What it measures
- CA-125 — Often elevated in ovarian cancer, but also in non-cancerous conditions like endometriosis.
- PSA (prostate-specific antigen) — A protein made by the prostate; high levels can indicate prostate cancer or benign enlargement.
- CEA (carcinoembryonic antigen) — Commonly used to monitor colorectal cancer and some other cancers.
- CA 19-9 — Often monitored in pancreatic cancer, though it can rise with other digestive issues.
- AFP (alpha-fetoprotein) — Used in liver cancer and some testicular cancers; also elevated in pregnancy.
- hCG (human chorionic gonadotropin) — A marker for certain testicular and gestational cancers; also high in normal pregnancy.
Preparation
No fasting is usually required. Tell your clinician about any recent illness, pregnancy, or medications, as these can affect marker levels.
Results and what they mean
Results are reported as a number with a reference range from the lab. A single result is rarely meaningful on its own; your clinician interprets trends over time along with your history, imaging, and other tests. This is general information, not medical advice.

Frequently asked questions
Can a tumor marker test tell me if I have cancer?
No. It can be elevated for many reasons, including benign conditions, and normal results do not rule out cancer. Diagnosis requires a biopsy or other tests.
Why does my doctor repeat this test?
Changes over time are more useful than one result. Your doctor may repeat it to see if treatment is working or if cancer has returned.
What if my marker level is high?
A high level does not always mean cancer. Your doctor will consider other causes and may order more tests to understand what it means for you.
Are these tests used for screening in healthy people?
Generally no. They are not reliable for early detection in people without symptoms or a known cancer diagnosis.
