Does Risk-Reducing Mastectomy Treat a BRCA Gene Mutation?

BRCA1 and BRCA2 mutations are inherited changes that can increase the likelihood of certain cancers. Surgery changes the amount of breast tissue at risk; it does not alter the genetic change in the body's cells. Some breast tissue can remain after surgery, so the risk is reduced rather than removed entirely.

This operation is also different from treatment for breast cancer that has already been diagnosed. If cancer is present, the care plan may include other treatments based on the cancer's type and stage. A BRCA mutation can also affect cancer risk in organs beyond the breast, so breast surgery does not address every risk linked with the mutation.

Discuss the decision with a breast surgeon and a genetics professional. They can review your confirmed genetic result, personal and family history, breast screening options, reconstruction choices, and the possible effects on sensation and appearance. If surgery is not chosen, ask for a personalised surveillance plan and confirm which appointments or imaging tests are recommended.

Before consenting, ask how much breast tissue is expected to be removed, whether nipple-sparing surgery is suitable, how reconstruction would be staged, and what symptoms should prompt a call after the operation. Bring your genetic report if it is available.

Seek prompt medical advice for a new breast or underarm lump, a change in breast shape, skin dimpling, nipple inversion, unusual nipple discharge, or persistent localised pain. These signs can have causes other than cancer, but they need clinical assessment, especially when you carry a BRCA mutation.

After surgery, contact your surgical team urgently for heavy bleeding, rapidly increasing swelling, worsening redness, fever, severe pain, or shortness of breath. Follow the discharge instructions supplied by your team because recovery advice depends on the operation and reconstruction used.

Ask: What does my BRCA result mean for my breast and other cancer risks? What are the benefits and limitations of surgery for me? Which screening plan applies if I delay or decline surgery? What reconstruction options fit my health and preferences? Who will coordinate my genetics, breast, and follow-up care?
