Rates of contralateral prophylactic mastectomy (CPM) have doubled over the last decade among women considered low risk for developing contralateral breast cancer. Despite the strong association between CPM and breast reconstruction, little is known about the clinical encounter between patients and plastic surgeons. A qualitative study was performed to understand how plastic surgeons describe their roles in the treatment decision-making process through their consultations with women who have unilateral early-stage breast cancer. Semi-structured interviews with Ontario plastic surgeons were conducted. An inductive and interpretive thematic approach was initially used to analyze the data. The four principles of biomedical ethics then served as the conceptual lens to interpret the findings. The participants in this study were 18 plastic surgeons, and data saturation was reached. Four themes were identified: maintaining non-maleficence, supporting patient autonomy, delivering (un)equal health care, and providing care to enhance well-being. The ongoing push-pull between competing ethical principles was the overarching theme, specifically, striving to balance parallel responsibilities to do no harm while also respecting patients' rights to make their own healthcare decisions. In this patient-centric climate, it is important to acknowledge that patients may value outcomes such as achieving greater peace of mind above other clinical factors and are willing to incur additional risks to achieve these goals. Shared decision-making will help to reveal the rationale underlying each individual's treatment choice, which in turn will allow physicians to appropriately weigh patient requests with the best available medical evidence when counseling women on decision-making for breast cancer care.
