Identification and Recruitment of Subjects. Participants will be recruited via the Lombardi Comprehensive Cancer Center's Familial Cancer Registry and the Non-therapeutic Subject Registry Shared Resource. These registries contain over 800 female BRCA1/2 positive participants. In addition, the investigators will recontact participants from prior trials who have consented to be recontacted for future research. Female index cases will be identified based on vital status, recency of contact, and availability of test reports documenting their positive BRCA1/2 status. Where available, pedigrees will also be reviewed.
