How effective is risk-reducing mastectomy for a BRCA gene mutation?

The operation removes most breast tissue before cancer develops. It is different from surgery to treat a known tumour, and it does not remove the BRCA mutation or protect organs that can also be affected by inherited risk. Some people choose reconstruction during the same operation or later; others do not.

Recovery, sensation, body image, breastfeeding ability, wound healing, and reconstruction choices all deserve discussion. The operation has surgical risks, including infection, bleeding, fluid collection, changes in sensation, and a need for further procedures.

Meet a breast surgeon, genetics professional, and—if desired—a reconstructive surgeon. Review your exact genetic result, family history, breast imaging, alternatives such as surveillance or endocrine therapy, and the timing that fits your life.

Before surgery, ask about the incision, nipple-sparing eligibility, reconstruction materials, recovery at home, and how follow-up will work. Bring a support person to consultations if that helps you compare choices.

Before surgery, report a new breast or underarm lump, nipple discharge, skin dimpling, or a persistent change so it can be assessed. After surgery, contact the surgical team for fever, increasing redness, worsening pain, wound opening, heavy drainage, or sudden swelling; seek urgent help for severe breathing difficulty or chest pain.

How much risk reduction is expected for my specific mutation and history? What tissue will be removed, and what risk remains? Which reconstruction choices, sensation changes, complications, and recovery needs should I plan for?
