Digital Mammography Example Dataset


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 BCSC between January 2005 and December 2008. Some women contribute multiple examinations to the dataset. It may be useful to people interested in teaching about data analysis, epidemiological study designs, or statistical methods for binary outcomes or correlated data. 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. See the Digital Mammography Example Dataset Documentation for more information about the variables included in the dataset.

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.

Investigators interested in conducting analyses of digital mammography performance can submit a proposal in order to request a more complete sample of digital and film-screen mammograms conducted within the BCSC (see Submitting a Proposal & Working with the BCSC).
