Objective: This study was conducted in order to determine the factors influencing breast cancer in women referred to health centers in Guilan province in 2015-2016.
Method: In a case- control study, 225 women with breast cancer were investigated. The control group consisted of225 healthy women of the relatives (third-rank) whose phone numbers were obtained from the patients. Data were collected through telephone interviews.
Results: The risk of breast cancer raised in women who have a family history of other cancers (OR= 3.5; 95% CI= 1.96-6.6) ,exposure to X-Ray (OR= 2.5; 95% CI=l.1-5.5), having more than 4 children (OR= 2.695% CI=l.2-4.8), age more than 36 years atfirstpregnancy(OR=2.3; 95% CI=0.7-5.1),primary levelofeducation (OR= 5.4;95% CI=2.8-11.2) and inadequate intake of fruit (OR=l.5; 95% CI=l-2.2). Also, presence of the following factors reduced breast cancer risk: regular menstruation (OR= 0.66; CI=0.4- 0.9), duration of breastfeeding more than 12 months, less than 6 months and 7-12 months (OR=0.23; 95% CI=0.09-0.59 , OR=0.29; 95% CI=0.17-0.49 and OR=0.03; 95% CI=0.01-0.08) and parity (OR=0.4; 95% CI=0.27-0.83) In multiple linear regression analysis of higher education (OR=0.16; 95% CI=0.03-0.77), using contraceptives for more than 16 years (OR=2.3; 95% CI=l .4-3.9), family history of other cancers (OR=6.1; 95% CI=l .9-19.3) and a history ofX-Ray exposure (OR=4.4; 95% CI=l.07-18.1) were considered as predictive factors. Conclusion: The results of this study emphasize the importance of informing women about breast cancer risk factors. So, identification of these risk factors is required as important means of prevention and treatment of breast cancer.
