[The role of the plastic surgeon in the management of breast cancer].

Plastic surgeons play a central role in the management of breast cancer, from prevention to post-treatment follow-up. Aesthetic breast surgery accounts for a significant proportion of plastic surgery in France. This practice places plastic surgeons in a privileged position for the early detection of breast cancer, enabling them to identify high-risk patients and steer them towards personalized monitoring. During multidisciplinary consultation meetings, the plastic surgeon's expertise guides the therapeutic strategy. By assessing the aesthetic and functional impact of treatments, he works with the surgical oncologist to define a surgical approach that respects oncological imperatives while limiting aesthetic and functional after-effects. Breast oncoplastic techniques have become an established part of conservative breast treatment, combining tumour removal and glandular remodelling. Breast reconstruction is an integral part of treatment, and must be systematically proposed in the event of mastectomy. Immediate reconstruction is discussed according to the histological characteristics of the cancer and the adjuvant treatments planned. During post-treatment follow-up, the plastic surgeon finalizes the breast reconstruction and manages the after-effects of conservative treatments through lipofilling or symmetrization procedures. This comprehensive approach makes the plastic surgeon a key player in modern breast oncology.
