Commentary on the Consensus Statement of the American Society of Breast Surgeons on Contralateral Prophylactic Mastectomy.

The increasing rate of contralateral prophylactic mastectomy (CPM) led the American Society of Breast Surgeons (ASBrS) to issue an evidence-based consensus statement on CPM, as well as a discussion guide that health care providers can use to facilitate shared decision making with patients considering CPM for unilateral breast cancer. This article suggests several ways to improve the discussion guide by eliciting patient values and preferences and by providing more current, detailed, and balanced information about the potential risks and benefits of CPM.
