Breast surgery has evolved as a subspecialty of general surgery and requires a working knowledge of benign and malignant diseases, surgical techniques, shared decision-making with patients, collaboration with a multi-disciplinary team, and a basic foundation in surgical ethics. Ethics is defined as the practice of analyzing, evaluating, and promoting best conduct based upon available standards. As new information is obtained or as cultural values change, best conduct may be re-defined. In 2014, the Ethics Committee of the ASBrS acknowledged numerous ethical issues, specific to the practice of breast surgery. This independent review of ethical concerns was created by the Ethics Committee to provide a resource for ASBrS members as well as other surgeons who perform breast surgery. In this review, the professional, clinical, research and technology considerations that breast surgeons face are reviewed with guidelines for ethical physician behavior.
