Risk Factors Dataset

The BCSC Risk Factors Dataset was updated March 2020


This risk factors dataset may be useful to people interested in exploring the distribution of breast cancer risk factors in US women. The dataset includes information from 6,788,436 mammograms in the BCSC between January 2005 and December 2017. The dataset includes participant characteristics previously shown to be associated with breast cancer risk including age, race/ethnicity, family history of breast cancer, age at menarche, age at first birth, breast density, use of hormone replacement therapy, menopausal status, body mass index, history of biopsy, and history of breast cancer. These data can be used to describe the distribution of breast cancer risk in the general population or to explore relationships among breast cancer risk factors. See the Risk Factors Dataset Documentation for more information about the variables in the dataset.
