[Breast reconstruction after mastectomy: necessity, evolution, techniques and research goals].

Breast reconstruction is recognized as an integrated part of breast cancer treatment today. Depending on tumor characteristics, different types of partial and total breast resections are indicated: tumorectomy, nipple/skin sparing or complete mastectomy. Patients' desires, general health status and body shape, as well as the necessity of adjuvant therapies, lead to the individual reconstruction plan. Next to implant-based reconstructions, autologous reconstructions play a great role, including local, pedicled and free flaps as well as autologous fat grafting. In cases of tumorectomy, oncoplastic surgery comes into play: it is the combination of a large tumor resection and immediate breast reconstruction with the remaining breast tissue.
