Mammography Data from Breast Cancer Surveillance Consortium

$0 / year

This dataset includes data from a random sample of 20,000 digital and 20,000 film-screen mammograms received by women age 60-89 years within the Breast Cancer Surveillance Consortium (BCSC) between January 2005 and December 2008. Some women contribute multiple examinations to the dataset. Data is useful in teaching about data analysis, epidemiological study designs, or statistical methods for binary outcomes or correlated data.

Categories: ,

This dataset includes the mammography assessment and subsequent breast cancer diagnosis within one year as well as participant characteristics that have been previously shown to be associated with mammography performance including age, family history of breast cancer, breast density, use of hormone replacement therapy, BMI, 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.
