Hereditary Cancers — 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.

Figure summary
This educational figure shows: BRCA.
Key points
Who is offered testing?
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.
- Key note inside
Surgical decisions
Mastectomy versus breast conservation, contralateral risk-reducing choices, and ovarian-risk conversations are individualized — not a single mandatory operation.
Surveillance
High-risk pathways often combine yearly mammography with breast MRI. Start age depends on counseling and the earliest family diagnosis.

Frequently asked questions
Is BRCA testing automatic for everyone?
No. Offers follow guideline frameworks (for example many patients ≤65) and clinical features.
Does BRCA force mastectomy?
No. Breast-conserving surgery may still be appropriate; risk-reducing options are discussed separately.
