Women at high risk of breast/ovarian cancer can be approached to be part of a number of national studies. The studies overlap with the EMBRACE study protocol, in the sense that some patients are eligible to participate in more than one study. For the subjects who have enrolled in other studies, and have already completed a lifestyle questionnaire, consent can be obtained to transfer that data to the EMBRACE study, and vice versa.
A cohort of gene carriers generated by EMBRACE is included in the International BRCA Carrier Cohort Study (IBCCS) in order to perform analyses on lifestyle risk factors. EMBRACE data also included in the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA) for the analyses on cancer risk in BRCA1 and BRCA2 mutation carriers.
