Should healthy people get tumour markers like AFP tested? | CION Cancer Clinics
For most healthy people, a tumour marker test such as AFP is not worth doing. It misses many early liver cancers and raises false alarms in people who are well. Planned checks do help one group: people with cirrhosis and some hepatitis B carriers. This page explains who that is, why a marker alone misleads, and what a worried person should do instead. At CION Cancer Clinics, our team goes through your scan, blood test and biopsy reports with you and plans the next step.

The short answer
Should a healthy person get AFP or tumour markers checked?
For most healthy people, no. A tumour marker blood test is not a cancer test, and in a person with no symptoms and no liver disease it finds far more false alarms than real cancers. The exception is a small group of people whose liver is already at high risk, and for them the marker is only one half of a planned check.
What a tumour marker actually is
A tumour marker is a substance in the blood that some cancers make in larger amounts. AFP, short for alpha-fetoprotein, is the one linked to liver cancer. But healthy tissue makes these substances too. AFP rises with hepatitis flares, with a liver that is healing after injury and in pregnancy. Many liver cancers, especially small ones, never raise it at all.
Why this matters for a well person
When a test is run on someone with a very low chance of cancer, most abnormal results turn out to be something else. Each one still brings worry, repeat tests and sometimes scans and procedures that were never needed. Our page on why tumour markers are not a cancer test explains this in more detail.
A normal marker does not clear you, and a raised one does not diagnose you. That is true for everyone.Who it is for
Who does benefit from regular liver checks?
Liver cancer is one of the few cancers where planned checks in a high-risk group genuinely help. The group is defined by the liver, not by worry.
People with cirrhosis
Cirrhosis means long-term scarring of the liver, from any cause: hepatitis B or C, alcohol, fatty liver or something rarer. A scarred liver is the most common soil for liver cancer, so regular checks are usually advised.
Some hepatitis B carriers
Hepatitis B can lead to liver cancer even without cirrhosis. Whether a carrier needs regular checks depends on age, family history and how active the virus is. Your hepatologist or physician decides this.
Advanced scarring short of cirrhosis
People whose scan or biopsy shows heavy scarring, called advanced fibrosis, are sometimes included. The decision is made case by case.
Who is not on this list
A healthy adult with normal liver tests, a full-body package customer, or a relative who is simply anxious after a diagnosis in the family. For them, the first step is a doctor's assessment of liver risk, not a marker.
What to ask for instead
- A hepatitis B and C blood test, if never done
- Liver function tests and an ultrasound if your doctor advises
- Hepatitis B vaccination if you are not protected
Not sure whether this applies to you?
Ask an oncologistThe sensible route
What should I do instead of ordering a marker myself?
Find out your liver risk
Start with the questions that matter. Do you have hepatitis B or C? Has a scan ever shown fatty liver or scarring? Is there liver cancer or hepatitis B in close family? Our guide to who needs liver cancer screening walks through them.
See a doctor with the answers
A physician or hepatologist can tell you whether you belong in a surveillance group. Many people find they do not, and that answer is worth having on paper.
If you qualify, follow a plan
Surveillance means an ultrasound of the liver at regular intervals, often with AFP alongside, read by the same team each time. Our page on ultrasound plus AFP explains why the two go together.
If you do not, stop testing
Repeating markers every year in a low-risk person adds cost and worry without adding safety. Look after the liver itself: vaccination, weight, alcohol and blood sugar.
On the lab report
What the words on a marker report mean
- AFP
- Alpha-fetoprotein. A protein made by the liver of an unborn baby, and in small amounts by adults. Some liver cancers make much more of it.
- Reference range
- The span of values seen in most healthy adults at that laboratory. Being slightly outside it is common and often means nothing.
- False positive
- A raised result in someone who does not have cancer. This is the most frequent unusual result in healthy people.
- False negative
- A normal result in someone who does have cancer. Many small liver cancers produce little or no AFP.
- CEA, CA 19-9, CA-125
- Markers for other cancers, often bundled into health packages. None of them is a screening test for liver cancer.
- Surveillance
- Planned, repeated checks for a person already known to be at high risk. It is different from a one-off test done out of worry.

