Welcome to IBCCS

The International BRCA1/2 Carrier Cohort Study (IBCCS) is a collaborative study of women and men carrying a deleterious mutation in BRCA1 or BRCA2. The overall purpose of this study is to estimate prospectively the risks of breast, ovarian, and other cancers in BRCA1 and BRCA2 (BRCA1/2) carriers and to assess lifestyle and genetic factors that may modify cancer risks.
