Brief Summary

The Breast Cancer Surveillance Consortium (BCSC) database contains data from 1994-2009 on breast cancer screening, quality, and outcomes, and its main goal is to advance breast cancer research. This project is funded to maintain the BCSC database and share the data with investigators. Our objectives are to:

• Maintain the BCSC pooled database using secure methods that protect the confidentiality of women, radiologists, facilities, and BCSC registries;
• Encourage and facilitate sharing of BCSC research resources, and continue developing and implementing our communications plan to expand resource dissemination;
• Provide statistical and scientific expertise to researchers, distribute customized limited datasets, and analyze BCSC data;
• Develop and support a new web-based dynamic query tool and other electronic interfaces to efficiently share aggregated BCSC data with the public.

Study Population

The BCSC pooled database includes data from seven BCSC registries, of which five are currently active. Information comes from a large study population that is ethnically, geographically, and socioeconomically diverse. The database currently includes 9 million mammograms from 2.3 million women interpreted by over 1400 radiologists at 400 facilities. There are 1.1 million digital mammograms; 660,000 ultrasounds; 180,000 benign and malignant biopsies; and records of over 155,000 deaths. Over 107,000 women have a breast cancer diagnosis, of which 83% are first diagnosed in 1994 or later. The data are collected in the course of routine, clinical care to accurately represent community practice.
