The role of radiologists in the era of oncoplasty.

New morphological and functional breast imaging techniques, progress in neoadjuvant treatments, and the development of new surgical techniques that include oncoplastic surgery, have made it possible to perform breast-conserving surgery in patients with large multifocal or multicentric breast tumours, where previously mastectomy would have been recommended. This allows for better aesthetic results, adequate oncological treatment, and improved quality of life. As a result, oncoplastic surgery has increased in local breast cancer treatment with radiologists playing a significant role in its planning through diagnosis and staging, and throughout the treatment process as they assess residual disease after neoadjuvant chemotherapy, mark the preoperative tumour volume and evaluate the correlation between the surgical specimen and presurgical imaging studies. The aim of this article is to present an update on the most relevant aspects of oncoplastic breast surgery and review the radiologist's role in surgical planning to optimise outcomes.
