Most of the approaches that were valid until recently in breast cancer surgery have undergone significant changes with rising awareness, increasing number of patients, and knowledge. It is important to repair the damage caused by surgical treatment performed in accordance with oncological principles and to obtain good cosmetic results. The quality-of-life indexes increase and body image is positively affected by the development of oncoplastic surgery and reconstruction techniques.The oncoplastic techniques are commonly used for the closure of glandular defects. Surgeons must pay attention to the breast volume, tumor location, the amount of breast tissue that would be removed, and the oncoplastic technique that may be required. Oncoplastic breast surgery allows wide local excision of the mass with good cosmetic results. In addition, a contralateral breast lift, breast augmentation or breast reduction may be required to accommodate the conceptually reconstructed breast. The use of oncoplastic breast surgery techniques results in lower mastectomy rates with equivalent local and long-term survival rates as compared with mastectomy and offers women the option of plastic and reconstructive interventions performed at the time of initial surgery. Mastectomy may be needed for large tumors, as breast-conserving surgery may not be possible or may not produce satisfactory cosmetic results. Breast reconstruction methods after mastectomy include autologous or implant-based breast reconstructions, which can be performed at the same time as the breast cancer surgery (immediate reconstruction) or at a later time (delayed reconstruction).Oncoplastic and reconstructive breast surgery minimizes the impact of breast cancer surgery and yields equivalent survival outcomes without psychological morbidity. With advanced techniques, better breast image than before can also be achieved. In this review, the technical details of oncoplastic breast surgery, surgical margin positivity management, reconstruction methods, radiation therapy given after reconstruction surgery, radiologic imaging modalities, and management of complications are discussed.
