The short answer
Beta-hCG (beta-human chorionic gonadotropin) is a hormone found in blood and urine during pregnancy. It is also used as a tumor marker for germ cell tumors and choriocarcinoma. Care teams use it to help assess stage, prognosis, and response to treatment. Pregnancy and other noncancer conditions can also raise it.
Beta-hCG is a hormone normally found during pregnancy.
It is also used as a tumor marker, mainly with germ cell tumors and choriocarcinoma.
It can be measured in blood or urine.
Pregnancy and some other conditions raise hCG, so it is always read in context.

The short version
hCG stands for human chorionic gonadotropin. Cancer care usually refers to beta-hCG. It is a hormone found in blood and urine during pregnancy. It can also be higher than normal in some cancers, so it is used as a tumor marker. It is not a simple yes-or-no cancer test.
What beta-hCG is used for in cancer care
The National Cancer Institute lists beta-hCG as a marker for choriocarcinoma and germ cell tumors (tumors that start in the cells that become eggs or sperm). It can be measured in blood or urine. The National Cancer Institute says it is used to assess stage, prognosis, and response to treatment:
- Stage: how far the cancer has spread.
- Prognosis: the likely course of the disease.
- Response: how well treatment is working.
Why it is not read alone
The National Cancer Institute notes two limits that apply to tumor markers in general. Noncancerous conditions can sometimes raise a marker. And not everyone with a given cancer has a higher level of its marker. So one number is easy to misread. Care teams read it together with imaging, exams, and other results. When a marker is checked again and again during treatment, the pattern over time can help show whether treatment is working.
For hCG in particular, pregnancy raises it, so your team reads the number with that in mind.
Normal ranges vary by lab
Your report lists a reference range, the range that lab calls normal. MedlinePlus explains that labs often use different testing methods, so they often use different reference ranges. Results from different labs can't be compared directly, and using the same lab helps when tracking trends. Your care team knows which lab ran your test and how to read your result.
What to ask
Ask why your care team is measuring hCG. Ask what your level and its trend suggest, and how the result fits with your other markers and scans. Their reading of your full picture is what applies to you.

Common questions
Does a high hCG mean I have cancer?
Not by itself. hCG is normally found during pregnancy, and the National Cancer Institute notes that noncancerous conditions can sometimes raise a tumor marker. Your care team reads it with your other results.
Which cancers is beta-hCG used for?
The National Cancer Institute lists beta-hCG as a marker for choriocarcinoma and germ cell tumors. It can be measured in urine or blood.
How is beta-hCG used in cancer care?
The National Cancer Institute says it can help assess stage, prognosis (the likely course of the disease), and response to treatment. The pattern across repeated tests helps your care team.
Is this the same hormone a pregnancy test looks for?
Yes, hCG is the hormone found during pregnancy. In cancer care, the result is read differently and alongside other tests. Ask your care team what they are looking for in your case.

Review details and limits
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes, and this is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and then compared with the sources listed on it, looking for statements those sources do not back up. That check is not a sentence-by-sentence record and can miss errors. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
