Family study aims to unlock secrets of hereditary breast and ovarian cancer

This completed study enrolled 377 individuals and families with a high risk of breast or ovarian cancer due to known or suspected genetic factors. Researchers collected medical records, questionnaires, and biological samples to better understand the disease's natural history and genetic causes. No treatment was provided, but participants received genetic counseling and referrals if needed. The goal was to create a resource for future research into cancer prevention and early detection.
