The risk of breast cancer in relation to health habits and occupational exposures

BACKGROUND: Numerous studies have observed risk factors for breast cancer. We aimed to investigate and assess the relationship between individual, social, occupational and environmental determinants of breast cancer using a questionnaire among 100 newly diagnosed female breast cancer patients and 100 control female subjects without cancer.METHODS: A case-control study using a family ambulatory based survey was conducted among 200 female patients from all municipalities of Zenica - Doboj Canton. New cases of breast cancer among subjects of experimental group (n = 100) were diagnosed between January 1, 2003 and December 31, 2007 using the institutional clinical procedure for breast cancer diagnosis. Data were obtained using a self - rated questionnaire specially designed for this research. The questionnaire contains a group of questions about individual and demographic data, occupational and environment characteristics, reproductive hystory, body mass index, life style and quality life factors.RESULTS: Fifty two percent of our examinees with breast cancer are housewives. There were no significant differences between the two groups and their subgroups except for prevalence of routine physical activity (P = 0.016), unemployment (P = 0.004), history arrival menopause (P = 0.012), and type of occupation/ workplace (P = 0.015) among subjects with breast cancer in relation to control subjects. We found significantly higher prevalence for failure to routine physical activity (P = 0.006), obesity (P = 0.009), unemployment (P = 0.001), unsecure existence (P = 0.015), and low level of education (P = 0.001) in housewives in relationship to others occupation.CONCLUSION: The most common new cases of breast cancer were among housewife. Inverse significantly link between breast cancer and poverty, arrival time of menopause and distant-cousin- degree family history were found. For most women, physical activity may reduce the risk of invasive breast cancer

Background: Identifying risk factors of breast cancer is a key point for preventive strategies to reduce the incidence. The aim of current study was to determine most important risk factors for breast cancer in the Eastern Mediterranean Region (EMR) using a systematic review. Materials and Methods: PubMed, Scopus, Web of Science till August 24, 2012 and the reference lists of all included studies were searched. Analytic studies which had reported odds ratios (OR), relative risk (RR) or required data to calculate them were included. A total of 343 studies were critically appraised and finally 30 studies were meta-analyzed. Heterogeneity between the studies was assessed by I² and Cochran's Q. Egger's test was used to assess publication bias. Results: Twenty five casecontrol studies, one nested case-control and four cohort studies were included. The largest ORs were obtained for history of no live birth (2.25; 95%CI: 1.58-3.18), body mass index (BMI) more than 30 (2.21; 95%CI: 1.71-2.36), age at first pregnancy more than 30 years old (1.52; 95%CI: 1.30-1.77) and meat consumption more than three times per week (1.39; 95%CI: 1.03-1.87). The other important predictors were higher education and smoking as risk factors, physical activity and ovulatory stimulating medication as protective factors. Conclusions: The most important predictors of breast cancer in EMR were history of no live birth, BMI more than 30, age at first pregnancy more than 30 years old, physical inactivity and smoking. Almost all these risk factors are consistent with known risk factors for this cancer in other parts of the world.
