About the BCSC

The Breast Cancer Surveillance Consortium (BCSC) is a research resource for studies designed to assess the delivery and quality of breast cancer screening and related patient outcomes in the United States.

The BCSC is a collaborative network of seven mammography registries with linkages to tumor and/or pathology registries. The network is supported by a central Statistical Coordinating Center.

As of July 2011, the Consortium's database contains information on over 9.5 million mammograms (of which 7.2 million were screening mammographic examinations), 114,000 breast cancer cases (95,000 invasive and 19,000 ductal carcinoma in situ), and over 2.3 million women.

A full description of the history and early work of the BCSC can be found in Breast Cancer Surveillance Consortium: Evaluating Screening Performance in Practice.
