The Breast Cancer Surveillance Consortium (BCSC) has extended its version 2 invasive breast cancer risk model to include body mass index (BMI), second-degree family history of breast cancer, and age at first live birth. The new version 3 model estimates a woman’s five- and ten-year risk of developing invasive breast cancer based on her age, race and ethnicity, first- and second-degree family history, breast density, history of benign breast biopsy, BMI, and age at first live birth.
