Alternative definition : NCI-GLOSS: There are 2 types of stage 0 breast carcinoma in situ: 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 in the breast. In some cases, DCIS may become invasive cancer and spread to
other tissues, although it is not known 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 with making milk) of the breast. This condition seldom
becomes invasive cancer; however, having LCIS in one breast increases the risk of
developing breast cancer in either breast.;
