50 years (193.9 per 100,000 in 1950 vs 193.4 per 100,000 in 2002). Extensive research during the same time, however, has revealed that cancer is a preventable disease that requires major changes in life style; with one third of all cancers assigned to Tobacco, one third to diet, and remaining one third to the environment. Approximately 20 billion dollars are spent annually to find a cure for cancer. We propose that our inability to find a cure to cancer lies in the models used. Whether cell culture or animal studies, no model has yet been found that can reproduce the pathogenesis of the disease in the laboratory. Mono-targeted therapies, till know in most cases, have done a little to make a difference in cancer treatment. Similarly, molecular signatures/predictors of the diagnosis of the disease and response are also lacking. This review discusses the pros and cons of current cancer models based on cancer genetics, cell culture, animal models, cancer biomarkers/signature, cancer stem cells, cancer cell signaling, targeted therapies, therapeutic targets, clinical trials, cancer prevention, personalized medicine, and off-label uses to find a cure for cancer and demonstrates an urgent need for "out of the box" approaches.

    Full Text Available Cancer is a chronic disease and the prevalence is increasing at a faster rate in recent years. Most of the cancers are incurable, treatment is very expensive and is not affordable even for above middle-class people. A strong correlation is observed between lifestyle factors and cancer incidence or prevention. Let us know about cancer prevention lifestyle focussing mainly on the role of physical activity and diet. Most of the people leading sedentary life style. There is an overall decline in the level of physical activity. There is strong evidence between adequate physical activity and prevention of colon cancer and breast cancer. Regular and proper physical activity increases the motility of digestive system and decreases the residence time of food carcinogens. Further it will decrease obesity as well as abdominal fat deposition. Moreover regular physical activity is associated with a decrease in the circulating levels of sex hormones, insulin and insulin like growth factor; all are associated with cancer incidence. Let us be active to make world cancer free. Meet you again in the next issue with the role of diet in cancer prevention.

    The goals of any cervical cancer prevention program should be threefold: to achieve high coverage of the population at risk, to screen women with an accurate test as part of high-quality services, and to ensure that women with positive test results are properly managed. This article focuses on the experiences of the Alliance for Cervical Cancer Prevention (ACCP) in delivery of screening and treatment services as part of cervical cancer prevention projects in Africa, Latin America, and Asia. Research and experience show that cervical cancer can be prevented when strategies and services are well planned and well managed and when attention is paid to program monitoring and evaluation. Coordination of program components, reduction of the number of visits, improvement of service quality, and flexibility in how services are delivered are all essential features of an effective service.

    Cervical cancer is the second most common female cancer after breast cancer both in Malaysia and worldwide although it can be mostly prevented. The objective of this study was to assess the knowledge level and attitude of University Kebangsaan Malaysia female students in the Faculties of Pharmacy and Allied Health Sciences on the prevention of cervical cancer. A total of 675 respondents were recruited for this cross-sectional study involving pre-tested questionnaires. The data was analyzed using Statistical Package for Social Sciences (SPSS) version 15.0. There was significant association between grade and mean score of knowledge with different faculties and year of education (pknowledge with different programs in the Faculty of Allied Health Sciences. For mean score of knowledge, significant difference only existed among different races (pknowledge level of respondents on cervical cancer and its prevention was not satisfactory despite their positive attitude on prevention. Thus, more awareness programs should be conducted in University campuses to provide students with knowledge on prevention of cervical cancer.

    Colorectal cancer is one of the leading causes of cancer-related deaths in the United States, and generally, as countries climb the economic ladder, their rates of colon cancer increase. Colon cancer was an early disease where key genetic mutations were identified as important in disease progression, and there is considerable interest in determining whether specific mutations sensitize the colon to cancer prevention strategies. Epidemiological studies have revealed that fiber- and vegetable-rich diets and physical activity are associated with reduced rates of colon cancer, while consumption of red and processed meat, or alcoholic beverages, and overconsumption as reflected in obesity are associated with increased rates. Animal studies have probed these effects and suggested directions for further refinement of diet in colon cancer prevention. Recently a central role for the microorganisms in the gastrointestinal tract in colon cancer development is being probed, and it is hypothesized that the microbes may integrate diet and host genetics in the etiology of the disease. This review provides background on dietary, genetic, and microbial impacts on colon cancer and describes an ongoing project using rodent models to assess the ability of digestion-resistant starch in the integration of these factors with the goal of furthering colon cancer prevention.

    Nutritional status and healthy lifestyle are important factors not only in cancer etiology but also for prevention efforts. A good nutritional status contributes to a healthy life with high economic, social and cultural level. Unhealthy eating habits are part of risky behavior seen from adolescence. The present study was therefore carried out to determine eating habits, level of knowledge about cancer prevention and behavior of a group of adolescents. Data were collected using questionnaire covering eating habits and knowledge of adolescents on prevention from cancer, and special scale (HPLP) to determine the related behavior. Three hundred sixty six of 390 students volunteered for study. Eating habits and the level of cancer prevention knowledge were similar for both genders, except for the exercise issue. The mean total points of adolescents in the Health Promotion Behavior and Subscales was 113,63. While spiritual growth had the highest score in HPLP subscale, exercise had a minimal score. Exercise was the only HPLP subscale with a statistically significant difference between male and female genders. Although they have some information, the adolescents surveyed did not have preventive skills relative to their practical life. In general in order to ensure cancer prevention and a healthy life style social, cultural and sportive activities should be encouraged and educational programmes supporting these goals should be designed and applied for all stages of life, starting in early childhood.

    Cervical cancer is the second most common female tumor worldwide and its incidence is disproportionately high (>80%) in the developing world. In the U.S., where Pap tests have reduced the annual incidence to approximately 11,000 cervical cancers, more than 60% of cases occur in medically-underserved populations as part of a complex of diseases linked to poverty, race/ethnicity, and/or health disparities. Because carcinogenic human papillomavirus (HPV) infections cause virtually all cervical cancer, two new approaches for cervical cancer prevention have emerged: 1) HPV vaccination to prevent infections in younger women (≤18 years old) and 2) carcinogenic HPV detection in older women (≥30 years old). Together, HPV vaccination and testing, if used in an age-appropriate manner, have the potential to transform cervical cancer prevention particularly among underserved populations. Yet significant barriers of access, acceptability, and adoption to any cervical cancer prevention strategy remain. Without understanding and addressing these obstacles, these promising new tools for cervical cancer prevention may be futile. We share our experiences in the delivery of cervical cancer prevention strategies to U.S. populations experiencing high cervical cancer burden: African-American women in South Carolina, Alabama, Mississippi; Haitian immigrant women in Miami; Hispanic women in the U.S.-Mexico Border; Sioux/Native American women in the Northern Plains; white women in the Appalachia; and Vietnamese-American women in Pennsylvania and New Jersey. Our goal is to inform future research and outreach efforts to reduce the burden of cervical cancer in underserved populations. PMID:20310056

    Thorough study of advanced stages of lung cancer has been held. Delayed detection of most of the malignant tumours (IV stages) points to a number of problems existing in Georgia in terms of primary prevention and early detection of oncologic diseases. Hence, elaboration of strategy for prevention and early detection of oncologic diseases is of great importance for our country. Activities aimed at early detection of lung cancer under the conditions of low-level resources primarily imply education of population and professionals, as well as implementation of screening procedures. Cheap and effective methods should be applied for early diagnosis of one or two most widespread malignant tumours.

    Diet has an important role in the development of colorectal cancer. In the past few decades, findings from extensive epidemiologic and experimental investigations have linked consumption of several foods and nutrients to the risk of colorectal neoplasia. Calcium, fiber, milk, and whole grains have been associated with a lower risk of colorectal cancer, and red meat and processed meat have been associated with an increased risk. There is substantial evidence for the potential chemopreventive effects of vitamin D, folate, fruits, and vegetables. Nutrients and foods also may interact, as a dietary pattern, to influence colorectal cancer risk. Diet likely influences colorectal carcinogenesis through several interacting mechanisms. These include the direct effects on immune responsiveness and inflammation, and the indirect effects of overnutrition and obesity-risk factors for colorectal cancer. Emerging evidence also implicates the gut microbiota as an important effector in the relationship between diet and cancer. Dietary modification therefore has the promise of reducing colorectal cancer incidence.

    Breast cancer is one of the most common types of cancer in women, and is the second leading cause of cancer-related deaths in the United States. Chemoprevention using phytoestrogens (PEs) for breast cancer may be a valid strategy. PEs are phytochemicals with estrogen-like structures and can be classified into four types: isoflavones, lignans, stilbenes and coumestans. They are widely distributed in diet and herbs and have shown anti-cancer activity via mechanisms including estrogen receptor modulation, aromatase inhibition, and anti-angiogenesis. Genistein, daidzein and resveratrol are some of the most studied PE examples. Quality control in product manufacturing and clinical study design is a critical issue in developing them as clinically effective chemopreventive agents for breast cancer.

    Full Text Available The most recent estimates of the world-wide incidence of cancer indicate that gastric cancer was in 1990 the second most frequent cancer in the world (after lung cancer, with about 900 000 new cases diagnosed every year. Steady declines in the rates have been observed everywhere in the last few decades, but the absolute number of new cases per year is increasing mainly because of ageing of the population. The exact causes of the decline of gastric cancer are not well understood, but must include improvements in diet, food storage (e.g., refrigeration and, possibly, the decline of Helicobacter pylori infection. Dietary modifications and, possibly, vitamin supplements remain one of the most important tool for the prevention of gastric cancer. Control of H. pylori infection, by means of eradication or immunization, is also likely to offer great potential for the prevention of this important malignancy.

    The Stockholm Cancer Prevention Program (SCPP) is a community-based program aimed at reducing cancer incidence and mortality by reducing risk factors related to life-style: dietary habits, tobacco use, and sunbathing. The program, which came about as a result of a political initiative and commitment, has as its dietary objectives to reduce fat intake to 30% of energy and to increase fiber intake to 30 g/day. SCPP strives to achieve these goals by simultaneously affecting food supply and food demand. To date, the program collaborates with 12 municipalities and several large occupational health services and restaurant chains. It has developed cook books for caterers and the general public and has organized food fairs targeting policymakers and those working with food, education, or health promotion. SCPP emphasizes collaboration across sectors of society and has initiated contests for students studying food service technology and for retailers with the aim of promoting dietary change. The intervention is based on the principles and strategies of community organization.

    This feasibility study tested an instructional DVD program for improving cancer family caregivers' knowledge and preparedness in fall prevention and reducing fall occurrence among the patients they care for at home. DVD program features included training caregivers on safe mobility skills. Family caregivers of cancer patients were surveyed before and after viewing the DVD program on "Moving Safely" in the home. Cancer patients were followed 4 months postintervention to determine if fall occurrence was reduced. There was a decrease in the number of patients who fell postintervention compared with those who fell preintervention. Caregivers' perceptions of knowledge about fall prevention improved significantly after viewing the DVD. An instructional DVD program is an effective educational tool for preparing family caregivers with the knowledge and skills needed to reduce the incidence of falls in the home setting. Educators must develop programs for preparing family caregivers to perform nursing skills within the home.

    The implementation of European Commission directives has radically modified occupational risk management. In fact, widespread and continuous education addressed to exposed workers is seen by the legislator as one of the most effective means to avoid occupational diseases. The recent establishment of Continuing Medical Education (CME) has helped the system grant CME credits to participants in occupational courses organized by health-care providers. Moreover, the constant development of new health technologies coupled with the high productivity of the legislator confer a short lifetime on the acquired knowledge. Biological risks, biomechanical overload of the lumbar spine, and stress are among the classical risks requiring attention, discussion, and regular updating. Not only health-care workers but also safety technicians, occupational physicians, managers and union representatives should receive scheduled refresher training. Modern technologies such as distance learning, interactive simulation software, and online training tools are often the best teaching solutions. Occupational disease prevention should no longer be seen as a cost but as a cost savings indicator. Since it is closely related to quality promotion, it should play a primary role in the core business of health-care providers.

    Experimental studies have consistently shown the inhibitory activities of tea extracts on tumorigenesis in multiple model systems. Epidemiological studies, however, have produced inconclusive results in humans. A comprehensive review was conducted to assess the current knowledge on tea consumption and risk of cancers in humans. In general, consumption of black tea was not associated with lower risk of cancer. High intake of green tea was consistently associated with reduced risk of upper gastrointestinal tract cancers after sufficient control for confounders. Limited data support a protective effect of green tea on lung and hepatocellular carcinogenesis. Although observational studies do not support a beneficial role of tea intake on prostate cancer risk, phase II clinical trials have demonstrated an inhibitory effect of green tea extract against the progression of prostate pre-malignant lesions. Green tea may exert beneficial effects against mammary carcinogenesis in premenopausal women and recurrence of breast cancer. There is no sufficient evidence that supports a protective role of tea intake on the development of cancers of the colorectum, pancreas, urinary tract, glioma, lymphoma, and leukemia. Future prospective observational studies with biomarkers of exposure and phase III clinical trials are required to provide definitive evidence for the hypothesized beneficial effect of tea consumption on cancer formation in humans.

    Full Text Available Cervical cancer is a deadly cancer that clutches lives of the women in most of the cases due to lack of consciousness about the disease in the developing countries. It remains a threat which is second only to breast cancer in overall disease burden for women throughout the world. Cervical cancer is almost a preventable disease by prophylactic vaccine and routine screening. Both Cervarix and Gardasil vaccines have been effective in preventing persistent infection with targeted HPV types and in preventing cervical intraepithelial lesions. It is safe and nearly 100% effective if given before onset of sexual activity. This review article is aimed to explore different aspects of this vaccine as well as to develop awareness among health professionals of different disciplines.

  7. Targeting the Epigenome with Bioactive Food Components for Cancer Prevention

    Ong, Thomas Prates; Moreno, Fernando Salvador; Ross, Sharon Ann

    2012-01-01

    Epigenetic processes participate in cancer development and likely influence cancer prevention. Global DNA hypomethylation, gene promoter hypermethylation and aberrant histone post-translational modifications are hallmarks of neoplastic cells which have been associated with genomic instability and altered gene expression. Because epigenetic deregulation occurs early in carcinogenesis and is potentially reversible, intervention strategies targeting the epigenome have been proposed for cancer prevention. Bioactive food components (BFCs) with anticancer potential, including folate, polyphenols, selenium, retinoids, fatty acids, isothiocyanates and allyl compounds, influence DNA methylation and histone modification processes. Such activities have been shown to affect the expression of genes involved in cell proliferation, death and differentiation that are frequently altered in cancer. Although the epigenome represents a promising target for cancer prevention with BFCs, few studies have addressed the influence of dietary components on these mechanisms in vivo, particularly on the phenotype of humans, and thus the exact mechanisms whereby diet mediates an effect on cancer prevention remains unclear. Primary factors that should be elucidated include the effective doses and dose timing of BFCs to attain epigenetic effects. Because diet-epigenome interactions are likely to occur in utero, the impact of early-life nutrition on cancer risk programming should be further investigated. PMID:22353664

    2015-06-01

    The majority of adults worldwide own a mobile phone, including those in under-resourced communities. Mobile health (mhealth) education technologies present a promising mechanism for improving cancer prevention, treatment, and follow-up. The purpose of this study was to summarize the literature related to mobile phone (mhealth) applications for patient education specific to cancer and identify current recommendations from randomized studies. In particular, we were interested in identifying mobile phone applications along the cancer continuum, from cancer prevention to survivorship. The authors identified 28 articles reporting on mobile applications for patients related to cancer. Articles were identified in all categories along the cancer continuum, including health professional involvement in application development. Of these, six involved direct patient education, and eight focused on improving patient/professional communication and patient self-management. However, only six of the studies were randomized interventions. The potential for mobile applications to help overcome the "health care gap" has not yet been realized in the studies from the USA that were reviewed for this paper. However, early recommendations are emerging that support the use of mHealth communications to change behaviors for cancer prevention, early detection, and symptom management and improved patient-provider communication. Recommendations include short messages, use of multiple modalities as patient characteristics dictate comfort with mHealth communication, and the inclusion of patients and health professionals to develop and test applications. Tailoring mHealth to particular cultures, languages, and ethnic groups may also represent a unique possibility to provide accessible information and education at minimal cost for under-resourced communities and individuals.

