Traditionally, bilateral mastectomy (BM) operations are performed by a single surgeon but a two‐attending co‐surgeon technique (CST) has been described. A questionnaire was sent to members of the American Society of Breast Surgeons to assess national BM practices and analyze utilization and perceived benefits of the CST. Among surgeons responding, most continue to use the single‐surgeon approach for BMs; however, 14.1% utilize the CST and up to 31% are interested in future CST use. Time savings, mentorship, cost savings, and opportunity to learn new techniques were identified as perceived CST advantages.
