About Breast CFR
Overview
The Breast CFR includes lifestyle, medical history, and family history data collected from more than 55,000 women and men from 14,000 families with and without breast cancer. The Breast CFR began recruiting families in 1996, and all participants are followed up 10 years after recruitment to update personal and family histories and expand recruitment if new cases have occurred since baseline.