  11. Psycho-oncology and primary prevention in cancer control plans: an absent voice?

    2015-07-27

    One third of cancer deaths are attributable to modifiable lifestyle, behaviour and psychosocial risk factors. Psycho-oncology can contribute significantly to prevention initiatives such as those described in national cancer control plans (NCCPs), to reduce or eliminate these risk factors. However, the extent to which psycho-oncology expertise has informed prevention objectives in plans is unclear. Accordingly, 35 English language NCCPs were located via existing databases and were searched using Adobe text searches ('psycho', 'social', 'behav' and 'intervention') to identify (a) representations of psycho-oncology, its dimensions (psychological, social and behavioural) and roles (e.g. psychologist); and (b) behaviour/lifestyle change interventions. A third of NCCPs included the term psycho- or psychosocial-oncology; approximately half referred to a psycho-oncology dimension regarding prevention and early detection and half included actions/objectives relating to health professionals and provision of psychosocial care. The majority of cancer plans included prevention outcomes and focussed primarily on smoking cessation and alcohol reduction. Interventions commonly proposed were education, regulation and service provision; however, many were aspirational statements of intent rather than specific interventions. Psycho-oncology was represented in NCCPs but was limited in reference to prevention with few behavioural interventions utilised. Psycho-oncology input is needed to prescribe evidence-based interventions in cancer plans that not only educate, regulate and provide resources but also motivate, empower and create a supportive normative environment for behaviour change. In this manuscript, and throughout this Special Issue on Cancer Prevention, important principles, ideas and evidence within psycho-oncology are outlined which, if properly implemented, can help reduce the global cancer burden.

    Knowledge gaps persist about the efficacy of cancer prevention strategies based on dietary food components. Adaptations to nutrient supply are executed through tuning of multiple protein networks that include transcription factors, histones, modifying enzymes, translation factors, membrane and nuclear receptors, and secreted proteins. However, the simultaneous quantitative and qualitative measurement of all proteins that regulate cancer processes is not practical using traditional protein methodologies. Proteomics offers an attractive opportunity to fill this knowledge gap and unravel the effects of dietary components on protein networks that impinge on cancer. The articles presented in this supplement are from talks proffered in the “Nutrition Proteomics and Cancer Prevention” session at the American Institute for Cancer Research Annual Research Conference on Food, Nutrition, Physical Activity and Cancer held in Washington, DC on October 21 and 22, 2010. Recent advances in MS technologies suggest that studies in nutrition and cancer prevention may benefit from the adoption of proteomic tools to elucidate the impact on biological processes that govern the transition from normal to malignant phenotype; to identify protein changes that determine both positive and negative responses to food components; to assess how protein networks mediate dose-, time-, and tissue-dependent responses to food components; and, finally, for predicting responders and nonresponders. However, both the limited accessibility to proteomic technologies and research funding appear to be hampering the routine adoption of proteomic tools in nutrition and cancer prevention research.

    Many studies have reported that adherence to health promotion guidelines for diet, physical activity, and maintenance of healthy body weight may decrease cancer incidence and mortality. A systematic review was performed to examine associations between adherence to established cancer prevention guidelines for diet and physical activity and overall cancer incidence and mortality. PubMed, Google Scholar, and Cochrane Reviews databases were searched following the current recommendations of Preferred Reporting Items for Systematic Reviews and Meta-analysis Approach (PRISMA). Twelve studies met inclusion criteria for this review. High versus low adherence to established nutrition and physical activity cancer prevention guidelines was consistently and significantly associated with decreases of 10% to 61% in overall cancer colorectal cancer incidence in both men and women (27%-52%). Consistent significant reductions were also shown for breast cancer incidence (19-60%), endometrial cancer incidence (23-60%), and colorectal cancer incidence in both men and women (35-52%). Findings for lung cancer incidence were equivocal and no significant relationships were found between adherence and ovarian or prostate cancers. Adhering to cancer prevention guidelines for diet and physical activity is consistently associated with lower risks of overall cancer incidence and mortality, including for some site-specific cancers.

    There is a scarcity of information about the proportion of the adult Saudi population that meet the recommended guidelines of physical activity (PA) to reduce cancer risk. Moreover, their awareness about the role of PA in cancer prevention is unclear. This cross-sectional study aimed at estimating the proportion of adult Saudis meeting the PA guidelines, specifically those recommended by American Cancer Society (ACS) for cancer prevention, and to assess the public awareness about the role of PA in cancer prevention. Using a multistage sampling method, 2,127 adult Saudis of both genders were recruited from 6 urban and 4 rural primary health care centers in Al Hassa, Saudi Arabia. Participants were personally interviewed to gather information about their sociodemographic characteristics, searching activity about PA and cancer, and the time spent in leisure time PA (moderate and vigorous)/week using the Global Physical Activity Questionnaire with show cards. Finally, items about the role of PA in cancer risk reduction were inquired. Of the included participants, 11.6% met the recommendations for cancer prevention (≥ 45 minutes of moderate-vigorous PA activity/≥ 5 days/week or 225 minutes/week). Multivariate regression showed that being male (AOR=1.49, CI=1.09-2.06), cancer prevention. Only 11.4% of the sample indicated correctly the frequency and duration of PA required for an average adult to be physically active and while >70% of them indicated the role of PA in prevention of hypertension, coronary heart disease and lowering elevated blood cholesterol, only 18.6% and 21.7% correctly mentioned the role of PA in reducing colon and breast cancer risk, respectively. Poor knowledge was found among those with less than college education and aged ≥ 50 years. The level of knowledge was significantly positively correlated with total leisure time PA of the participants. A minority of adult Saudis in Al Hassa was aware about the role of PA in cancer prevention and

    To guide skin cancer preventive interventions, this study examined correlates of sun safety behaviors in a racially and ethnically diverse sample of 407 adolescents completing a self-report survey at the time of their pediatric wellness visit. Adolescents regularly practiced few sun safety behaviors, and greater interest in cancer prevention was associated with more sun safety behaviors, ever smoking cigarettes was associated with fewer sun safety behaviors, and nonwhite minority adolescents practiced fewer sun safety behaviors than non-Hispanic whites. Clinical preventive interventions to increase sun safety practices among adolescents of all racial and ethnic backgrounds could be integrated into general cancer prevention education, including combining skin cancer prevention with antismoking counseling.

    2013-01-01

    Relationships between diet and health have attracted attention for centuries; but links between diet and cancer have been a focus only in recent decades. The consumption of diet-containing carcinogens, including polycyclic aromatic hydrocarbons and heterocyclic amines is most closely correlated with increasing cancer risk. Epidemiological evidence strongly suggests that consumption of dietary phytochemicals found in vegetables and fruit can decrease cancer incidence. Among the various vegetables, broccoli and other cruciferous species appear most closely associated with reduced cancer risk in organs such as the colorectum, lung, prostate and breast. The protecting effects against cancer risk have been attributed, at least partly, due to their comparatively high amounts of glucosinolates, which differentiate them from other vegetables. Glucosinolates, a class of sulphur- containing glycosides, present at substantial amounts in cruciferous vegetables, and their breakdown products such as the isothiocyanates, are believed to be responsible for their health benefits. However, the underlying mechanisms responsible for the chemopreventive effect of these compounds are likely to be manifold, possibly concerning very complex interactions, and thus difficult to fully understand. Therefore, this article provides a brief overview about the mechanism of such compounds involved in modulation of carcinogen metabolising enzyme systems.

    Improvement of cervical cancer statistics in Poland is believed to be one of the main goals of all medical services. Cervical cancer is an easily preventable neoplasm thus effective strategies for its prophylaxis should be proposed and introduced to the whole population of Polish citizens. The aim of the study was to measure the extent of knowledge of females about cervical cancer and its prevention. 250 female patients of gynecological clinic at the Medical Centre in Krakow, Poland, aged 18-60, were included into the retrospective study The research was based on an original questionnaire designed by the authors containing questions concerning general socio-epidemiological status, as well as cervical cancer epidemiology and HPV infection prevention methods. The majority of respondents (68%) rated their knowledge on cervical cancer prevention strategies as medium. The main sources of information on that prophylaxis were: women's magazines (59% of respondents), media (47%) and Internet (38%). Additionally only one in three women acquired that information from gynecologist The main reason for performing the Pap smear test was the request of the respondent (43% of cases). Only 3% of them attended the test as a result of a personal invitation sent by National Health Service. The main reasons for not attending Pap smear test were: fear of pain (39%), lack of any symptoms (18%), carelessness (15%) and embarrassment (12%). 1. Knowledge on HPV infections and cervical cancer prevention among women attending gynecological outpatient clinic is insufficient. 2. Education, especially in the field of cervical cancer main risk factors as well as the course of pap smear collection, seems to be necessary in order to reduce the cervical cancer morbidity and the fear of performing pap smear tests.

    Objective To understand the current level of knowledge about cancer prevention, the rutine of getting health information, as well as health education needs in rural residents, and the development of health education in rural areas. Methods A certain number of towns/sub-districts were randomly selected from 13 counties/districts in Henan, Anhui, Jiangsu and Shandong provinces. In each town/sub-district, residents from 21 to 70 years old were stratified into 5 age groups. Twenty subjects consisting of equal number of male and female were randomly selected from each group, totaling up to 100 subjects in each town/sub-district, and 23 000 in the study. A questionnaire survey on cancer risk factors, early symptoms, subjective needs, as well as the way of getting health information was conducted. Results The proportions of subjects who answered correctly the relationship between cancer and tobacco, alcohol, environment pollution, diet, occupational factors, infection, obesity as well as reproductive factors were respectively 87.4%, 73.0%,62. 0%, 45. 4%, 38. 3%, 36. 5%, 22. 2% and 13.5%. The proportions who correctly associated gradually enlarging mass or nodule, dysphagia, bleeding of undetermined origin, unexplained weight loss, long-term indigestion and hoarseness with cancer were respectively 72. 5%, 62. 0%, 60. 3%, 56. 7%, 45. 6% and 38. 8%. The old people and female had comparatively poor knowledge. The proportion of subjects who desired to get information about prevention, early symptom, diagnose, treatment and local prevalence were respectively 78. 2%, 63. 2%, 52. 5%, 37. 7% and 34. 1%. The three most popular sources of getting health information were television, broadcast and rural doctors, 81.0%, 57. 8% and 47.8% respectively. The old people preferred rural doctor and family/relative/friend to obtain health information, while young people preferred to television, intemet, hook/magazine/newspaper, as well as brochure

    Over the past few decades, the rate of cancer diagnosis has increased worldwide due to the increase in population and average life expectancy, and also, due to the advances in diagnostic medical technology that facilitate early cancer detection and recognition. Nonetheless, the treatment options have not been developed proportional to this increase, with a huge number of patients frequently being diagnosed with different types of fatal cancer. This has prompted different health organizations to search for novel strategies to prevent cancer, or even halt its progression. Having failed to provide optimum vascular protection benefits, especially with the introduction of relatively superior antiplatelets, such as adenosine diphosphate (ADP) receptor inhibitors; clopidogrel and ticagrelor, regular aspirin use was proposed to reduce the risk of common cancers like colorectal cancer, gastric cancer, breast cancer, lung cancer, prostate cancer and haematological malignancies, as suggested by epidemiological studies. However, it is difficult to draw any firm conclusions on such weak data, as this could raise false hopes among patients and physicians and could potentially mislead scientific research. Clearly, current evidence highlights a gap in medical research and emphasizes the need to carry out interventional studies in high risk for cancer patients using specific aspirin doses in order to validate the data. This should also shed some light on the risk-benefit profile in view of the potential for bleeding complications, especially with the higher doses.

    The recommendations of a major report on dietary aspects of cancer prevention are summarised and discussed. The findings of The World Cancer Research Fund (WCRF)/American Institute for Cancer Research (AICR) Second Expert Report Food, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective were published in 2007 and remain valid. The Report reviewed the relationship between food, nutrition, physical activity, body fatness and 17 cancer sites. The goal of the Report was to review all the relevant research, using precise and reproducible methodologies. An expert panel reviewed the evidence. Based upon evidence that was graded "convincing" or "probable", a series of 10 recommendations to reduce the risk of developing cancer was produced. One of the most important factors is maintaining a healthy weight throughout life, which can be achieved by regular physical activity and limiting consumption of energy-dense foods and sugary drinks. Other important dietary measures include consuming a diet high in plant-based foods, limiting intakes of red meat, and avoiding salty foods and processed meat. Alcohol should be consumed in modest amounts, if at all. Dietary supplements are not recommended for cancer prevention.

    Cervical cancer is the third most common cause of cancer in women in the world. During the past few decades tremendous strides have been made toward decreasing the incidence and mortality of cervical cancer with the implementation of various prevention and screening strategies. The causative agent linked to cervical cancer development and its precursors is the human papillomavirus (HPV). Prevention and screening measures for cervical cancer are paramount because the ability to identify and treat the illness at its premature stage often disrupts the process of neoplasia. Cervical carcinogenesis can be the result of infections from multiple high-risk HPV types that act synergistically. This imposes a level of complexity to identifying and vaccinating against the actual causative agent. Additionally, most HPV infections spontaneously clear. Therefore, screening strategies should optimally weigh the benefits and risks of screening to avoid the discovery and needless treatment of transient HPV infections. This article provides an update of the preventative and screening methods for cervical cancer, mainly HPV vaccination, screening with Pap smear cytology, and HPV testing. It also provides a discussion of the newest United States 2012 guidelines for cervical cancer screening, which changed the age to begin and end screening and lengthened the screening intervals.

    Colorectal cancer is one of the leading causes of morbidity and mortality worldwide. An early detection of colorectal cancer determines therapeutic outcomes, while primary prevention remains a challenge. Our aim was to review the dietary, geographical and genetic factors in the causation and their possible role in the primary prevention of colorectal cancer. Data from experimental and clinical studies and population screening programmes were analysed to determine the factors responsible for causation of colorectal cancer. The role of dietary constituents, including the consumption of fat, red meat, fibre content, alcohol consumption, and other lifestyle issues, including obesity, lack of exercise and geographical variations in cancer prevalence were reviewed. The role of genetic and lifestyle factors in causation of colorectal cancer is evident from the experimental, clinical and population-based studies. Dietary factors, including the consumption of fat, fibre, red meat and alcohol, seem to have a significant influence in this regard. The role of micronutrients, vitamins, calcium may be relevant but remain largely unclear. In conclusion, there is ample evidence favouring the role of various dietary and lifestyle factors in the aetiology of colorectal cancer. Modification of these factors is an attractive option, which is likely to help in the primary prevention and reduced disease burden.

    Full Text Available Without prevention or screening options available, ovarian cancer is the most lethal malignancy of the female reproductive tract. High grade serous ovarian cancer (HGSOC is the most common histologic subtype, and the role of germline BRCA1/2 mutation in predisposition and prognosis is established. Given the targeted treatment opportunities with PARP inhibitors, a predictive role for BRCA1/2 mutation has emerged. Despite recommendations to provide BRCA1/2 testing to all women with histologically confirmed HGSOC, uniform implementation remains challenging. The opportunity to review and revise genetic screening and testing practices will identify opportunities where universal adoption of BRCA1/2 mutation testing will impact and improve treatment of women with ovarian cancer. Improving education and awareness of genetic testing for women with cancer, as well as the broader general community, will help focus much needed attention on opportunities to advance prevention and screening programs in ovarian cancer. This is imperative not only for women with cancer, those at risk of developing cancer, but also for their first-degree relatives. In addition, BRCA1/2 testing may have direct implications for patients with other types of cancers, many which are now being found to have BRCA1/2 involvement.

