<unk> , for Carcinoma Antigen 15-3, is a tumor marker for many types of cancer, most notably breast cancer. It is derived from MUC1.<unk>  and associated CA 27-29 are different epitopes on the same protein antigen product of the breast cancer-associated MUC1 gene. Elevated<unk> , in conjunction with alkaline phosphatase (ALP), was found to be associated with an increased chance of early recurrence in breast cancer. Both<unk>  and CA 27-29 may be elevated in patients with benign ovarian cysts, benign breast disease, and benign liver disease. Elevations may also be seen in cirrhosis, sarcoidosis and lupus.
