The term "oncoplastic surgery" stands for surgical procedures that allow the safe removal of tumor tissue and the creation of an esthetic breast appearance despite very large tumors or tumors with an unfavourable localization. Together with preoperative systemic therapy, this technique allows the preservation of the breast even in large and extensive tumors in most cases. If, however, because of tumor extent or localization, breast conserving surgery is not feasible, I also offer breast reconstruction with silicone-based implants.