    Breast cancer is the most common cancer among females worldwide. Several epidemiological studies suggested the inverse correlation between the intake of vegetables and fruits and the incidence of breast cancer. Substantial experimental studies indicated that many dietary natural products could affect the development and progression of breast cancer, such as soy, pomegranate, mangosteen, citrus fruits, apple, grape, mango, cruciferous vegetables, ginger, garlic, black cumin, edible macro-fungi, and cereals. Their anti-breast cancer effects involve various mechanisms of action, such as downregulating ER-α expression and activity, inhibiting proliferation, migration, metastasis and angiogenesis of breast tumor cells, inducing apoptosis and cell cycle arrest, and sensitizing breast tumor cells to radiotherapy and chemotherapy. This review summarizes the potential role of dietary natural products and their major bioactive components in prevention and treatment of breast cancer, and special attention was paid to the mechanisms of action.

    In this review of the scientific literature on the relationship between vegetable and fruit consumption and risk of cancer, results from 206 human epidemiologic studies and 22 animal studies are summarized. The evidence for a protective effect of greater vegetable and fruit consumption is consistent for cancers of the stomach, esophagus, lung, oral cavity and pharynx, endometrium, pancreas, and colon. The types of vegetables or fruit that most often appear to be protective against cancer are raw vegetables, followed by allium vegetables, carrots, green vegetables, cruciferous vegetables, and tomatoes. Substances present in vegetables and fruit that may help protect against cancer, and their mechanisms, are also briefly reviewed; these include dithiolthiones, isothiocyanates, indole-3-carbinol, allium compounds, isoflavones, protease inhibitors, saponins, phytosterols, inositol hexaphosphate, vitamin C, D-limonene, lutein, folic acid, beta carotene, lycopene, selenium, vitamin E, flavonoids, and dietary fiber. Current US vegetable and fruit intake, which averages about 3.4 servings per day, is discussed, as are possible noncancer-related effects of increased vegetable and fruit consumption, including benefits against cardiovascular disease, diabetes, stroke, obesity, diverticulosis, and cataracts. Suggestions for dietitians to use in counseling persons toward increasing vegetable and fruit intake are presented.

    Full Text Available Cancer is the second leading cause of death in the USA and an abundance of evidence suggests that lifestyle factors including smoking, the typical high-fat, refined-sugar diet and physical inactivity account for the majority of cancer. This review focuses on diet and inactivity as major factors for cancer promotion by inducing insulin resistance and hyperinsulinemia. Elevated levels of serum insulin impact on the liver primarily, increasing the production of insulin-like growth factor I (IGF-I while reducing the production of insulin-like growth factor binding protein 1 (IGFBP-1 resulting in stimulation of tumor cell growth and inhibition of apoptosis (programmed cell death. Adopting a diet low in fat and high in fiber-rich starch foods, which would also include an abundance of antioxidants, combined with regular aerobic exercise might control insulin resistance, reduce the resulting serum factors and thus reduce the risk for many different cancers commonly seen in the USA.

    Early case-control and intervention studies suggested that selenium (Se) species might reduce the risk of cancer and in a pre-diagnostic case-control study from 1986 [1] we found that the higher the serum Se concentration, the lower was the odds ratio of thyroid cancer. Our data showed, however, that this observation occurred late in the pre-diagnostic period indicating that low serum Se was simply a consequence of thyroid cancer. In 1986 we therefore concluded that the only way to get an indisputable and lasting answer to the question was to carry out properly designed intervention studies. Great was our frustration therefore when we in 2003 [2] discovered that thyroid cancer morbidity is a fractal variable powered by such complexity that we may never find a definite and enduring answer: Even the best, randomised, controlled trial comparing the incidence rate among exposed and controls can only produce temporary answers due to the complexity background. The only possible way to come up with a lasting solution seems to be by means of reductionist experiments, but they have to be tested on man and then one is back to square one.

    Full Text Available Background The incidence and mortality rates of breast cancer are high among Filipino women. The lack of knowledge on preventive behavior and early detection related to breast cancer is considered a reason. Objectives This study aimed to determine the association between knowledge about breast cancer and selected sociodemographic characteristics, daily life factors, reproductive factors, and perceived breast cancer risk factors. Patients and Methods This study used a cross-sectional design. The study population consisted of 527 women. Interviews were conducted by the investigators. The contents of the questionnaire collected basic characteristics of the respondents, including their sociodemographic profiles, their knowledge of breast cancer risk factors, preventive behaviors, early detection, and their daily life and reproductive factors. Predictor variables were analyzed using a Chi-square test, Fisher’s exact test, and a t-test. Multivariate logistic regression was applied for any significant differences (P < 0.005 among the predictor variables. One-way ANOVA and Tukey’s HDS were used to evaluate the association between education level and reproductive factors. Results Less than half of the women (42.7% had knowledge on breast cancer risk factors, and an equivalent number had knowledge on breast cancer symptoms. Women with higher educational levels were noted to give birth to their first child at a significantly older age and have a significantly lower number of childbirths. Multivariate logistic regression demonstrated that body mass index, education history, knowledge about symptoms, knowing how to conduct a breast self-examination, family history of cancer, and passive smoking could predict breast cancer knowledge. Conclusions Women who were aware of risk factors for breast cancer possessed a higher education level and had knowledge of the association of risk factors with preventive behaviors and early detection. However, a minority of

    Martínez, María Elena

    2005-01-01

    The past two decades have provided a vast amount of literature related to the primary prevention of colorectal cancer. Large international variation in colorectal cancer incidence and mortality rates and the prominent increases in the incidence of colorectal cancer in groups that migrated from low- to high-incidence areas provided important evidence that lifestyle factors influence the development of this malignancy. Moreover, there is convincing evidence from epidemiological and experimental studies that dietary intake is an important etiological factor in colorectal neoplasia. Although the precise mechanisms have not been clarified, several lifestyle factors are likely to have a major impact on colorectal cancer development. Physical inactivity and to a lesser extent, excess body weight, are consistent risk factors for colon cancer. Exposure to tobacco products early in life is associated with a higher risk of developing colorectal neoplasia. Diet and nutritional factors are also clearly important. Diets high in red and processed meat increase risk. Excess alcohol consumption, probably in combination with a diet low in some micronutrients such as folate and methionine, appear to increase risk. There is also recent evidence supporting a protective effect of calcium and vitamin D in the etiology of colorectal neoplasia. The relationship between intake of dietary fiber and risk of colon cancer has been studied for three decades but the results are still inconclusive. However, some micronutrients or phytochemicals in fiber-rich foods may be important; folic acid is one such micronutrient that has been shown to protect against the development of colorectal neoplasia and is currently being studied in intervention trials of adenoma recurrence. The overwhelming evidence indicates that primary prevention of colon cancer is feasible. Continued focus on primary prevention of colorectal cancer, in combination with efforts aimed at screening and surveillance, will be vital in

    Innovative marketing campaigns and promotional activities can successfully contribute to the improvement of public health by raising the level of general knowledge about health issues and benefits that the change of habits, eradication of undesirable behaviour and regular medical controls have. The focus should be on continuous marketing communication through various mass media or direct communication between medical staff and patients. The aim of this paper was to define the role that various communication channels have in the process of informing and educating the target group in case of breast and cervical cancer prevention. The survey based on polling a sample of 2,100 female patients of the Serbian Railways Medical Centre was conducted in the period October- December 2013. The questionnaire included questions about demographic characteristics, prevention habits of women, their level of information on that topic and communication channels they prefer. There is a difference among respondents' awareness level about preventive measures depending on demographic and geographical criteria. The results indicate the existence of variations in frequency of performing gynaecological examinations and Pap tests depending on different age, educational and residential groups. Although the largest percentage of women stated familiarity with the way of performing breast self-examination (78%), the majority of them had never performed mammography or ultrasonography (67%). The greatest number of women were informed about the possibility of preventing breast and cervical cancer by posters or brochures in health institutions (71%) and mass media--television on the first place (74%), then specialized magazines about health (48%), radio (48%), web sites about health (42%), and daily newspapers (34%). The respondents consider the Ministry of Health and health institutions as the most responsible subjects for education of women about cancer prevention, while the self-initiative was

    2014-10-01

    Full Text Available Isoflavones (IF such as genistein are cancer preventive phytochemicals found in soy and other legumes. Epidemiological studies point to a reduced risk for hormone‑dependent cancers in populations following a typical Asian diet rich in soy products. IF act as phytoestrogens and prevent tumorigenesis in rodent models by a broad spectrum of bioactivities. During the past 10 years, IF were shown to target all major epigenetic mechanisms regulating gene expression, including DNA methylation, histone modifications controlling chromatin accessibility, and non-coding RNAs. These effects have been suggested to contribute to cancer preventive potential in in vitro and in vivo studies, affecting several key processes such as DNA repair, cell signaling cascades including Wnt-signaling, induction of apoptosis, cell cycle progression, cell proliferation, migration and invasion, epithelial-mesenchymal transition (EMT, metastasis formation and development of drug-resistance. We here summarize the state-of-the-art of IF affecting the epigenome in major hormone-dependent, urogenital, and gastrointestinal tumor types and in in vivo studies on anti-cancer treatment or developmental aspects, and short-term intervention studies in adults. These data, while often requiring replication, suggest that epigenetic gene regulation represents an important novel target of IF and should be taken into consideration when evaluating the cancer preventive potential of IF in humans.

    In men, prostate cancer is the most common non-cutaneous malignancy and the second most common cause of cancer death. Skeletal complications occur at various points during the disease course, either due to bone metastases directly, or as an unintended consequence of androgen deprivation therapy (ADT). Bone metastases are associated with pathologic fractures, spinal cord compression, and bone pain and can require narcotics or palliative radiation for pain relief. ADT results in bone loss and fragility fractures. This review describes the biology of bone metastases, skeletal morbidity, and recent advances in bone-targeted therapies to prevent skeletal complications of prostate cancer.

  1. Role of antioxidants in the prevention of cancer

    Directory of Open Access Journals (Sweden)

    Laura Llacuna

    2014-05-01

    Full Text Available The nature of the association between free radicals and cancer is complex and paradoxical, as it seems that free radicals and oxidative stress can induce cancer, but at the same time the transformed cells, that is, the cancer cells generate more free radicals than normal cells. Endogenous antioxidant compounds, including glutathione and lysozyme, can limit the effects of oxidative stress, but these systems can be quickly saturated by high amounts of free radicals. It is important to increase the cellular levels of antioxidants that could provide protection against possible adverse agents that can cause a cell cancer. A good diet and the knowledge of several compounds of foods with antioxidant effects may be helpful to prevent cancer disease.

  2. Fasting and Caloric Restriction in Cancer Prevention and Treatment.

    Science.gov (United States)

    Brandhorst, Sebastian; Longo, Valter D

    Cancer is the second leading cause of death in the USA and among the leading major diseases in the world. It is anticipated to continue to increase because of the growth of the aging population and prevalence of risk factors such as obesity, smoking, and/or poor dietary habits. Cancer treatment has remained relatively similar during the past 30 years with chemotherapy and/or radiotherapy in combination with surgery remaining the standard therapies although novel therapies are slowly replacing or complementing the standard ones. According to the American Cancer Society, the dietary recommendation for cancer patients receiving chemotherapy is to increase calorie and protein intake. In addition, there are no clear guidelines on the type of nutrition that could have a major impact on cancer incidence. Yet, various forms of reduced caloric intake such as calorie restriction (CR) or fasting demonstrate a wide range of beneficial effects able to help prevent malignancies and increase the efficacy of cancer therapies. Whereas chronic CR provides both beneficial and detrimental effects as well as major compliance challenges, periodic fasting (PF), fasting-mimicking diets (FMDs), and dietary restriction (DR) without a reduction in calories are emerging as interventions with the potential to be widely used to prevent and treat cancer. Here, we review preclinical and preliminary clinical studies on dietary restriction and fasting and their role in inducing cellular protection and chemotherapy resistance.

    2011-01-01

    Strong evidence now supports the adoption of cervical cancer prevention strategies that explicitly focus on persistent infection with the causal agent, human papillomavirus (HPV). To inform an evidence-based transition to a new public health approach for cervical cancer screening, we summarize the natural history and cervical carcinogenicity of HPV and discuss the promise and uncertainties of currently available screening methods. New HPV infections acquired at any age are virtually always benign, but persistent infections with one of approximately 12 carcinogenic HPV types explain virtually all cases of cervical cancer. In the absence of an overtly persistent HPV infection, the risk of cervical cancer is extremely low. Thus, HPV test results predict the risk of cervical cancer and its precursors (cervical intraepithelial neoplasia grade 3) better and longer than cytological or colposcopic abnormalities, which are signs of HPV infection. The logical and inevitable move to HPV-based cervical cancer prevention strategies will require longer screening intervals that will disrupt current gynecologic and cytology laboratory practices built on frequent screening. A major challenge will be implementing programs that do not overtreat HPV-positive women who do not have obvious long-term persistence of HPV or treatable lesions at the time of initial evaluation. The greatest potential for reduction in cervical cancer rates from HPV screening is in low-resource regions that can implement infrequent rounds of low-cost HPV testing and treatment. PMID:21282563

    Full Text Available Cancer is a worldwide problem that is caused by a variety of different factors increasing over a number of years. Oral cancer is a very prevalent disease and one of the most 10 common causes of death. It is important that the risk factors can be controlled. Selecting the correct health behaviors and preventing exposure to convinced environmental risk factors can help to prevent the expansion of cancer. Scientists guess that as many as 30-40 percent of all cancer-related deaths are caused by human behaviors such as smoking, consumption of alcohol, poor diet quality and physical inactivity. This result explains the tendency in the following behaviors that can influence the possibility of getting cancer, especially oral cancer in addition to providing information and classes about healthy eating habits and a subsequent healthy lifestyle at home. In fact, a diet rich in fresh fruits, whole grains and vegetables can decrease the risk of the oral cancer because of certain compounds such as vitamin C, E, carotenoids and lycopene. Moreover, limit consumption of meat, particularly processed meat, and replace it with vegetable proteins and fish (rich of omega 3 are helpful and effective.

  5. Dietary Polyphenols in Prevention and Treatment of Prostate Cancer

    2015-02-01

    Full Text Available Prostate cancer is the most prevalent disease affecting males in many Western countries, with an estimated 29,480 deaths in 2014 in the US alone. Incidence rates for prostate cancer deaths have been decreasing since the early 1990s in men of all races/ethnicities, though they remain about 60% higher in African Americans than in any other group. The relationship between dietary polyphenols and the prevention of prostate cancer has been examined previously. Although results are sometimes inconsistent and variable, there is a general agreement that polyphenols hold great promise for the future management of prostate cancer. Various dietary components, including polyphenols, have been shown to possess anti-cancer properties. Generally considered as non-toxic, dietary polyphenols act as key modulators of signaling pathways and are therefore considered ideal chemopreventive agents. Besides possessing various anti-tumor properties, dietary polyphenols also contribute to epigenetic changes associated with the fate of cancer cells and have emerged as potential drugs for therapeutic intervention. Polyphenols have also been shown to affect post-translational modifications and microRNA expressions. This article provides a systematic review of the health benefits of selected dietary polyphenols in prostate cancer, especially focusing on the subclasses of polyphenols, which have a great effect on disease prevention and treatment.

