Long-term oncological outcomes after nipple-sparing mastectomy and implant-based immediate breast reconstruction in a population-based cohort of breast cancer patients

Background

Nipple-sparing mastectomy (NSM) offers superior cosmetic and patient-reported outcomes compared with skin-sparing mastectomy (SSM), although its oncological safety remains debated. This study evaluated recurrence and survival after NSM versus SSM in women with breast cancer receiving implant-based immediate breast reconstruction (IBR).
