Carcinoembryonic antigen (CEA) is primarily used as a tumor marker to monitor the response to treatment and detect recurrence in patients with colon cancer. CEA is occasionally elevated in patients with breast, lung, or ovarian cancer, but it is not typically used as a primary marker for these cancers. Prostate-specific antigen (PSA) is a tumor marker used for prostate cancer, and CA-125 is used for ovarian cancer. Carcinoembryonic antigen is mainly used to monitor colon cancer. While it can also be elevated in other cancers, such as breast and lung cancer, it is most commonly used to monitor colorectal cancer.