    2013-12-01

    In contrast to the consistent results of an inhibitory effect of green tea extracts and tea polyphenols on the development and growth of carcinogen-induced tumors in experimental animal models, results from human studies are mixed. Both observational and intervention studies have provided evidence in support of a protective role of green tea intake in the development of oral-digestive tract cancer or an inhibitory role of oral supplementation of green tea extract on a precancerous lesion of oral cavity. Evidence in support of green tea intake against the development of liver cancer risk is limited and inconsistent. An inverse association between green tea intake and lung cancer risk has been observed among never smokers but not among smokers. Although observational studies do not support a beneficial role of tea intake against the development of prostate cancer, several phase 2 clinical trials have shown an inhibitory effect of green tea extract against the progression of prostate premalignant lesions to malignant tumors. Prospective epidemiologic studies so far have not provided evidence for a protective effect of green tea consumption on breast cancer development. Current data neither confirm nor refute a definitive cancer-preventive role of green tea intake. Large randomized intervention trials on the efficacy of green tea polyphenols or extracts are required before a recommendation for green tea consumption for cancer prevention should be made.

Information gathered from 727 persons (341 males and 386 females) showed that most of the subjects consider cancer as the most alarming disease and pain as its most distressing problem. More than half of them think that cancer is curable in only 25% cases and 72% think it is 'sometimes' preventable. The commonest site of cancer, according to 38% of them, is stomach whereas that in female, according to 52% is uterus. Most of them are well aware about the risk of repeated x-ray exposures, smoke and dust but not about oral contraceptives. Majority (92%) opined in favour of a cancer specialist for consultation and more than 98% think that cancer, once diagnosed, must be treated, preferably with radiotherapy (45%), against surgery (29%) and anti-cancer chemotherapy (24%). Early detection was emphasised by 78% for increasing cure rate. Shyness was thought by the majority to be the chief cause of delay in seeking treatment in case of breast cancer cases. As health education media television and cinema slides were considered to be most effective. Most of the subjects advocated for psychological (47%) or medical (34%) support in the terminal stages of cancer.

    Full Text Available Pooja Advani, Alvaro Moreno-AspitiaDepartment of Hematology and Oncology, Mayo Clinic, Jacksonville, FL, USAAbstract: Due to the high incidence of breast cancer in the United States, optimal strategies for its prevention are imperative. This entails identification of women who are at an increased risk for breast cancer and an integrative approach that includes effective screening methods as well as nutritional, pharmacologic, and surgical management. Several breast cancer risk-assessment tools, such as the Gail and Claus models, can help clinicians determine the quantitative risk of breast cancer. The role of selective estrogen receptor modulators, such as tamoxifen and raloxifene, for the prevention of breast cancer has been well established. Several other agents, such as aromatase inhibitors, are currently being investigated. The potential adverse effects of these chemopreventive agents, which include an impact on the quality of life, must be discussed with the patient before deciding on this approach. Additionally, breast cancer risk factors have been identified over the years; some of them are modifiable, but others are not. Although there is no conclusive evidence to suggest the protective role of specific dietary components, alcohol consumption and obesity are associated with an increased breast cancer risk; thus lifestyle changes can lead to a lower risk of developing breast cancer. Surgical approaches, including bilateral risk-reduction mastectomy and salpingo-oophorectomy, are usually limited to women with a hereditary predisposition to development of breast cancer. The objective of this review is to summarize the various approaches directed at reducing the incidence of breast cancer.Keywords: chemoprevention, tamoxifen, raloxifene, prophylactic surgery

    The main purpose of this study was to evaluate the effectiveness of the education system using social media. Eight educational video clips were developed instructing the viewer on cancer-related issues such as prevention, treatment, and survivorship. Each video was made with participation of medical professors and posted on a YouTube channel. A mobile phone application was produced containing a scheduler function, introduction of a community cancer center program, and cancer information. A medical blog was established to provide stationary materials such as images and articles. Descriptive analysis was done by Google analytics. From May of 2014 to June of 2016, 15,247 total views were recorded on the YouTube channel, and the average view duration was about 3 min. The most popular video was about chemotherapy treatment; 5409 (36%) people watched this video, and 3615 (23.5%) people viewed a video on balanced dietary habits. As well as South Korea, 1,113 (7%) views were confirmed in the United States and 175 (1%) in Japan. The equipment used to watch the contents were mobile phones (59%), laptops (33%), and tablets (6%). Five hundred people installed the smartphone application from March of 2015 to July of 2016. Three hundred eighty-three medical contents were posted on the blog since March of 2015. Cancer education is necessary to address the education needs of patients with cancer and their caregivers. Education based on social media could be an effective method that reaches beyond geographical boundaries.

    2008-04-01

    Digoxin-like immunoreactive factor (DLIF) and ouabain-like factor (OLF) are the mammalian counterparts to the plant-derived cardiotonic steroids digoxin and ouabain. Compelling evidence indicates that the cardiotonic steroids may have anticancer properties. Recent evidence indicates that low (nanomolar) concentrations of DLIF selectively induce cell death in transformed cells, while sparing normal cells, and is even more potent than the plant-derived compounds. The discovery that these endogenous molecules may play a role in the regulation of cancer cell proliferation provides a potentially new paradigm for the physiologic role of DLIF and OLF. In addition, the possible use of digoxin itself as a therapeutic agent in cancer has been explored, and evidence suggests that its conversion to dihydrodigoxin may be involved in regulating anticancer activity. The mechanism(s) for the pro-apoptotic property of these compounds is not known. In this brief review, we will discuss the proposed mechanism of action of digoxin, ouabain, DLIF, and OLF as anticancer compounds and discuss the effects that metabolic conversion to their dihydro-derivatives may have on this activity. From the perspective of therapeutic drug monitoring, these findings suggest some potential new challenges in the need to measure concentrations of digoxin and dihydrodigoxin as well as their endogenous counterparts DLIF and OLF in serum.

    Full Text Available Introduction. HPV infection is the most frequent sexually transmitted disease and a major epidemiological problem in the world. HPV 16 and HPV 18 are responsible for over 70.0% cases of cervical cancer. The aim of this study was to evaluate the knowledge of young women concerning HPV infection as well as possibilities of cervical cancer prevention. Moreover, the study had to determine which groups of young women especially required educational campaigns. Material and methods. The questionnaire survey was carried out among 126 young Polish women aged 18–35. The results were statistically analyzed. Results. The survey found that 41.3% women had heard about HPV before interview. Nearly 38.5% of women correctly indicated the occurrence of cancer which is associated with HPV infection. About 23.0% of women received a vaccination against HPV, only 19.2% of women correctly identified who should be subjected to vaccination. The best knowledge about cervical cancer and disease prevention was manifested among female university graduates and groups living in urban areas. Those women also more often underwent cytological screening. Conclusions. Educational campaigns should particularly include group of women living in the rural areas and women with primary and secondary education.

    Full Text Available In breast cancer patients, bone is the most common site of metastases. Medical therapies are the basic therapy to prevent distant metastases and recurrence and to cure them. Radiotherapy has a primary role in pain relief, recalcification and stabilization of the bone, as well as the reduction of the risk of complications (e.g., bone fractures, spinal cord compression. Bisphosphonates, as potent inhibitors of osteoclastic-mediated bone resorption are a well-established, standard-of-care treatment option to reduce the frequency, severity and time of onset of the skeletal related events in breast cancer patients with bone metastases. Moreover bisphosphonates prevent cancer treatment-induced bone loss. Recent data shows the anti-tumor activity of bisphosphonates, in particular, in postmenopausal women and in older premenopausal women with hormone-sensitive disease treated with ovarian suppression. Pain is the most frequent symptom reported in patients with bone metastases, and its prevention and treatment must be considered at any stage of the disease. The prevention and treatment of bone metastases in breast cancer must consider an integrated multidisciplinary approach.

    Women with evidence of high intake ratios of the marine omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) relative to the omega-6 arachidonic acid have been found to have a reduced risk of breast cancer compared with those with low ratios in some but not all case-control and cohort studies. If increasing EPA and DHA relative to arachidonic acid is effective in reducing breast cancer risk, likely mechanisms include reduction in proinflammatory lipid derivatives, inhibition of nuclear factor-κB-induced cytokine production, and decreased growth factor receptor signaling as a result of alteration in membrane lipid rafts. Primary prevention trials with either risk biomarkers or cancer incidence as endpoints are underway but final results of these trials are currently unavailable. EPA and DHA supplementation is also being explored in an effort to help prevent or alleviate common problems after a breast cancer diagnosis, including cardiac and cognitive dysfunction and chemotherapy-induced peripheral neuropathy. The insulin-sensitizing and anabolic properties of EPA and DHA also suggest supplementation studies to determine whether these omega-3 fatty acids might reduce chemotherapy-associated loss of muscle mass and weight gain. We will briefly review relevant omega-3 fatty acid metabolism, and early investigations in breast cancer prevention and survivorship.

    Purpose Nearly 1 in 4 breast cancers is diagnosed before the age of 50, and many early-stage premalignant lesions are present but not yet diagnosed. Therefore, we review evidence to support the strategy that breast cancer prevention efforts must begin early in life. Methods Literature review Results Exposures during childhood and adolescence affect a woman’s long-term risk of breast cancer, but have received far less research attention than exposures that occur later in life. Breast tissue undergoes rapid cellular proliferation between menarche and first full-term pregnancy, and risk accumulates rapidly until the terminal differentiation that accompanies first pregnancy. Evidence on childhood diet and growth in height, and adolescent alcohol intake, among other adolescent factors are related to breast cancer risk and risk of premalignant proliferative benign lesions. Conclusion Breast cancer prevention efforts will have the greatest effect when initiated at an early age and continued over a lifetime. Gaps in knowledge are identified and deserve increase attention to inform prevention. PMID:24820413

    The main diet-related cancers include colorectal, lung, breast in (postmenopausal) women, stomach, esophagus, prostate and pancreas. After tobacco, obesity is the leading cause of cancer; it accounts for one third of all cancers. Cancer is associated with high total body fat, abdominal fat and weight gain in adult life. These are all potentially modifiable risk factors. Consumption of a "healthy diet" and living an "active life" can significantly reduce the risk of cancer. The aim of this study was to analyze the recommendations published by the World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) for the prevention of cancer in 2007. We compared the recommendations of Food, Nutrition and Physical Activity and the Prevention of Cancer: a global perspective", with the national situation in Chile, analyzing the national report on the prevalence of risk factors. Our main finding was that the pattern of consumption and lifestyles differ markedly from the WCRF recommendations: we observed an over consumption of sugary drinks and high intake of processed foods high in sodium and total fat and low consumption of legumes, vegetables, fruits high in antioxidants and fiber that protect from cancer. Chile has an increased cancer prevalence which is associated with poor quality diets, rising mean body mass index and a sedentary behavior. We recommend the strengthening programs to promote healthy diets and active living, in order to reduce cancer risk.

    Functional food for prevention of chronic diseases is one of this century's key global challenges. Cancer is not only the first or second leading cause of death in China and other countries across the world, but also has diet as one of the most important modifiable risk factors. Major dietary factors now known to promote cancer development are polished grain foods and low intake of fresh vegetables, with general importance for an unhealthy lifestyle and obesity. The strategies of cancer prevention in human being are increased consumption of functional foods like whole grains (brown rice, barley, and buckwheat) and by-products, as well some vegetables (bitter melon, garlic, onions, broccoli, and cabbage) and mushrooms (boletes and Tricholoma matsutake). In addition some beverages (green tea and coffee) may be protective. Southwest China (especially Yunnan Province) is a geographical area where functional crop production is closely related to the origins of human evolution with implications for anticancer influence.

    This presentation focuses on research that could theoretically be applied to implement the strategy of general population chemoprevention. The concept is based on the premise of enhancing foods with known anticarcinogens through either agricultural methods or food-processing technologies. Two areas of our work are described: (a) garlic cultivated with selenium fertilization and (b) foods high in conjugated linoleic acid. Both selenium and conjugated linoleic acid are powerful chemopreventive agents in the animal tumor model. The rationale of delivering these two specific compounds through the food system will be developed. Preliminary studies will be summarized to show the feasibility of this approach in suppressing carcinogen-induced mammary cancer in rats. Finally, the advantages of using foods to provide anticarcinogens to the general population as part of a chemopreventive strategy will also be discussed.

    2008-01-01

    There are significant challenges to communicating relevant cancer prevention and control information to health care consumers due both to the complexities of the health information to be communicated and the complexities of health communication, especially with vulnerable populations. The need for effective communication about cancer risks, early detection, prevention, care, and survivorship is particularly acute, yet also tremendously complex, for reaching vulnerable populations, those groups of people who are most likely to suffer significantly higher levels of morbidity and mortality from cancers than other segments of the population. These vulnerable populations, typically the poorest, lowest educated, and most disenfranchised members of modern society, are heir to serious cancer-related health disparities. Vulnerable populations often have health literacy difficulties, cultural barriers, and economic challenges to accessing and making sense of relevant health information. This paper examines these challenges to communicating relevant information to vulnerable populations and suggests strategies for effectively using different communication media for marketing cancer prevention and control to reduce health disparities and promote public health.

  9. Eradication of H pylori for the prevention of gastric cancer

    2006-01-01

    Tnfection with H pylori is the most important known etiological factor associated with gastric cancer. While colonization of the gastric mucosa with H pylori results in active and chronic gastritis in virtually all individuals infected, the likelihood of developing gastric cancer depends on environmental, bacterial virulence and host specific factors. The majority of all gastric cancer cases are attributable to H pylori infection and therefore theoretically preventable. There is evidence from animal models that eradication of H pylori at an early time point can prevent gastric cancer development. However, randomized clinical trials exploring the prophylactic effect of H pylori eradication on the incidence of gastric cancer in humans remain sparse and have yielded conflicting results. Better markers for the identification of patientsat risk for H pylori induced gastric malignancy are needed to allow the development of a more efficient public eradication strategy. Meanwhile, screening and treatment of H pylori in first-degree relatives of gastric cancer patients as well as certain high-risk populations might be beneficial.

    Full Text Available Background Cervical cancer is the fourth most common cancer among women worldwide. Organized cervical screening and vaccination against human papilloma virus (HPV have been successful interventions for prevention of invasive cervical cancer (ICC. Because of cultural and religious considerations, ICC has low incidence in Iran and many other Muslim countries. There is no organized cervical screening in these countries. Therefore, ICC is usually diagnosed in advanced stages with poor prognosis in these countries. We performed a priority setting exercise and suggested priorities for prevention of ICC in this setting. Methods We invited experts and researchers to a workshop and asked them to list important suggestions for ICC prevention in Iran. After merging similar items and removing the duplicates, we asked the experts to rank the list of suggested items. We used a strategy grid and Go-zone analysis to determine final list of priorities for ICC prevention in Iran. Results From 26 final items suggested as priorities for prevention of ICC, the most important priorities were developing national guidelines for cervical screening and quality control protocol for patient follow-up and management of precancerous lesions. In addition, we emphasized considering insurance coverage for cervical screening, public awareness, and research priorities, and establishment of a cervical screening registry. Conclusion A comprehensive approach and implementation of organized cervical screening program is necessary for prevention of ICC in Iran and other low incidence Muslim countries. Because of high cost for vaccination and low incidence of cervical cancer, we do not recommend HPV vaccination for the time being in Iran.

