Contralateral Prophylactic Mastectomy Consensus Statement from the American Society of Breast Surgeons: Additional Considerations and a Framework for Shared Decision Making

The American Society of Breast Surgeons (ASBrS) encourages an evidence-based and patient value focused approach to contralateral prophylactic mastectomy (CPM). The ASBrS convened a panel of experts to develop a consensus statement on CPM.1 The majority of women will obtain no oncologic benefit from CPM, and therefore CPM should be discouraged in average-risk women with unilateral breast cancer. Consideration of the patient’s preferences and values and an informed discussion of the risks and benefits of CPM is recommended for all patients pursuing mastectomy, along with a direct recommendation by the surgeon for or against CPM.
