Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