  13. Identifying molecular targets of lifestyle modifications in colon cancer prevention

    Full Text Available One in four deaths in the United States is cancer-related, and colorectal cancer (CRC is the second leading cause of cancer-associated deaths. Screening strategies are utilized but have not reduced disease incidence or mortality. In this regard, there is an interest in cancer preventive strategies focusing on lifestyle intervention, where specific etiologic factors involved in cancer initiation, promotion, and progression could be targeted. For example, exposure to dietary carcinogens, such as nitrosamines and polycyclic aromatic hydrocarbons influences colon carcinogenesis. Furthermore, dietary deficiencies could alter sensitivity to genetic damage and influence carcinogen metabolism contributing to CRC. High alcohol consumption increases the risk of mutations including the fact that acetaldehyde, an ethanol metabolite, is classified as a group 1 carcinogen. Tobacco smoke exposure is also a risk factor for cancer development; ~20% of CRCs are associated with smoking. Additionally, obese patients have a higher risk of cancer development, which is further supported by the fact that physical activity decreases CRC risk by 55%. Similarly, chronic inflammatory conditions also increase the risk of CRC development. Moreover, the circadian clock alters digestion and regulates other biochemical, physiological and behavioral processes that could positively influence CRC. Taken together, colon carcinogenesis involves a number of etiological factors, and therefore, to create effective preventive strategies, molecular targets need to be identified and beleaguered prior to disease progression. With this in mind, the following is a comprehensive review identifying downstream target proteins of the above lifestyle risk factors, which are modulated during colon carcinogenesis and could be targeted for CRC prevention by novel agents including phytochemicals.

    Alcohol consumption is associated with a higher risk of colorectal cancer, but to the authors' knowledge its influence on survival after a diagnosis of colorectal cancer is unclear. The authors investigated associations between prediagnosis and postdiagnosis alcohol intake with mortality among survivors of colorectal cancer. The authors identified 2458 men and women who were diagnosed with invasive, nonmetastatic colorectal cancer between 1992 (enrollment into the Cancer Prevention Study II Nutrition Cohort) and 2011. Alcohol consumption was self-reported at baseline and updated in 1997, 1999, 2003, and 2007. Postdiagnosis alcohol data were available for 1599 participants. Of the 2458 participants diagnosed with colorectal cancer, 1156 died during follow-up through 2012. Prediagnosis and postdiagnosis alcohol consumption were not found to be associated with all-cause mortality, except for an association between prediagnosis consumption of Alcohol use was generally not associated with colorectal cancer-specific mortality, although there was some suggestion of increased colorectal cancer-specific mortality with postdiagnosis drinking (RR, 1.27 [95% CI, 0.87-1.86] for current drinking of alcohol consumption and all-cause mortality among individuals with nonmetastatic colorectal cancer. The association between postdiagnosis drinking and colorectal cancer-specific mortality should be examined in larger studies of individuals diagnosed with nonmetastatic colorectal cancer.

    This study was designed to segment the audience group of '10 lifestyle for cancer prevention' based on demographic characteristics and the level of knowledge about each guideline for cancer prevention among the community in South Korea. Participants were chosen through stratified random sampling according to the age and gender distribution of Gangwon province in South Korea. A telephone survey was conducted from 6 to 15 calls among 2,025 persons on October 2008. A total of 1,687 persons completed the survey (response rate: 83.3%). Survey items were composed of socio-demographic characteristics such as age, gender, income, education, and residence area and the knowledge level of '10 guidelines for cancer prevention', developed by 'Korean Ministry of Health and Welfare' and covering smoking cessation, appropriate drinking, condom use, and regular physical activity and so on. We selected the priority needed to promote awareness and segmented the audience group based on the demographic characteristics, homogeneous with respect to the knowledge level using Answer Tree 3.0 with CHAID as a data mining algorithm. The results of analysis showed that each guideline of ' 10 lifestyle for cancer prevention' had its own segmented subgroup characterized by each demographic. Especially, residence area, city or county, and ages were the first split on the perceived level of knowledge and these findings suggested that segmentation of audiences for targeting is needed to deliver more effective education of patients and community people. In developing the strategy for effective education, the method of social marketing using the decision tree analysis could be a useful and appropriate tool. The study findings demonstrate the potential value of using more sophisticated strategies of designing and providing health information based on audience segmentation.

    Delayed diagnosis is a major contributing factor to the UK's lower cancer survival compared to many European countries. In the UK, there is a significant national variation in early cancer diagnosis. Healthcare providers can offer an insight into local priorities for timely cancer diagnosis. In this study, we aimed to identify the main problems and solutions relating to delay cancer diagnosis according to cancer care clinicians. We developed and implemented a new priority-setting approach called PRIORITIZE and invited North West London cancer care clinicians to identify and prioritize main causes for and solutions to delayed diagnosis of cancer care. Clinicians identified a number of concrete problems and solutions relating to delayed diagnosis of cancer. Raising public awareness, patient education as well as better access to specialist care and diagnostic testing were seen as the highest priorities. The identified suggestions focused mostly on the delays during referrals from primary to secondary care. Many identified priorities were feasible, affordable and converged around common themes such as public awareness, care continuity and length of consultation. As a timely, proactive and scalable priority-setting approach, PRIORITZE could be implemented as a routine preventative system for determining patient safety issues by frontline staff.

    Essentially, people's diet and nutritional status has been changed substantially worldwide and several lines of evidence suggest that these changes are to the detriment of their health. Additionally, it has been well documented that unhealthy diet especially the fast foods, untraditional foods or bad-eating-habits influence the human gut microbiome. The gut microbiota shapes immune responses during human life and affects his/her metabolomic profiles. Furthermore, many studies highlight the molecular pathways that mediate host and symbiont interactions that regulate proper immune function and prevention of cancer in the body. Intriguingly, if cancer forms in a human body due to the weakness of immune system in detriment of microbiome, the removal of cancer stem cells can be carried out through early Calories Restriction with Annual Fasting (AF) before tumor development or progress. Besides, fasting can balance the gut microbiome for enhancement of immune system against cancer formation.

    Consuming a diet that is rich in fruits and vegetables is critical for preventing cancer and cancer-related disparities. Food systems approaches that increase spatial-temporal, economic, and social access to fruits and vegetables may ultimately result in improved consumption patterns among Americans. Engaging the triad of Cooperative Extension Services, public health systems, and community health centers may yield maximal public health benefits from food systems interventions. These entities have a mutual interest in promoting health equity and community and economic vitality that provides common ground to (a) implement solutions through the dissemination of evidence-based programs and (b) share resources to foster grassroots support for sustained change. Working together, these systems have an unprecedented opportunity to build on their common ground to implement, evaluate, and disseminate evidence-based food systems interventions in communities and with populations experiencing disparate risk for cancer and cancer-related diseases.

    Full Text Available Oral cancer is one of the usual causes of mortality all over the world, with a five-year survival rate of only 50%. Oral cancers are treated primarily by surgery with / without adjuvant radiotherapy and / or chemotherapy. However, there is significant post-treatment morbidity and mortality secondary to recurrences. Dietary supplements like fruits and vegetables are rich in phytochemicals and provide a variety of antioxidants like vitamin A, C, E. Spirulina, Selenium, Green tea (EGCG, Neem, Tomatoes (lycopene, Turmeric (curcumin, and some medicinal mushrooms are also used as chemopreventive and chemotherapeutic agents. This overview emphasizes on natural therapies to fight against oral cancer. Thus, there are several natural compounds that can enhance the prevention of oral cancer.

    Colorectal adenocarcinoma is a major cause of cancer-related morbidity and mortality in Belgium and in other western countries. Prevention implies a modification of alimentation and maybe a chronic uptake of acetylsalicylic acid. Treatment of colorectal cancers is based on surgery and the prognosis is determined by the locoregional or metastatic tumor spread. Complete resection of any Astler Coller stage C colorectal malignant tumor has to be followed by a 5-fluorouracil-based adjuvant chemotherapy. In these protocols, 5-fluorouracil is administered together with folinic acid or levamisole. The administration of an adjuvant chemotherapy could also be considered for stage BII diseases. As rectal cancers are characterized by high local relapse rates, their treatment should associate radiotherapy, given either post-surgery or preferentially pre-surgery, with resection and chemotherapy. Appropriate treatment of colorectal cancers thus requires a concerted multidisciplinary approach.

    Full Text Available Epithelial ovarian carcinoma is a disease with poor prognosis and high mortality among gynaecological cancers due to inaccessibility of ovary for inspection or sampling and lack of proper screening methods. Strategies to detect early ovarian cancer include estimation of serum CA-125 and transvaginal ultrasound (TVS for morphological index. Studies have shown that screening of asymptomatic average risk post-menopausal women did not show any benefit and are associated with false positive results which may lead to unnecessary surgery and resultant morbidity. The risks outweigh benefits. Present recommendation is to screen high risk women especially hereditary cancers and offer risk reducing surgery when needed. Prophylactic salpingectomy/oophorectomy may offer the opportunity to prevent ovarian cancer. More trials and more research in newer biomarkers are needed.

    Visual images play an important role in educating the public about skin cancer prevention. The objectives of this systematic review were to: 1) determine how visual images are evaluated in skin cancer and tanning qualitative research studies (including theoretical and methodological approaches) and 2) summarize and discuss the image-related findings of the studies with respect to cancer education and public health. Seven databases were searched (PubMed-MEDLINE, EMBASE, PsycINFO, Sociological Abstracts, Social Sciences Full Text, ERIC, and ABI/INFORM) using multiple search terms, including MeSH terms, resulting in 5330 citations. Studies were included if they were in English, peer-reviewed, qualitative in design or methodology, dealt with skin cancer or UV exposure, used visual images, and had a focus on the public or patients (i.e., not medical professionals). Eight studies met the inclusion criteria: seven content analyses and one focus group study. Content analysis studies in this review suggest the mass media portray Caucasian men and women as unprotected from the sun and with tanned skin, and thus, may inform behaviors related to skin cancer risk. The focus group study suggests visible minorities may benefit from the incorporation of images of melanoma on ethnic skin in cancer education materials. None of the studies used visual communication theory to explicitly guide the research, nor were standardized tools used for image assessment. The lack of guiding theory and standardized assessment instruments can introduce bias in how images are selected and used in research on skin cancer education.

  15. Pomegranate for Prevention and Treatment of Cancer: An Update

    2017-01-01

    Full Text Available Cancer is the second leading cause of death in the United States, and those who survive cancer may experience lasting difficulties, including treatment side effects, as well as physical, cognitive, and psychosocial struggles. Naturally-occurring agents from dietary fruits and vegetables have received considerable attention for the prevention and treatment of cancers. These natural agents are safe and cost efficient in contrast to expensive chemotherapeutic agents, which may induce significant side effects. The pomegranate (Punica granatum L. fruit has been used for the prevention and treatment of a multitude of diseases and ailments for centuries in ancient cultures. Pomegranate exhibits strong antioxidant activity and is a rich source of anthocyanins, ellagitannins, and hydrolysable tannins. Studies have shown that the pomegranate fruit as well as its juice, extract, and oil exert anti-inflammatory, anti-proliferative, and anti-tumorigenic properties by modulating multiple signaling pathways, which suggest its use as a promising chemopreventive/chemotherapeutic agent. This review summarizes preclinical and clinical studies highlighting the role of pomegranate in prevention and treatment of skin, breast, prostate, lung, and colon cancers.

    Full Text Available Abstract Background Downward trends have been observed in oral cancer incidence and mortality in the US over the past 30 years; however, these declines are not uniform within this population. Several studies have now demonstrated an increase in the incidence and mortality from oral cancers among certain demographic groups, which may have resulted from increased risks or risk behaviors. This study examines the underlying data that comprise these trends, to identify specific populations that may be at greater risk for morbidity and mortality from oral cancers. Methods Oral cancer incidence and mortality data analyzed for this study were generated using the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER program. Results While oral cancer incidence and mortality rates have been declining over the past thirty years, these declines have reversed in the past five years among some demographic groups, including black females and white males. Sorting of these data by state revealed that eight states exhibited increasing rates of oral cancer deaths, Nevada, North Carolina, Iowa, Ohio, Maine, Idaho, North Dakota, and Wyoming, in stark contrast to the national downward trend. Furthermore, a detailed analysis of data from these states revealed increasing rates of oral cancer among older white males, also contrary to the overall trends observed at the national level. Conclusion These results signify that, despite the declining long-term trends in oral cancer incidence and mortality nationally, localized geographic areas exist where the incidence and mortality from oral cancers have been increasing. These areas represent sites where public health education and prevention efforts may be focused to target these specific populations in an effort to improve health outcomes and reduce disparities within these populations.

    Mammography remains the mainstay of breast cancer screening. There is little controversy that mammography reduces the risk of dying from breast cancer by about 23% among women between the ages of 50 and 69 years, although the harms associated with false-positive results and overdiagnosis limit the net benefit of mammography. Women in their 70s may have a small benefit from screening mammography, but overdiagnosis increases in this age group as do competing causes of death. While new data support a 16% reduction in breast cancer mortality for 40- to 49-year-old women after 10 years of screening, the net benefit is less compelling in part because of the lower incidence of breast cancer in this age group and because mammography is less sensitive and specific in women younger than 50 years. Digital mammography is more sensitive than film mammography in young women with similar specificity, but no improvements in breast cancer outcomes have been demonstrated. Magnetic resonance imaging may benefit the highest risk women. Randomized trials suggest that self-breast examination does more harm than good. Primary prevention with currently approved medications will have a negligible effect on breast cancer incidence. Public health efforts aimed at increasing mammography screening rates, promoting regular exercise in all women, maintaining a healthy weight, limiting alcohol intake, and limiting postmenopausal hormone therapy may help to continue the recent trend of lower breast cancer incidence and mortality among American women.

    Given the number of lives affected by cancer and the great potential for optimizing well-being via lifestyle changes, patients, providers, health care systems, advocacy groups, and entrepreneurs are looking to digital solutions to enhance patient care and broaden prevention efforts. Thousands of health-oriented mobile websites and apps have been developed, with a majority focused upon lifestyle behaviors (e.g., exercise, diet, smoking). In this review, we consider the use and potential of social media and mHealth technologies for cancer prevention, cancer treatment, and survivorship. We identify key principles in research and practice, summarize prior reviews, and highlight notable case studies and patient resources. Further, with the potential for scaled delivery and broad reach, we consider application of social media and mHealth technologies in low-resource settings. With clear advantages for reach, social media and mHealth technologies offer the ability to scale and engage entire populations at low cost, develop supportive social networks, connect patients and providers, encourage adherence with cancer care, and collect vast quantities of data for advancing cancer research. Development efforts have been rapid and numerous, yet evaluation of intervention effects on behavior change and health outcomes are sorely needed, and regulation around data security issues is notably lacking. Attention to broader audiences is also needed, with targeted development for culturally diverse groups and non-English speakers. Further investment in research to build the evidence base and identify best practices will help delineate and actualize the potential of social media and mHealth technologies for cancer prevention and treatment.

    2016-08-01

    Full Text Available There is much epidemiological evidence that a diet rich in fruits and vegetables could lower the risk of certain cancers. The effect has been attributed, in part, to natural polyphenols. Besides, numerous studies have demonstrated that natural polyphenols could be used for the prevention and treatment of cancer. Potential mechanisms included antioxidant, anti-inflammation as well as the modulation of multiple molecular events involved in carcinogenesis. The current review summarized the anticancer efficacy of major polyphenol classes (flavonoids, phenolic acids, lignans and stilbenes and discussed the potential mechanisms of action, which were based on epidemiological, in vitro, in vivo and clinical studies within the past five years.

