Examples of tumor markers include prostate-specific antigen (PSA) for prostate cancer and cancer antigen 125 (CA 125) for ovarian cancer. Other examples include carcinoembryonic antigen (CEA) for colon cancer and alpha-fetoprotein for testicular cancer.
There are two main types of tumor markers: Circulating tumor markers. Tumor tissue markers. Circulating tumor markers are in: Blood. Urine (pee). Stool (poop). Bone marrow. Saliva (spit). To get a sample of your blood, a healthcare provider will run a blood test.
Healthcare providers categorize cancer blood tests into four main types: Complete blood count (CBC). A CBC can detect some blood or immune system cancers like leukemia and lymphoma. But it can’t detect solid organ cancers like lung, breast or colon cancers.
Tumor marker tests are commonly used by healthcare professionals to aid in cancer diagnosis, monitor the effectiveness of treatment, and detect the recurrence of cancer. When cancer cells develop in the body, they often release specific substances into the bloodstream.
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.
Here are some of the most common cancers we test for, and their respective markers: Bladder cancer: NMP-22; Breast cancer: CA 15-3/CA 27-29, HER2; Colorectal cancer: CEA, EGFR; Mesothelioma: SMR; Ovarian cancer: CA-125/HE4/ROMA; Pancreatic cancer: CA 19-9; Prostate cancer: PSA; Testicular cancer: AFP; Thyroid cancer: thyroglobin; Is there any ...
Most MCDs examine DNA that tumor cells release into blood. They may also analyze other biological molecules in blood, such as proteins. Tests that look at tumor markers in blood and other body fluids are sometimes called liquid biopsy tests.
Tumor markers may also be called cancer markers or biomarkers. A tumor marker is a substance found in the blood, urine, stool, the tumor itself, or tissue. The level of the tumor marker and which one it is can help you and your provider learn about your cancer.
These cancer biomarkers can be found in body tissue (via a biopsy), blood and urine. Some biomarkers are specific to one type of cancer, while others are related to several cancers. If your care team is planning to do a tumor marker test, this guide may help you learn more about the procedure.
These tests look for tumor markers, which are sometimes called cancer markers. Tumor markers are substances that are often made by cancer cells or by normal cells in response to cancer. For example, some tumor markers are proteins that certain cancer cells make in larger amounts than normal cells do.
