- Abstract: Introduction: Breast cancer is the most common cancer and it is the second leading cause of cancer mortality for women after lung cancer in Iran. Given the high prevalence of breast cancer, it is of crucial importance to determine reproductive risk factors of breast cancer. Methods: A total of 139 female patients suffering from breast cancer (the case group) and 279 healthy females (the control group) who were age-matched participated in the study over the period from March 2018 to March 2019. Demographic and reproductive variables, including the number of pregnancies, breastfeeding, history of oral contraceptive use, abortion history, age at first menstruation and age at first childbirth, were all recorded via survey. Conditional Logistic regression was employed to calculate OR (CI: 95%). Results: The mean age of breast cancer patients was 50.8 ± 8.31. First degree family history of breast cancer, History of oral contraceptive use and delaying first pregnancy drastically increased the chance of breast cancer whereas breastfeeding and menstruation after the age of 14 reduced the chance of breast cancer. Conclusion: The findings of this study reveal that the age at first birth, use of oral contraceptives, first degree family history of breast cancer and lack of breastfeeding have a significant relationship with breast cancer. Thus, women who have experienced such factors are susceptible to breast cancer and need to be prioritized for preventive treatments and screening.
