Tumor marker tests measure the levels of certain substances, known as tumor markers, in the blood, urine, or tissues of some patients with cancer. While these tests can provide valuable information about the presence, extent, or response to treatment of a cancer, they are typically not definitive on their own. This is because tumor markers can be elevated in conditions other than cancer, and not all cancers produce detectable levels of these markers. Therefore, tumor marker tests are often used in conjunction with other diagnostic tests to diagnose and monitor cancer.
