Breast cancer is a significant health concern, accounting for a substantial proportion of cancer cases. Despite improvements in cancer survivorship, many women still require mastectomy as part of their therapeutic treatment. Mastectomy alone or delayed breast reconstruction (DBR) are two options available to women not suitable for immediate breast reconstruction at initial mastectomy. However, the presence of increased lateral adiposity (ILA) following mastectomy, commonly referred to as ``dog-ears,'' can lead to discomfort and aesthetic concerns. This paper explores the benefits and harms of ILA postmastectomy and its impact on patient satisfaction when choosing between mastectomy alone or DBR. A literature search was completed within OVID Medline, 1946-current, with the following terms, filtered for relevance: "mastectomy," "autologous reconstruction," "scar," "body image/dysmorphia," "patient-reported outcomes," "reconstructive surgical procedures/excess skin," "surgical flaps/dog ear." The disparity between clinical support and educational resources available for patients considering DBR options compared to those choosing mastectomy alone or pursuit of "living flat" is discussed. A common theme from qualitative research was the reported feeling of lack of inclusion in reconstruction planning by the patient. There were instances reported of residual skin remaining postmastectomy, against patient wishes. The findings emphasized the importance of shared decision-making and comprehensive preoperative education to ensure that patients are well-informed and satisfied with their chosen treatment approach. Further research is needed to address the specific needs and preferences of patients opting for mastectomy and to improve surgical techniques and education regarding living-flat options.