    This article is a description of the current situation in France with regard to occupational cancer: research, prevention, and occupation. Toxicologic experiments are carried out using (italic)in vitro(/italic) and (italic)in vivo(/italic) tests, particularly using transgenic mice. Several epidemiologic studies have been conducted over the last decades: population-based case-control studies; mortality studies and cancer incidence studies carried out in historical cohorts of workers employed in the industry; and case-control studies nested in occupational cohorts. French ethical aspects of toxicologic and epidemiologic studies are described. The results thus obtained are used to establish regulations for the prevention and the compensation of cancers attributable to occupational exposure. This French regulation for prevention of occupational cancer involves several partners: (italic)a(/italic)) the states authorities, including labor inspectors, responsible for preparing and implementing the labor legislation and for supervising its application, particularly in the fields of occupational health and safety and working conditions; (italic)b(/italic)) the Social Security Organisation for the analysis of present or potential occupational risks based on tests, visits in plants, complaints or requests from various sources, and statistics. These activities are performed within the framework of the general French policy for the prevention of occupational cancer. This organization includes the National Institute for Research and Safety, particularly involved in research in the various fields of occupational risks--animal toxicology, biologic monitoring, exposure measurements epidemiology, psychology, ergonomy, electronic systems and machineries, exposure to chemicals, noise, heat, vibration, and lighting; and (italic)c(/italic)) companies where the regulation defines the role of the plant manager, the occupational physician, and the Health, Safety and Working Conditions

    Many epidemiological and experimental studies have suggested that dietary fiber plays an important role in colon cancer prevention. These findings may relate to the ability of fiber to reduce the contact time of carcinogens within the intestinal lumen and to promote healthy gut microbiota, which modifies the host's metabolism in various ways. Elucidation of the mechanisms by which dietary fiber-dependent changes in gut microbiota enhance bile acid deconjugation, produce short chain fatty acids, and modulate inflammatory bioactive substances can lead to a better understanding of the beneficial role of dietary fiber. This article reviews the current knowledge concerning the mechanisms via which dietary fiber protects against colon cancer.

    Based on data obtained from the system MoZMaD - PL (Polish Mother and Child Health Monitoring System; an equivalent of the American system PRAMS (Pregnancy Risk Assessment Monitoring System). In the developed countries prevention programmes proved to be efficient in reducing morbidity and mortality due to breast and cervical cancer. In Poland, these diseases still constitute a very big problem, despite relatively easy and early diagnostics of pathological conditions preceding their development. The objective of the study was analysis of the usage of prophylactic examinations and the assessment of knowledge concerning risk factors of the development of reproductive cancers among pregnant women from rural and urban environments in Poland. The study was based on questionnaire forms within the Pregnancy Risk Assessment Monitoring System (MoZMaD - PL) implemented in Poland. The precise date of the study for the whole of Poland is announced annually by the Chief Sanitary Inspector. The questionnaire forms were correctly completed in 2010 by 2,877 women. The replies to the questions were introduced by surveyors into the MoZMaD - PL system central database managed by the Institute of Agricultural Medicine in Lublin. The results obtained were subjected to statistical analysis. The studies of pregnant women in Poland showed that the situation with respect to the performance of prevention examinations for cervical cancer was significantly worse among rural than urban women. Pregnant women from both rural and urban areas very rarely had breast USG performed. Awareness concerning cervical cancer risk factors was lower among rural than urban women. Also, knowledge concerning the examinations which should be performed for the prevention of breast cancer was poorer among rural, compared to urban women. The recognition of the attitudes of women at reproductive age towards prevention examinations is necessary in order to effectively plan health education and social health promotion

    Cancer remains to be one of the leading causes of death in the United States and around the world. The advent of modern drug-targeted therapies has undeniably improved cancer patients' cares. However, advanced metastasized cancer remains untreatable. Hence, continued searching for a safer and more effective chemoprevention and treatment is clearly needed for the improvement of the efficiency and to lower the treatment cost for cancer care. Cancer chemoprevention with natural phytochemical compounds is an emerging strategy to prevent, impede, delay, or cure cancer. This review summarizes the latest research in cancer chemoprevention and treatment using the bioactive components from natural plants. Relevant molecular mechanisms involved in the pharmacological effects of these phytochemicals are discussed. Pharmaceutical developmental challenges and opportunities in bringing the phytochemicals into the market are also explored. The authors wish to expand this research area not only for their scientific soundness, but also for their potential druggability.

    Full Text Available Background: Cervical cancer remains the leading cause of cancer death among women in sub-Saharan Africa. In Malawi, very few women have undergone screening and the incidence of cervical cancer is on the increase as is the case in most developing countries. We aimed at exploring and documenting health system gaps responsible for the poor performance of the cervical cancer prevention program in Malawi. Design: The study was carried out in 14 randomly selected districts of the 29 districts of Malawi. All cervical cancer service providers in these districts were invited to participate. Two semi-structured questionnaires were used, one for the district cervical cancer coordinators and the other for the service providers. The themes of both questionnaires were based on World Health Organization (WHO health system frameworks. A checklist was also developed to audit medical supplies and equipment in the cervical cancer screening facilities. The two questionnaires together with the medical supplies and equipment checklist were piloted in Chikwawa district before being used as data collection tools in the study. Quantitative data were analyzed using STATA and qualitative in NVIVO. Results: Forty-one service providers from 21 health facilities and 9 district coordinators participated in the study. Our findings show numerous health system challenges mainly in areas of health workforce and essential medical products and technologies. Seven out of the 21 health facilities provided both screening and treatment. Results showed challenges in the management of the cervical cancer program at district level; inadequate service providers who are poorly supervised; lack of basic equipment and stock-outs of basic medical supplies in some health facilities; and inadequate funding of the program. In most of the health facilities, services providers were not aware of the policy which govern their work and that they did not have standards and guidelines for cervical

    Obesity, diet and physical inactivity are risk factors for some cancers. Grantees of the National Comprehensive Cancer Control Program (NCCCP) in US states, tribes, and territories develop plans to coordinate funding and activities for cancer prevention and control. Including information and goals related to nutrition and physical activity (NPA) is a key opportunity for primary cancer prevention, but it is currently unclear to what extent NCCCP plans address these issues. We reviewed 69 NCCCP plans and searched for terms related to NPA. Plans were coded as (1) knowledge of NPA and cancer link; (2) goals to improve NPA behaviors; and (3) strategies to increase healthy NPA activities, environments, or systems changes. NPA content was consistently included in all cancer plans examined across all years. Only 4 (6 %) outlined only the relationship between NPA and cancer without goals or strategies. Fifty-nine plans (89 %) contained goals or strategies related to NPA, with 53 (82 %) including both. However, numbers of goals, strategies, and detail provided varied widely. All programs recognized the importance of NPA in cancer prevention. Most plans included NPA goals and strategies. Increasing the presence of NPA strategies that can be modified or adapted appropriately locally could help with more widespread implementation and measurement of NPA interventions.

    Cancer has become the first leading cause of death in the world, particularly in low- and middle-income countries. Facing the increasing trend of cancer incidence and mortality, China issued and implemented "three-early (early prevention, early diagnosis and early treatment)" national cancer prevention plan. As the main body and dependence of social governance, non-governmental organizations (NGOs) take over the role of government in the field of cancer prevention and treatment. American Cancer Society (ACS) made a research on cancer NGOs and civil society in cancer control and found that cancer NGOs in developing countries mobilize civil society to work together and advocate governments in their countries to develop policies to address the growing cancer burden. Union for International Cancer Control (UICC), Cancer Council Australia (CCA), and Malaysian cancer NGOs are the representatives of cancer NGOs in promoting cancer control. Selecting Chinese Anti-Cancer Association (CACA) as an example in China, this article is to investigate how NGOs undertake systematic cancer prevention work in China. By conducting real case study, we found that, as a NGO, CACA plays a significant role in intensifying the leading role of government in cancer control, optimizing cancer outcomes, decreasing cancer incidence and mortality rates and improving public health.

    Full Text Available Background: Cervical cancer which affects relatively young women of child bearing age is considered to be the second most common cancer in women and a leading cause of cancer-related deaths in developing countries, a reflection of global health inequity. There are more than 450,000 newly diagnosed cases annually with over a quarter of million deaths recorded out of which over 80 percent are from the developing countries especially Africa, South Asia, South and Central America, and the Caribbean, with an exponential rise expected from this figure by 2020. The preventive measures available (Pap smear and HPV vaccine aimed at reducing morbidity and mortality associated with this disease, has been shown to be very effective but difficult to implement especially in the developing countries partly due to lack of resources and mainly lack of government commitment amongst other things. This forms the basis of this review to look at the position of HPV vaccine in the prevention of cancer of the cervix. Method: In the course of this write-up, relevant literatures were reviewed using manual library search, relevant websites and internet articles. The key words employed were: cervical cancer, human papilloma virus, pap smear and vaccination. Results: It has been shown that, where resources permits, combining HPV vaccine in combination with pap smear screening methods especially to high risk group would greatly reduce the morbidity and mortality associated with cancer of the cervix. Conclusion: Although there are so many essential questions still unanswered, considering the havoc caused by this preventable gynaecological malignancy and coupled with the ever increasing costs of its treatment, the advantages of using HPV vaccine in addition to routine Pap smear as a means of preventing cancer of the cervix greatly outweighs the disadvantages. However, there is the need for caution to be adhered to when it comes to large scale vaccination programs in view of

    Based on our initial work with green tea, in which repeated topical applications of (-)-epigallocatechin gallate (EGCG), the main green tea polyphenol, inhibited tumor promotion in a two-stage carcinogenesis experiment on mouse skin (Phytother Res 1, 44-47, 1987), numerous scientists have since provided so much additional evidence of the benefits of drinking green tea that it is now an acknowledged cancer preventive in Japan, and will possibly soon be recognized as such in other countries. Our work has so far produced several important results with EGCG and green tea: a wide range of target organs in animal experiments for cancer prevention, wide bioavailability of 3H-EGCG in various organs of mice, delayed cancer onset of patients with a history of consuming over 10 cups of green tea per day, and absence of any severe adverse effects among volunteers who took 15 green tea tablets per day (2.25 g green tea extracts, 337.5 mg EGCG, and 135 mg caffeine) for 6 months. This paper introduces three new findings: 1) EGCG interacted with the phospholipid bilayer membrane resulting in confirmation of the sealing effect of EGCG; 2) EGCG inhibited TNF-alpha gene expression in the cells and TNF-alpha release from the cells; 3) high consumption of green tea was closely associated with decreased numbers of axillary lymph node metastases among premenopausal Stage I and II breast cancer patients, and with increased expression of progesterone and estrogen receptors among postmenopausal ones. These results provide new insights into our understanding of the mechanisms of action of tea polyphenols and green tea extract as a cancer preventive.

    2014-12-01

    Diet has been linked to the prevention of colorectal cancer (CRC) and may explain some of the differences in incidence and mortality among various populations. Evidence suggests that a high intake of red and processed meats is associated with an increased risk of CRC. The protective benefits of fiber are unclear, although in some studies fiber is associated with reduced CRC risk. The role of supplements, such as calcium, vitamin D, and folic acid, remains uncertain, and these nutrients cannot be currently recommended for chemoprevention. Obesity and sedentary lifestyle have been associated with an increased risk for colon cancer. Because of the inherent difficulty in studying the effects of specific nutrients, dietary pattern analysis may be a preferable approach to the investigation of the relationship between diet and risk for human diseases. Lifestyle modifications, such as increasing physical activity and consumption of a diet rich in fiber, fruits, vegetables, fish, and poultry and low in red and processed meats, have been advocated for primary prevention of several chronic diseases, and may in fact be beneficial for cancer prevention, particularly CRC.

The protective effects of habitual continuous energy restriction (CER) and weight loss on breast tumour formation have been conclusively demonstrated in animal studies over the past 100 years, and more recently in women using data from observational studies and bariatric surgery. Intermittent energy restriction (IER) and intermittent fasting (IF) are possible alternative preventative approaches which may be easier for individuals to undertake and possibly more effective than standard CER. Here, we summarise the available data on CER, IER and IF with special emphasis on their potential for breast cancer prevention. In animals, IER is superior or equivalent to CER with the exception of carcinogen-induced tumour models when initiated soon after carcinogen exposure. There are no human data on IER and breast cancer risk, but three studies demonstrated IER and CER to be equivalent for weight loss. IF regimens also reduce mammary tumour formation in animal models and also led to weight loss in human subjects, but have not been directly compared with CER. Animal and some human data suggest that both IER and IF may differ mechanistically compared with CER and may bring about greater reduction in hepatic and visceral fat stores, insulin-like growth factor 1 (IGF-1) levels and cell proliferation, and increased insulin sensitivity and adiponectin levels. Although IER and IF were first studied 65 years ago, we conclude that further studies are required to assess their values compared with CER.

    Exposure to ultraviolet radiation from indoor tanning devices (tanning beds, booths, and sun lamps) or from the sun contributes to the risk of skin cancer, including melanoma, which is the type of skin cancer responsible for most deaths. Indoor tanning is common among certain groups, especially among older adolescents and young adults, adolescent girls and young women, and non-Hispanic whites. Increased understanding of the health risks associated with indoor tanning has led to many efforts to reduce use. Most environmental and systems efforts in the U.S. (e.g., age limits or requiring parental consent/accompaniment) have occurred at the state level. At the national level, the U.S. Food and Drug Administration and the Federal Trade Commission regulate indoor tanning devices and advertising, respectively. The current paper provides a brief review of (1) the evidence on indoor tanning as a risk factor for skin cancer; (2) factors that may influence use of indoor tanning devices at the population level; and (3) various environmental and systems options available for consideration when developing strategies to reduce indoor tanning. This information provides the context and background for the companion paper in this issue of the American Journal of Preventive Medicine, which summarizes highlights from an informal expert meeting convened by the CDC in August 2012 to identify opportunities to prevent skin cancer by reducing use of indoor tanning devices.

    Full Text Available Abstract Background Colorectal cancer represents the most common malignancy of the gastrointestinal tract. Owing to differences in dietary habits and lifestyle, this neoplasm is more common in industrialized countries than in developing ones. Evidence from a wide range of sources supports the assumption that the link between diet and colorectal cancer may be due to an imbalance of the intestinal microflora. Discussion Probiotic bacteria are live microorganisms that, when administered in adequate amounts, confer a healthy benefit on the host, and they have been investigated for their protective anti-tumor effects. In vivo and molecular studies have displayed encouraging findings that support a role of probiotics in colorectal cancer prevention. Summary Several mechanisms could explain the preventive action of probiotics against colorectal cancer onset. They include: alteration of the intestinal microflora; inactivation of cancerogenic compounds; competition with putrefactive and pathogenic microbiota; improvement of the host’s immune response; anti-proliferative effects via regulation of apoptosis and cell differentiation; fermentation of undigested food; inhibition of tyrosine kinase signaling pathways.

    AIM: To evaluate the preliminary effects of comprehensive prevention of gastric cancer in Zhuanghe County epidemiologically.METHODS: Stratified sampling and cluster sampling were applied to define the intervention group and the control group. The prospective cohort study was used for evaluating the effect of preventing gastric cancer. The relative risk (RR)and attributable risk percent (AR %) of intervention on gastric cancer death were calculated. Potential years of life lost (PLYY) of the disease was analyzed, and the RR and AR %of PYLL were calculated. Survival analysis was applied among the screened patients.RESULTS: In the first 4 years after intervening, the relative risk (RR) of intervention on death was 0.5059 (95 % CI:0.3462~0.7392,P<0.05) with significance statistically. AR %of the intervention on death was 49.41%. The RR of intervention on cumulative PYLL was 0.6778 (95 % CI:0.5604~0.8198,P<0.05) with statistic significance. AR %of the intervention on cumulative PYLL was 30.32 %. The four-year survival rate of the screened patients was 0.6751(95 % CI: 0.5298~0.9047).CONCLUSION: The initiative intervention results showed that the intervention approach used in the trial was effective, it reduced mortality and increased survival rate, and alleviated the adverse effect of gastric cancer on the health and life of screened population.

