Carcinoma of the breast (breast cancer) in situ stage 0. Definition

Medical Definition: Carcinoma of the breast (breast cancer) in situ stage 0

There are two types of breast carcinoma (breast) in situ Stage 0: Ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS). DCIS is a noninvasive condition in which abnormal cells are found in the lining of a breast duct (a tube that carries milk to the nipple). The abnormal cells have not spread outside the duct to other tissues of the breast. In some cases, DCIS may spread to other tissues, but do not know how to predict which lesions will become invasive cancer. LCIS ??is a condition in which abnormal cells are found in the lobules (small sections of tissue involved in the production of milk) in the breast. This condition seldom becomes invasive cancer, but having LCIS in one breast increases the risk of breast cancer either. Also called breast carcinoma (breast) in situ.
