Overview
This digital mammography dataset includes data derived from a random sample of 20,000 digital and 20,000 film-screen mammograms performed between January 2005 and December 2008 from women in the Breast Cancer Surveillance Consortium. This dataset does not include images. Some women contribute multiple examinations to the data. The dataset may be useful to people interested in teaching data analysis, epidemiological study design, or statistical methods for binary outcomes or correlated data. The dataset includes the mammogram assessment, subsequent breast cancer diagnosis within one year, and participant characteristics previously shown to be associated with mammography performance including age, family history of breast cancer, breast density, use of hormone therapy, body mass index, history of biopsy, receipt of prior mammography, and presence of comparison films.
These data are recommended for use as a teaching tool only; they should not be used to conduct primary research. View an example biostatistics data analysis exam question based on these data.