  4. Potential Mechanisms of Cancer Prevention by Weight Control

    Science.gov (United States)

    Jiang, Yu; Wang, Weiqun

    Weight control via dietary caloric restriction and/or physical activity has been demonstrated in animal models for cancer prevention. However, the underlying mechanisms are not fully understood. Body weight loss due to negative energy balance significantly reduces some metabolic growth factors and endocrinal hormones such as IGF-1, leptin, and adiponectin, but enhances glucocorticoids, that may be associated with anti-cancer mechanisms. In this review, we summarized the recent studies related to weight control and growth factors. The potential molecular targets focused on those growth factors- and hormones-dependent cellular signaling pathways are further discussed. It appears that multiple factors and multiple signaling cascades, especially for Ras-MAPK-proliferation and PI3K-Akt-anti-apoptosis, could be involved in response to weight change by dietary calorie restriction and/or exercise training. Considering prevalence of obesity or overweight that becomes apparent over the world, understanding the underlying mechanisms among weight control, endocrine change and cancer risk is critically important. Future studies using "-omics" technologies will be warrant for a broader and deeper mechanistic information regarding cancer prevention by weight control.

    The cancer-preventive effects of green tea and its main constituent (-)-epigallocatechin gallate [(-)-EGCG] are widely supported by results from epidemiological, cell culture, animal and clinical studies in the recent decade. In vitro cell culture studies show that tea polyphenols potently induce apoptotic cell death and cell cycle arrest in tumor cells but not in their normal cell counterparts. Green tea polyphenols affect several signal transduction pathways, including growth factor-mediated, the mitogen-activated protein kinase (MAPK)-dependent, and ubiquitin/proteasome degradation pathways. Epidemiological studies have suggested that the consumption of green tea lowers the risk of cancer. Various animal studies have revealed that treatment by green tea inhibits tumor incidence and multiplicity in different organ sites such as skin, lung, liver, stomach, mammary gland and colon. Phase I and II clinical trials were carried out recently to explore the anticancer effects of green tea in patients with cancer. At this time, more mechanistic research, animal studies, and clinical trials are necessary to further evaluate the role of green tea in cancer prevention.

    Helicobacter pylori (H. pylori), which increases the risk of gastric diseases, including digestive ulcers and gastric cancer, is highly prevalent in Asian countries. There is no doubt that eradication of the bacterium is effective as a treatment of digestive ulcer, but eradication aiming to reduce the gastric cancer risk is still controversial. Observational studies in Japan demonstrated that the eradication decreased the gastric cancer risk among 132 stomach cancer patients undergoing endoscopical resection (65 treated with omeprazol and antibiotics and 67 untreated). In Columbia, 976 participants were randomized into eight groups in a three-treatment factorial design including H. pylori eradication, resulting in significant regression in the H. pylori eradication group. A recent randomized study in China also showed a significant reduction of gastric cancer risk among those without any gastric atrophy, intestinal metaplasia, and dysplasia. Efficacy of eradication may vary in extent among countries with different incidence rates of gastric cancer. Since the lifetime cumulative risk (0 to 84 years old) of gastric cancer in Japan is reported to be 12.7% for males and 4.8% for females (Inoue and Tominaga, 2003), the corresponding values for H. pylori infected Japanese can be estimated at 21.2% in males and 8.0% in females under the assumptions that the relative risk for infected relative to uninfected is 5 and the proportion of those infected is 0.5. Both the fact that not all individuals are infected among those exposed and the knowledge that only a small percentage of individuals infected with the bacterium develop gastric cancer, indicate the importance of gene-environment interactions. Studies on such interactions should provide useful information for anti-H. pylori preventive strategies.

    Full Text Available Introduction: Cervical cancer is a serious problem in gynaecological oncology, which gains even more importance when it concerns young women at reproductive age – 20–39. It is an alarming fact that despite the knowledge about causes of the development of the disease, its dynamics, diagnostic and treatment methods, in Poland, very high mortality rates are still observed, compared to the other countries of the European Union. Aim of the research : To evaluate health behaviours of women with respect to cervical cancer prophylaxis. Material and methods: The study included 115 women aged 20 to 50, and was conducted in the Regional Mother and Newborn Child Centre in Kielce by the method of a diagnostic survey. The research instrument was a questionnaire consisting of 28 items designed by the author. Results : Analysis of the results of the study showed that 17.39% of respondents initiated sexual activity when aged under 18. The examined women had a relatively good knowledge of the basic cervical cancer risk factors. Among the main cervical cancer risk factors, 80.00% of respondents mentioned infection with HPV virus. Conclusions : Health behaviours of women with respect to cervical cancer prophylaxis are becoming increasingly positive. However, educational actions should be enhanced concerning detailed information pertaining to cervical cancer and benefits resulting from vaccination against HPV virus.

    2017-05-01

    As the interest in graphic medicine grows, health communicators have started engaging readers with compelling visual and textual accounts of health and illness, including via comic books. One context where comics have shown promise is cancer communication. This brief report presents an early example of graphic medicine developed by the American Cancer Society. "Ladies … Wouldn't It Be Better to Know?" is a comic book produced in the 1960s to provide the public with lay information about the Pap test for cervical cancer prevention and detection. An analysis of a key narrative attribute, plot development, illustrates the central role that perceived barriers played in this midcentury public health message, a component that remains a consideration of cancer communication design today. This case study of an early graphic narrative identifies promising cancer message features that can be used to address and refute barriers to cervical cancer screening and connects contemporary research with historical efforts in public health communication.

    Full Text Available Background and Objectives: Report educational experiences orienting the elderly population about sexuality and prevention of sexually transmitted diseases. Case description: A professional experience report of STD prevention group in the elderly at a specialized clinic. The educational gerontology was used as a methodology in the production of workshops held from November/2012 to December/2014 to service users. The workshops entitled “Tenda da Sabedoria”, “Baile dos Idosos” and “Roda de Conversa”addressed the sexuality of the elderly, knowledge about transmission and how to prevent it. Actions are always accompanied by the distribution of educational materials, condoms and referrals to testing users for Hepatitis B and C, HIV and syphilis. The group noticed satisfaction of the elderly, interest and effective participation through learning in a simple and enjoyable way. It was also possible to identify elderly interested in multiplying the knowledge with peers and family. Conclusions: The participatory educational process promotes strengthening of elderly network support, enabling an active channel of communication between staff and users, offering subsidies appropriated to prevention work and treatment of diseases.

    The National Action Plan for Non-communicable Diseases Prevention, Control and Health Promotion in Pakistan (NAP-NCD) integrates prevention and control of cancers with a comprehensive NCD prevention framework with a specific emphasis on tobacco, diet and physical activity as cross-cutting risks. The programme prioritizes on sustainable institutional support for mature cancer registries in order to facilitate cancer surveillance; prevention of cancers and early detection as part of an integrated NCD behavioural change communication strategy and building capacity in the health system for cancer prevention and control. The programme's research agenda also includes appropriate studies to bridge critical gaps in evidence relating to appropriate and cost-effective strategies for preventing common cancers in Pakistan. To contain exposure to carcinogenic agents in the environment and in worksites, NAP-NCD stresses on the transparent enforcement of National Environmental Quality Standards; the institution to take proactive measures to contain potential risks to cancers in industrial settings; stricter enforcement of labour laws, stringent regulations governing chemical handling and the active incorporation of preventive health in the mandate of organizations providing health coverage for the labour workforce. It has also been deemed essential to study cancer trends in defined industrial settings at high-risk and to identify causal associations in order to delineate precise targets for preventive interventions in the native setting. NAP-NCD stresses on the development of institutional mechanisms with a regulatory function for cancer control; these include a National Cancer Control Council, with the mandate to uphold ethics and principles and guidelines on technical matters and a National Occupational Safety and Health Association. The Plan also prioritizes on pain relief and palliative care alongside prevention and control efforts and stresses on the need to integrate

    Background In the U.S., breast cancer accounts for more cancer deaths in women than any site other than lung cancer. Based upon attributable risks, about 30–35% of breast cancers could potentially be prevented by addressing obesity, physical inactivity, increased alcohol consumption, and carcinogenic exposures such as hormone replacement therapy (HRT). We need methods of reducing women’s risks of this disease that are attractive and easy to use, widely accessible to diverse women, and able to be easily amended to account for new research. Methods The overall objective of this 12-month project is to develop and test a smartphone app to provide women with information about how they can reduce their risk of breast cancer through healthy behaviors such as physical activity, weight management, restricting caloric intake, consuming a healthy diet and proper nutrition, engaging in regular physical activity, and avoiding carcinogenic exposures such as HRT and alcohol. The specific aims are: (I) to develop a smartphone app for breast cancer prevention using a behavioral framework; (II) to ensure interconnectivity with commercially available products (Fitbit device for monitoring physical activity and the LoseIt! smartphone app for monitoring and tracking diet and nutrition); and (III) to ensure that the mHealth intervention is suitable for women with varying levels of health literacy and eHealth literacy. Results The app, referred to as Physical activity and Your Nutrition for Cancer (PYNC), is being coded on an iOS platform. Users will be able to access the breast cancer prevention app using their smartphone or tablet. The app’s design will ensure interconnectivity with commercially available products for monitoring and tracking physical activity, caloric intake, diet and nutrition.

    2010-01-01

    In the United States about 17% of adolescents meet diagnostic criteria for mental, emotional, and behavioral disorders. Six million young people receive treatment services annually for mental, emotional, or behavioral problems. These problems affect 1 in 5 families and cost $247 million annually (O'Connell, Boat, & Warner, 2009). Some strategies for preventing mental, emotional, and behavioral disorders in young people have been developed, tested, and found to be effective in preventing the onset, persistence, and severity of psychological disorders, drug abuse, and delinquency. Unfortunately, tested and effective prevention policies, programs, and practices are not widely used (O'Connell, Boat, & Warner, 2009). This paper highlights recent advances in prevention science and describes some opportunities and challenges in advancing the use of science-based prevention in communities. The chapter concludes by exploring the potential role of social work education in developing a workforce ready to increase community access to effective prevention strategies.

    The American Cancer Society (ACS) publishes behavioral guidelines for cancer prevention, including standards on body weight, physical activity, nutrition, alcohol, and tobacco use. The impact of these guidelines has been rarely studied in low-income and African American populations. The study included 61,098 racially diverse, mainly low-income adults who participated in the Southern Community Cohort Study and were followed for a median of 6 years. Cox models were used to estimate HRs for cancer incidence associated with behaviors and with an ACS physical activity/nutrition 0-to-4 compliance score indicating the number of body weight, physical activity, healthy eating, and alcohol guidelines met. During the study period, 2,240 incident cancers were identified. Significantly lower cancer incidence was found among never smokers and non/moderate alcohol drinkers, but not among those meeting guidelines for obesity, physical activity, and diet. The ACS compliance score was inversely associated with cancer risk among the 25,509 participants without baseline chronic disease. HRs for cancer incidence among those without baseline chronic diseases and who met one, two, three, or four guidelines versus zero guidelines were 0.93 (95% confidence intervals, 0.71-1.21), 0.85 (0.65-1.12), 0.70 (0.51-0.97), and 0.55 (0.31-0.99), respectively. Associations were consistent in analyses stratified by sex, race, household income, and smoking status. Meeting the ACS smoking and body weight/physical activity/dietary/alcohol guidelines for cancer prevention is associated with reductions in cancer incidence in low-income and African American populations. This study provides strong evidence supporting lifestyle modification to lower cancer incidence in these underserved populations.

    The purpose of this study was to examine the breast cancer prevention information seeking behaviors among rural women, the prevalence of Internet, cell, and text use, and interest to receive breast cancer prevention information cell and text messages. While growing literature for breast cancer information sources supports the use of the Internet, little is known about breast cancer prevention information seeking behaviors among rural women and mobile technology. Using a cross-sectional study design, data were collected using a survey. McGuire's Input-Ouput Model was used as the framework. Self-reported data were obtained from a convenience sample of 157 women with a mean age of 60 (SD = 12.12) at a rural New Mexico imaging center. Common interpersonal information sources were doctors, nurses, and friends and common channel information sources were television, magazines, and Internet. Overall, 87% used cell phones, 20% had an interest to receive cell phone breast cancer prevention messages, 47% used text messaging, 36% had an interest to receive text breast cancer prevention messages, and 37% had an interest to receive mammogram reminder text messages. Bivariate analysis revealed significant differences between age, income, and race/ethnicity and use of cell phones or text messaging. There were no differences between age and receiving text messages or text mammogram reminders. Assessment of health information seeking behaviors is important for community health educators to target populations for program development. Future research may identify additional socio-cultural differences.

    Mortality rate for breast cancer is higher among African American (AA) women than for women of other racial/ethnic groups. Obesity, also higher among AA women, may increase the risk of breast cancer development and recurrence. Lifestyle factors such as healthy nutrition can reduce the rate of obesity and breast cancer. This study examined the determinants of adherence to nutrition-related cancer prevention guidelines among AA breast cancer survivors. AA breast cancer survivors (n=240) were recruited from a breast cancer support group to complete a lifestyle assessment tool for this cross-sectional study. Chi-square test and ordinal logistic regression analysis were used to examine the relationship between adherence to nutrition-related cancer prevention guidelines and potential predictors of adherence. Majority of the survivors met the guideline for red and processed meat (n=191, 83.4%), but did not meet the guideline for fruits and vegetables (n=189, 80.4%). For survivors with annual household incomes $50,000 (OR= 0.25, 95% CI: 0.08, 0.80). Poor physical functioning (OR= 38.48, 95% CI: 2.26, 656.58), sleep disturbances (OR= 60.84, 95% CI: 1.61, 2296.02), and income > $50,000 (OR= 51.02, 95% CI: 1.13, 2311.70) were associated with meeting the guideline for red and processed meat. Many AA breast cancer survivors are not meeting the nutrition-related cancer prevention guidelines. For this population, more interventions that enhance access to and consumption of healthy diets are needed.

The project was a collaborative effort of the Maine Cancer Consortium, American Cancer Society (ACS, and the City of Portland, Health and Human Services Department, Public Health Division. Portland, Me, served as the pilot site. The National Cancer Institute (NCI defines skin cancer as a disease in which abnormal cells divide uncontrollably in the outer layers of the skin (1. The American Cancer Society's Facts and Figures 2001 (the latest year for which these figures are available estimated that more than 1 million cases of highly curable basal cell or squamous cell cancers would be diagnosed in the United States that year (2. An estimated 9800 U.S. deaths from cancer were projected as well: 7800 from melanoma, the most serious form of skin cancer, and 2000 from other skin cancers. Melanoma was expected to be diagnosed in about 51,400 Americans in 2001. The incidence rate of melanoma has increased about 3% per year on average since 1981. In 2002, NCI announced that researchers showed for the first time that individual risk of melanoma is associated with the intensity of sunlight that a person receives over a lifetime (3. Target audiences for our program were newborns and their parents, children between 5 and 14 years old and their caregivers, and all people living in the Portland area. Protecting skin from excess sun exposure during childhood and adolescence is important in reducing the risk of all types of skin cancer during adulthood. From our anecdotal evidence, many parents of newborns are unaware that sunscreen is not recommended for babies under 6 months of age, and they need better information about how to protect their newborns from the sun. Teaching children and their caregivers to follow ACS guidelines will help protect their skin for years to come. It will also help children to develop healthy

    Most patients suffering from cancer die of metastatic disease. Surgical removal of solid tumors is performed as an initial attempt to cure patients; however, surgery is often accompanied with trauma, which can promote early recurrence by provoking detachment of tumor cells into the blood stream or inducing systemic inflammation or both. We have previously reported that administration of atrial natriuretic peptide (ANP) during the perioperative period reduces inflammatory response and has a prophylactic effect on postoperative cardiopulmonary complications in lung cancer surgery. Here we demonstrate that cancer recurrence after curative surgery was significantly lower in ANP-treated patients than in control patients (surgery alone). ANP is known to bind specifically to NPR1 [also called guanylyl cyclase-A (GC-A) receptor]. In mouse models, we found that metastasis of GC-A-nonexpressing tumor cells (i.e., B16 mouse melanoma cells) to the lung was increased in vascular endothelium-specific GC-A knockout mice and decreased in vascular endothelium-specific GC-A transgenic mice compared with control mice. We examined the effect of ANP on tumor metastasis in mice treated with lipopolysaccharide, which mimics systemic inflammation induced by surgical stress. ANP inhibited the adhesion of cancer cells to pulmonary arterial and micro-vascular endothelial cells by suppressing the E-selectin expression that is promoted by inflammation. These results suggest that ANP prevents cancer metastasis by inhibiting the adhesion of tumor cells to inflamed endothelial cells.

