Risk-reducing mastectomy for women with no personal history of breast cancer
- bilateral risk-reducing mastectomy is appropriate only for a small proportion of women who are from high-risk families and should be managed by a multidisciplinary team
- bilateral mastectomy should be raised as a risk-reducing strategy option with all women at high risk
- women considering bilateral risk-reducing mastectomy should have genetic counselling in a specialist cancer genetic clinic before a decision is made
- discuss the risks and benefits of risk reducing mastectomy with women with a known or suspected BRCA1, BRCA2, or TP53 mutation
- offer women who have BRCA1, BRCA2 or TP53 mutations but who decide against risk-reducing mastectomy, surveillance according to their level of risk
- pre-operative counselling about psychosocial and sexual consequences of bilateral risk-reducing mastectomy should be undertaken
- the possibility of breast cancer being diagnosed histologically following a riskreducing mastectomy should be discussed pre-operatively
- all women considering bilateral risk-reducing mastectomy should be able to discuss their breast reconstruction options (immediate and delayed) with a member of a surgical team with specialist oncoplastic or breast reconstructive skills
- a surgical team with specialist oncoplastic/breast reconstructive skills should carry out risk-reducing mastectomy and/or reconstruction
- women considering bilateral risk-reducing mastectomy should be offered access to support groups and/or women who have undergone the procedure
