Risk-Reducing Breast and Ovarian Surgery for Women at High Familial Risk
Preventive surgery is an option for selected people at very high inherited risk and requires careful, unhurried counselling.
The key things to know
- Risk reduction is substantial but not complete.
- Ovarian surgery affects fertility and menopause.
- Genetics, preferences, and alternatives guide the decision.
What surgery can and cannot do
Bilateral risk-reducing mastectomy removes most breast tissue to greatly lower the chance of breast cancer. It cannot remove every breast cell and does not reduce risk to zero. It is usually considered for a confirmed high-risk inherited variant or a particularly strong risk profile. It is not a routine response to anxiety or to a variant of uncertain significance alone.
The ovaries and fallopian tubes
Removal of both ovaries and fallopian tubes can reduce ovarian and related cancer risks in selected gene carriers. Its timing depends on the specific gene, age, family history, and childbearing plans. It is primarily an ovarian-risk decision; the size of any breast-risk reduction is uncertain. Before natural menopause, the operation causes permanent loss of fertility and surgical menopause.
Consider the whole person
Counselling should cover reconstruction or flat closure, altered sensation, scars, possible complications, body image, sexuality, fertility, and menopausal symptoms. Additional operations may be needed after reconstruction. Discuss recovery support, work, caregiving responsibilities, and costs. A second specialist opinion can help when choices are complex. The person having surgery should have time to understand and express their priorities.
Alternatives and follow-up
Enhanced breast screening and, in some situations, risk-reducing medication are alternatives or interim choices. Screening detects disease earlier but does not remove risk. After preventive surgery, follow-up remains necessary for symptoms, surgical outcomes, and other gene-associated risks. Do not assume that an operation on one organ removes the need to consider health risks elsewhere.
Take these questions to your appointment
- What is my estimated risk with and without surgery?
- How would surgery affect fertility, sensation, and future follow-up?