    Secondary metabolites of higher plants exert numerous effects on tumorigenesis, on tumor cells in vitro, tumors in experimental animals in vivo, interact with anti-cancer drugs, thus affecting positively or negatively their efficacy, and protect normal tissues of the host organism against adverse effects of anti-cancer therapies. The industrial development of pharmaceutical and nutraceutical products based on secondary plant metabolites is limited due to the following: (i) limited availability of their natural sources, (ii) concern about rare extinguishing plants, (iii) unavoidable contamination of plant extracts with environmental pollutants, (iv) seasonal variations in plant harvesting, (v) poor standardization of the final product due to variable conditions for plant growth, and (vi) difficulties of secondary metabolite extraction from the parts of grown plant. There is now steadily growing interest in the biotechnological approach to produce secondary metabolites using plant cell or plant tissue cultures. In the present review, biosynthesis of secondary metabolites and their role(s) in plant physiology will be briefly discussed; the biotechnological approach to active substances production in the plant cell and plant tissue cultures will be described; examples and mechanisms of cancer preventive and anti-cancer action of some biotechnologically produced plant metabolites will be provided; and future perspectives for biotechnologically produced plant-derived substances in the combined protocols for cancer treatment will be suggested.

    Bone metastases and skeletal complications are major causes of morbidity in prostate cancer patients. Despite the osteoblastic appearance of bone metastases on imaging studies, patients have elevated serum and urinary markers of bone resorption, indicative of high osteoclast activity. Increased osteoclast activity is independently associated with higher risk of subsequent skeletal complications, disease progression, and death. Osteoclast-targeted therapies are therefore a rational approach to reduction of risk for disease-related skeletal complications, bone metastases, and treatment-related fractures. This review focuses on recent advances in osteoclast-targeted therapy in prostate cancer. Bisphosphonates have been extensively studied in men with prostate cancer. Zoledronic acid significantly decreased the risk of skeletal complications in men with castration-resistant prostate cancer and bone metastases, and it is FDA-approved for this indication. Denosumab is a human monoclonal antibody that binds and inactivates RANKL, a critical mediator of osteoclast differentiation, activation, and survival. Recent global phase 3 clinic trials demonstrated an emerging role for denosumab in the treatment of prostate cancer bone metastases and prevention of fractures associated with androgen deprivation therapy.

    Green tea contains high concentrations of tea polyphenols that have shown inhibitory effects against the development, progress, and growth of carcinogen-induced tumors in animal models at different organ sites, including the esophagus and lung. Green tea polyphenols also have shown to suppress cell proliferation and induce apoptosis. Besides antioxidative property, green tea polyphenols have pro-oxidative activities under certain conditions and modulate phase II metabolic enzymes that can enhance the detoxification pathway of environmental toxicants and carcinogens. Although epidemiological studies have provided inconclusive results on the effect of green tea consumption against the development of esophageal and lung cancers in humans overall, the inverse association between green tea intake and risk of esophageal cancer risk is more consistently observed in studies with adequate control for potential confounders. Epidemiological studies also have demonstrated an inverse, albeit moderate, association between green tea consumption and lung cancer, especially in non-smokers. This article reviews data on the cancer-preventive activities of green tea extract and green tea polyphenols and possible mechanisms against the esophageal and lung carcinogenesis in experimental animals, and summarizes the current knowledge from epidemiological studies on the relationship between green tea consumption and esophageal and lung cancer risk in humans.

    Colorectal cancer is the third most prevalent cancer in the world. If detected at an early stage, treatment often might lead to cure. As prevention is better than cure, epidemiological studies reveal that having a healthy diet often protects from pro-moting/developing cancer. An important consideration in evaluating new drugs and devices is determining whether a product can effectively treat a targeted disease. There are quite a number of biomarkers making their way into clinical trials and few are awaiting the preclinical efficacy and safety results to enter into clinical trials. Researchers are facing challenges in modifying trial design and defining the right control population, validating biomarker assays from the bio-logical and analytical perspective and using biomarker data as a guideline for decision making. In spite of following all guidelines, the results are disappointing from many of the large clinical trials. To avoid these disappointments, selection of biomarkers and its target drug needs to be evaluated in appropriate animal models for its toxicities and efficacies. The focus of this review is on the few of the potential molecular targets and their biomarkers in colorectal cancers. Strengths and limitations of biomarkers/surrogate endpoints are also discussed. Various pathways involved in tumor cells and the specific agents to target the altered molecular biomarkerin biomolecular pathwayare elucidated. Importance of emerging new platforms siRNAs and miRNAs technology for colorectal cancer therapeutics is reviewed.

    Cancer is primarily an "old-age" disease that has an "age-old" history. The overall incidence of cancer is much higher in Western countries, but is rapidly growing in Eastern countries perhaps due to change in life-style. Almost three million studies published to date indicate that cancer is a hyperproliferative disorder that arises from dysregulation of multiple cell signaling pathways. The cancer genome landscape indicates that approximately 140 genes and 12 cell signaling pathways drive almost all cancers. "Targeted therapy," a buzz word in cancer treatment for the past two decades, has provided antibodies, as well as small-molecule inhibitors. These therapies have been successful only in few instances. However, in most cases, minor increase in overall survival has been reported at the cost of huge expense. An alternative strategy is to prevent cancer or to diagnose and treat the disease at an early stage to gain survival benefits. Such interventions are also cost-effective. To address some of these issues, the 6th International Translational Cancer Research Conference was held during February 4-7th, 2016, in Ahmedabad, Gujarat, India; the homeland of Mahatma Gandhi. This conference was focused on utilizing multidisciplinary approaches for prevention and early treatment that would likely simultaneously or sequentially target many key pathways. Several distinguished speakers were invited from around the world. This article highlights primary features of this conference.

    Full Text Available Abstract Options for the prevention of hereditary breast and ovarian cancer include screening, preventive surgery and chemoprevention. Screening studies with magnetic resonance imaging of the breast are promising but the technology is not widespread and MRI is unlikely to be available as a screening tool in the near future. Prophylactic oophorectomy and mastectomy are effective preventive measures and are gaining in acceptance by patients and physicians. Preventive mastectomy is effective against both primary and contralateral breast cancer. Oophorectomy prevents ovarian cancer, and if done prior to menopause, will prevent breast cancer as well. Tamoxifen has been shown to prevent contralateral breast cancers in BRCA1 and BRCA2 carriers but is not widely accepted as a means of primary prevention. Oral contraceptives and tubal ligation will reduce the risk of hereditary ovarian cancer and should be considered in women who wish to retain ovarian function.

    This study evaluated effects of a key session from a nationally recognized drug abuse prevention program on basic memory processes in 211 high-risk youth in Southern California. In a randomized, between-subject design, the authors manipulated assignment to a Myth and Denial program session and the time of assessment (immediate vs. one-week delay). The authors examined program decay effects on memory accessibility and judgment errors. Those participants exposed to the program session generated more myths and facts from the program than those in the control group, suggesting that even a single program session influenced students’ memory for program information and this was retained at least one week and detectable with indirect tests of memory accessibility. However, consistent with basic research perspectives, participants in the program delayed assessment group erroneously generated more fact-related information from the session to the prompt “It is a myth that_____” than the participants in the program immediate assessment group; that is, they retained more facts as myths. These types of program effects, anticipated by basic memory theory, were not detected with a traditional judgment task in the present sample. The results suggest that basic science approaches offer a novel way of conceptually recasting prevention effects to more completely understand how these effects may operate. Implications for program evaluation and conceptualization are discussed. PMID:22544598

    The International Agency for Research on Cancer classified both outdoor air pollution and airborne particulate matter as carcinogenic to humans (Group 1) for lung cancer. There may be associations with cancer at other sites; however, the epidemiological evidence is limited. The aim of this study was to clarify whether ambient air pollution is associated with specific types of cancer other than lung cancer by examining associations of ambient air pollution with nonlung cancer death in the Cancer Prevention Study II (CPS-II). Analysis included 623,048 CPS-II participants who were followed for 22 y (1982-2004). Modeled estimates of particulate matter with aerodynamic diameter pollutant models including PM2.5 and NO2 and in three-pollutant models with O3. We observed no statistically significant positive associations with death from other types of cancer based on results from adjusted models. The results from this large prospective study suggest that ambient air pollution was not associated with death from most nonlung cancers, but associations with kidney, bladder, and colorectal cancer death warrant further investigation. https://doi.org/10.1289/EHP1249.

    Cancer mortality in Japan is forecasted to become high; thus, learning about cancer, cancer prevention, and cancer treatment will be indispensable for the Japanese. Recognition of the increasing rates of cancer has initiated a discussion regarding the introduction of cancer education into the regular educational curriculum for the younger generation. The importance of cancer education is noww idely recognized, and the 2nd Basic Plan to Promote Cancer Control Programs is directed at early initiation of education. The Ministry of Education, Culture, Sports, Science and Technology is nowreview ing the detailed plan, with an intention to draw a conclusion by the end of the 2016 business year. However, ongoing debates have revealed that there are many obstacles in the way of this practice. Much effort should be directed at solving these issues in the most realistic way. This paper reviews potential actions by oncology specialists, and attempts to clarify the possible role of an academic society for oncology specialists in the development of cancer education systems at school.

    Although growing research focuses on breast cancer screenings, little is known about breast cancer prevention with risk reduction awareness for ethnic differences among college-age women. This study examined breast cancer prevention knowledge, beliefs, and information sources between non-Hispanic and Hispanic college women. Using a cross-sectional study, women at a university in the Southwest completed a 51-item survey about breast cancer risk factors, beliefs, and media and interpersonal information sources. The study was guided by McGuire's Input Output Persuasion Model. Of the 546 participants, non-Hispanic college women (n = 277) and Hispanic college women (n = 269) reported similar basic knowledge levels of modifiable breast cancer risk factors for alcohol consumption (52 %), obesity (72 %), childbearing after age 35 (63 %), and menopausal hormone therapy (68 %) using bivariate analyses. Most common information sources were Internet (75 %), magazines (69 %), provider (76 %) and friends (61 %). Least common sources were radio (44 %), newspapers (34 %), and mothers (36 %). Non-Hispanic college women with breast cancer family history were more likely to receive information from providers, friends, and mothers. Hispanic college women with a breast cancer family history were more likely to receive information from their mothers. Breast cancer prevention education for college women is needed to include risk reduction for modifiable health behavior changes as a new focus. Health professionals may target college women with more information sources including the Internet or apps.

    Full Text Available Purpose. The aim of this study was to determine: whether and at what stage of education is proper body posture learned, the intention of young adults to participate in activities teaching proper posture, and the effects of factors related with the said intention. Methods. The study involved 430 university students aged 18-24 years. Anthropometric data was collected. Participants completed questionnaires assessing physical activity level (IPAQ and their intention to participate in extracurricular activities teaching proper posture while sitting or walking, proper running technique, corrective gymnastics, or weight loss exercises. A self-assessment of posture, physical fitness, attractiveness, and body satisfaction was also completed. Results. Lower back pain was experienced by 41% of the respondents. Most were taught proper posture-related habits in primary school, followed by secondary school, and then at university. Many students expressed their intention to participate in the extracurricular activities. None of the questionnaire variables were associated with the intention to learn proper walking posture or proper running technique. The intention to participate in classes teaching proper sitting posture was associated with lower back pain in women and low physical activity level in men. In women, a relationship was found between the intention to participate in weight loss exercises and body dissatisfaction, high BMI, and poor self-evaluations of posture and attractiveness. In men, this activity was associated with body dissatisfaction. Conclusions. There is a need for further education on the development of proper postural habits at the university level.

    Full Text Available Background/Aim. Innovative marketing campaigns and promotional activities can successfully contribute to the improvement of public health by raising the level of general knowledge about health issues and benefits that the change of habits, eradication of undesirable behaviour and regular medical controls have. The focus should be on continuous marketing communication through various mass media or direct communication between medical staff and patients. The aim of this paper was to define the role that various communication channels have in the process of informing and educating the target group in case of breast and cervical cancer prevention. Methods. The survey based on polling a sample of 2,100 female patients of the Serbian Railways Medical Centre was conducted in the period October-December 2013. The questionnaire included questions about demographic characteristics, prevention habits of women, their level of information on that topic and communication channels they prefer. Results. There is a difference among respondents’ awareness level about preventive measures depending on demographic and geographical criteria. The results indicate the existence of variations in frequency of performing gynaecological examinations and Pap tests depending on different age, educational and residential groups. Although the largest percentage of women stated familiarity with the way of performing breast self-examination (78%, the majority of them had never per-formed mammography or ultrasonography (67%. The greatest number of women were informed about the possibility of preventing breast and cervical cancer by posters or brochures in health institutions (71% and mass media - television on the first place (74%, then specialized magazines about health (48%, radio (48%, web sites about health (42%, and daily newspapers (34%. The respondents consider the Ministry of Health and health institutions as the most responsible subjects for education of women about

    Despite the prevalence of testicular cancer among men 15-39 years of age, little has been done to increase awareness of this disease or educate males about its prevention. To fill this gap, the Standard Model of Health Communication was incorporated to design and implement a comprehensive testicular cancer campaign among male college students. To test the effectiveness of these messages, college students (N = 220) completed measures before and after the campaign. In addition, the authors obtained a control group of male college students (N = 52) who were not exposed to the messages. Survey items assessed awareness of testicular cancer and behaviors related to testicular cancer. Participants' knowledge of testicular cancer and likelihood of conducting a testicular self-exam increased significantly after being exposed to the campaign information. Men who were exposed to testicular cancer messages were more knowledgeable about testicular cancer and were more likely to conduct testicular self-examinations than were men in the control group.

    Rodriguez-Brenes, Ignacio A; Wodarz, Dominik

    2015-07-21

    Clonal evolutionary processes can drive pathogenesis in human diseases, with cancer being a prominent example. To prevent or treat cancer, mechanisms that can potentially interfere with clonal evolutionary processes need to be understood better. Mathematical modeling is an important research tool that plays an ever-increasing role in cancer research. This paper discusses how mathematical models can be useful to gain insights into mechanisms that can prevent disease initiation, help analyze treatment responses, and aid in the design of treatment strategies to combat the emergence of drug-resistant cells. The discussion will be done in the context of specific examples. Among defense mechanisms, we explore how replicative limits and cellular senescence induced by telomere shortening can influence the emergence and evolution of tumors. Among treatment approaches, we consider the targeted treatment of chronic lymphocytic leukemia (CLL) with tyrosine kinase inhibitors. We illustrate how basic evolutionary mathematical models have the potential to make patient-specific predictions about disease and treatment outcome, and argue that evolutionary models could become important clinical tools in the field of personalized medicine.
