Association between the type of child delivery and occurrence of breast cancer

Abstract

To explore the risk of breast cancer in relation to the type of child delivery we tested whether a type of delivery carries a high risk of breast cancer. This factor doesn't study earlier as we know. 1000 healthy women who were sent to one radiology center for general check-up or for initiating or continuing hormone-replacement therapy were selected. They were given a questionnaire about the type of prior child deliveries and also examined by an experienced physician to look for any signs of breast cancer. Screening mammography was performed in two standard views (craniocaudal and oblique mediolateral view). Among the mothers 19.39% had vaginal delivery and 80.61% had delivered by cesarean section. Among the women who had vagina delivery 93.6% had normal mammogram and 1.3% of them had malignancy and 3.2% had a benign breast nodule. P value for the association between the type of delivery and breast cancer was 0.617, which doesn't have any statistical significance. In this study, we concluded that the type of child delivery doesn't influence the risk of breast cancer in mothers. [Ahmadi S, Rahmani SH, Moghbel A, Navali N, Vazifekhah SH.
