Quick answer
Cancer and tumor marker tests are laboratory tests that measure proteins, hormones, or other substances associated with particular cancers. Some markers are used to help monitor a known cancer over time, while others support an evaluation when symptoms or imaging point to a concern. No tumor marker is a perfect screening test, and results are always interpreted with other findings.
What this test measures
Tumor markers are substances that the body or a tumor may produce in larger amounts when certain cancers are present. They can be detected in blood, urine, or tissue. Examples include CA-125 for ovarian cancer, CEA for colorectal and other cancers, and PSA for prostate cancer. Each marker has its own typical uses and limitations.
These tests are most often used to monitor a cancer that has already been diagnosed, to see how well treatment is working, or to watch for recurrence after treatment. Some markers also help support an initial evaluation when combined with imaging and biopsy. The sample is usually blood, though urine and other specimens are used for specific markers.
Tumor markers can rise for reasons other than cancer, and not every cancer produces a detectable marker. That is why a single elevated result does not diagnose cancer and a normal result does not rule it out. A qualified healthcare provider selects the appropriate markers and interprets them together with the complete clinical picture.
