“…A study conducted in Turkey by Ceber et al (9) found no difference between the study and control groups in terms of the degree of stressor experienced in the last 5 years. On the other hand, similar to the results of the present study, it was reported that the self-reported stress in the last 5 years (15,22,23), having a stressful vital event in the last 2 years (24), and having stressful life events before the diagnosis (25) were associated with breast cancer.…”

Various studies that researched the relationship between breast cancer and abortus (15), and the use of oral contraceptives (10,14,15) reported that these factors could increase breast cancer risk. The multivariable analysis of the present study did not determine factors related to reproduction and obstetric history as independent risk factors.…”

“…The studies comparing the effect of social and economic status on the outcome focused mainly on the level of education and income. It was found in the literature that women who had higher education and income at the individual and social levels had a higher risk of breast cancer (15,30). Some studies examined the relationship between work stress and breast cancer, but no difference was found (31).…”

IntroductionCancer, a chronic and life-threatening disease, is an important cause of morbidity and mortality. The most common type of cancer diagnosed in women is breast cancer (1). Early recognition of high-risk women is important because of the development of surgical, medical, and oncologic alternatives for breast cancer, every passing year (2). Enlightening factors that contribute to breast cancer to prevent the disease, determine risk groups, and improve early diagnosis or treatment strategies are required.Even though the etiology of breast cancer was not clearly presented in the past, many epidemiologic risk factor studies have been conducted (3, 4), and many unchangeable and changeable risk factors (lifestyle and psychosocial factors) for breast cancer have been identified. According to some studies, changeable factors are useful for developing preventive strategies for breast cancer (5). However, researching stressful life events independently of factors such as coping style, behavioral pattern, and social support could be a flawed approach. A limited number of studies have examined the effects of these variables on the etiology of breast cancer (5, 6, 7). Socio-economic characteristics as risk factors for breast cancer are also discussed. An opinion suggested that socioeconomic characteristics could be an independent risk factor for breast cancer. Another aspect affecting life style such as reproduction and nutrition may be associated with risk of breast Eur J Breast Health 2017; 13: 206-12 DOI: 10.5152/ejbh.2017.3519 206 ABSTRACT Objective: The aim of this study was to determine the roles of biopsychosocial risk factors in the development of breast cancer. Materials and methods:This hospital-based case-control study included 491 women with breast cancer (study group) and 512 women who did not have cancer or other serious diseases (control group). Biological, psychological, and social risk factors were compared between the two groups. Data were collected using the semi-structured interview, the Stress Assessment Form, and the Coping Strategy Indicator to assess these factors. Results:When the significantly different biopsychosocial variables between the study and the control groups were evaluated together, independent breast cancer risk factors were found as follows: a stressor experienced in the last 5 years, age 40 years and older, inadequate social support perception, use of avoidance coping strategy, being a housewife, having a family history of cancer, and having a body mass index ≥25. Conclusion:This study showed a relationship between breast cancer risk and manageable variables (obesity, stressor and coping strategy, social support, and employment status), age and family history of cancer, which are biopsychosocial factors. Biopsychosocial aspects are becoming a greater part of many different healthcare systems.

“…The results of Hosseinzadeh et al (2014) in a case -control study demonstrated no association between high BMI and developing breast cancer (28). Low sample size, time of calculating of BMI, difference in diet and life style in area of research might be the causes of differences in results.…”

Background: Various studies in Iran on the role of BMI higher than normal (BMI ≥25) on breast cancer have reported different results.Objective: The aim of this systematic review and meta-analysis is to estimate the odds ratio of overweightness and obesity as risk factors of breast cancer in studies conducted in Iran.Evidence Acquisition: The following main databases were searched from 2004 to 2014 to find related articles: PubMed, Web of Science, Google Scholar, Scopus and Iranian databases (SID and Magiran), breast cancer conferences held in Iran, key journals, and the references of the selected articles. Keywords were: Cancer, Tumor, Neoplasm, Neoplasia, Carcinoma, Malignancy, Malignant, Benign. The combination with OR and added it to search field with AND to words such as Iran and breast was used as the search strategy. The observational studies (cohort, case-control, and cross-sectional) in Iran that had reported the relation between BMI and breast cancer in Persian and English were searched. There were no limitations in terms of age, race, ethnicity, and marital status for women. The exposure was BMI ≥ 25 (overweight and obese) and the outcome was breast cancer with pathological confirmation.Two reviewers separately used the STROBE checklist for quality assessment, critically appraised papers and extract the data. The overall estimate was the odds ratio. Results:Of 4396 studies, after evaluation of heterogeneity, 7 case-control studies with a sample size of 33552 were included in the meta-analysis. A significant relation was observed between obesity (OR = 1.81, 95% CI = 1.24 -2.64) and odds of breast cancer. A significant relation was also observed between overweightness and odds of breast cancer (OR = 1.46, 95% CI = 1.13 -1.89).Conclusions: Meta-analysis results showed a significant relation between obesity and overweight with risk of breast cancer in Iranian women. We recommended Iranian women to be aware of the effect of weight on breast cancer and encouraged them to decrease their weight via physical activity and diet control.
