[Realizing systematic cavity margins in conservative breast cancer surgery].

Abstract

The quality of surgical margins in lumpectomy are strong criteria to define risk of locoregional recurrence when conservative treatment is undertaken. Intraoperatively, the limits of adequate resection are sometimes difficult to define. This is why some teams propose the realization of systematic cavity margins during the excision of lumpectomy during the same operation. We expose the potential benefits of this type of practice using data from the literature.
