Association between lifestyle menstrual/reproductive history and histological factors and risk of breast cancer in women biopsied for benign breast disease

摘要

PurposeWomen with benign breast disease (BBD) have an increased risk of subsequent breast cancer. However, whether conventional breast cancer risk factors influence risk of breast cancer among women with BBD is unclear. In this study, we investigated the associations of lifestyle, menstrual/reproductive, and histological factors with risk of breast cancer among women biopsied for BBD.