Commonly believed
Four beliefs about marker tests, and what is true
"A full cancer marker package will catch everything early."
No marker panel can screen a healthy person for cancer in general. Most early cancers do not raise markers, and many raised markers have nothing to do with cancer.
"My AFP is normal, so my liver is fine."
A normal AFP says nothing about fatty liver, hepatitis or scarring, and it can be normal even when a tumour is present. Liver health is judged from history, liver tests and imaging.
"My AFP is a little high, so I must have cancer."
Small rises are common in hepatitis, after liver injury and in pregnancy. Read our page on raised AFP without cancer, then take the report to a doctor rather than searching the number.
"Testing more often is always safer."
For a low-risk person, more testing mainly means more false alarms. For a high-risk person, what makes it safer is a regular, planned ultrasound, not extra markers.
Being straight with you
What this page cannot tell you
It cannot tell you whether you personally are in a high-risk group. That depends on your hepatitis status, your scans, your blood tests and your family history, and a doctor needs to put those together. It also cannot read a result you already have. The meaning of an AFP value depends on why it was done, what came before it and what the liver looks like on a scan.
Who this page does not apply to
If you already have cirrhosis, active hepatitis B, or a past liver cancer, this page is not about you. You should be on a regular plan, and AFP may well be part of it. If you were told to have surveillance and stopped, restart it rather than replacing it with occasional marker tests.
If you already have a raised result
Do not ignore it and do not panic. Repeat tests and a liver scan arranged by a doctor are the usual next step. CION arranges the scans through diagnostic partners, and the oncology team can review the result with you.

Common questions about testing tumour markers when well
Is AFP a good screening test for healthy people?
No. In people with no liver disease it misses many cancers and flags many people who are well. It has a place only in planned surveillance for people at high risk, usually beside an ultrasound. On its own, in a healthy person, it causes more worry than it prevents.
My health check package includes tumour markers. Should I skip them?
You can ask to leave them out. If they are done anyway, read any unusual value with a doctor rather than alone. Most slightly raised markers in a healthy person have an ordinary cause, and the right response is a measured review, not a chain of scans.
My father had liver cancer. Should I test my AFP?
First get tested for hepatitis B and C, because these often run in families through childhood spread. Then see a doctor about your own liver. If you carry hepatitis B or have liver scarring, a surveillance plan may suit you, and AFP may be part of it. If not, an AFP alone adds little.
Does fatty liver mean I need tumour markers?
Not on its own. Fatty liver without scarring carries a low liver cancer risk. What matters is whether scarring has developed. Your doctor may suggest a scan that measures liver stiffness. If cirrhosis is found, surveillance is then usually advised.
Can a blood test rule out liver cancer?
No single blood test can do that. Many liver cancers produce little or no AFP, especially when small. Imaging, read by an experienced radiologist, is the main way a liver tumour is found. A marker can add information, but it cannot give the all-clear.
What are the newer liver blood tests I have heard about?
Tests such as AFP-L3, DCP and combined scores are being studied, mainly for people already under surveillance. They are not meant for healthy people and are not widely available. Our page on AFP-L3 and DCP explains what is known.
How do I know if I am high risk?
The main signs are hepatitis B or C, cirrhosis from any cause, heavy long-term drinking, and liver cancer in close family alongside hepatitis B. If none of these apply and your liver tests are normal, your risk is low. A doctor can confirm this in one visit.
Can CION help me decide whether I need checks?
Yes. The oncology team can review your history and any reports you have, and tell you whether surveillance makes sense. Where it does, CION arranges ultrasound and blood tests through diagnostic partners and plans the follow-up. Call the helpline to start.
