Breast cancer after prophylactic mastectomy for Lobular Carcinoma-In-Situ (LCIS) - an unusual case.

Bilateral risk reducing mastectomy results in the greatest breast cancer risk reduction but is an irreversible intervention. Total mastectomy can never remove all breast tissue and there is always a small risk of breast cancer. Regular follow up and surveillance is beneficial. We present the case of a 47-year-old woman who presented with axillary lymph node metastatic breast cancer after risk reducing mastectomy in which only Lobular Carcinoma-in-Situ (LCIS) was present on histopathology.
