BRCA and Familial Breast Risk
Testing offers, surgical choices, and intensified screening
Pathogenic BRCA1/2 variants raise breast and ovarian cancer risk. In newly diagnosed breast cancer, age and clinical features guide when BRCA testing is offered; results can change surgery, systemic options, and family screening.
Key points

New breast cancer ≤65, triple-negative disease, male breast cancer, bilateral disease, strong family history, or a known family mutation are common triggers in current frameworks.
- Surgical decisionsTap for details · key note inside
Mastectomy versus breast conservation, contralateral risk-reducing choices, and ovarian-risk conversations are individualized — not a single mandatory operation.
