A tumor marker is anything present in or produced by cancer cells or other cells of the body in response to cancer or certain benign (noncancerous) conditions that provides information about a cancer, such as how aggressive it is, whether it can be treated with a targeted therapy, or whether it is responding to treatment. See the Tumor Markers page for more information.

Listed below are tumor marker tests that are in common use, mainly to determine treatment or to help make a diagnosis of cancer. This list is not comprehensive; in particular, new tumor markers frequently become available and may not be included.

This list also does not include the many tumor markers that are tested by immunophenotyping and immunohistochemistry to help diagnose cancer and to distinguish between different types of cancer.

Some tumor markers listed below are targets for targeted therapy in multiple cancers but serve as tumor markers for only a subset of cancers. For each test, the main cancer types that it is used for are listed. Some markers may be used for other cancer types that are not listed.
