Learn moreLCIS - Lobular Carcinoma In Situ
Lobular carcinoma in situ, or LCIS, is generally considered to be a pre-cancerous condition. It is lobular because the cancer is confined to the lobules—which are the glands that actually make milk. Carcinoma refers to any cancer that begins in the skin or other tissues that cover internal organs—such as breast tissue. In situ or "in its original place" means that the cancer has not spread to any surrounding tissues.
