How high is worrying? What an AFP above 200 or 400 means | CION Cancer Clinics
An AFP in the hundreds makes liver cancer more likely and needs a prompt scan, but no single number proves cancer on its own. Hepatitis flares, cirrhosis, pregnancy and some other tumours can raise it too. This page explains where the figures 200 and 400 come from, how doctors read different levels, and what should happen in the days after a high result. 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
Is an AFP above 200 or 400 a sign of liver cancer?
The higher the AFP, the more likely a doctor is to suspect liver cancer, and values in the hundreds deserve a prompt scan. But no single number proves cancer on its own. Doctors diagnose liver cancer from a CT or MRI, and sometimes a biopsy, with the AFP read beside it.
Where the numbers 200 and 400 come from
You may have been told, or read, that an AFP above 400 means cancer. In older guidance, a level that high together with a liver mass was sometimes accepted as enough to diagnose hepatocellular carcinoma (HCC), the cancer that starts in the liver cells. Some doctors and studies use a figure around 200 as a point where suspicion rises sharply in someone with cirrhosis. Current guidelines lean on the scan pattern instead, because AFP can mislead in both directions.
Which cancer this page is about
This page is about primary liver cancer. If your report describes cancer that has spread to the liver from another organ, AFP is usually not the marker that matters. The page on primary and secondary liver cancer explains the difference.
More than one cause
What else can push AFP into the hundreds?
A high AFP has a short list of usual causes. Liver cancer is one of them, and it is not the only one.
Liver cancer
HCC is the cause doctors worry about first, particularly in someone with cirrhosis or long-standing hepatitis B. Very high values, in the thousands, point strongly in this direction, but still need a scan.
An active hepatitis flare
When hepatitis B or C inflames the liver, damaged cells regrow and can release AFP. Occasionally this reaches the hundreds, and it usually settles as the inflammation is controlled.
Cirrhosis itself
A scarred liver is constantly repairing itself, and that can keep AFP mildly raised for years. This is one reason the trend matters more than one reading.
Causes outside the liver
- Pregnancy, where a high AFP is expected
- Some testicular and ovarian germ cell tumours
- Hepatoblastoma, a liver cancer of young children

Ask an oncologistReading the level
How do doctors read different AFP levels?
What the report shows
How a doctor usually reads it
Just above your lab's normal range
Common with hepatitis or cirrhosis. Repeat it and check the scan.
Clearly raised, below 200
Needs a scan soon. Many causes are still possible.
Above 200 in someone with cirrhosis
Suspicion rises sharply. A triple-phase CT or MRI should not wait.
Above 400, or rising fast
Strongly suggests HCC, but a scan or biopsy still confirms it.
What happens next
My AFP is above 200. What should happen now?
See a doctor this week
Take the AFP report, any earlier AFP results and any recent scans to a medical oncologist or hepatologist. Do not wait for the next routine checkup.
A detailed scan
Usually a triple-phase CT or a contrast MRI, which shows how any spot in the liver takes up dye. CION arranges these through accredited diagnostic partners.
A repeat AFP and liver tests
A second AFP shows whether the level is climbing or settling. Liver function and hepatitis tests show whether a flare could explain it.
Team review
If a tumour is found, the tumour board looks at its size, your liver function and your fitness together before suggesting a plan. If nothing is found, closer follow-up continues, as explained on the page about rising AFP with normal scans.

Commonly believed
Four things people believe about a high AFP
"Above 400 means it is definitely cancer."
It makes cancer much more likely, especially with cirrhosis. It does not confirm it. Hepatitis flares and germ cell tumours can also produce high values, which is why a scan is always needed.
"A higher AFP tells you how long someone has."
AFP is one of many things doctors weigh. It cannot predict how any single person will do. Stage, liver function and response to treatment matter far more.
"If it is under 200, there is nothing to worry about."
Many liver cancers raise AFP only a little, or not at all. A modest level that keeps rising can matter more than one high reading.
"Liver tonics can bring the AFP down."
Lowering a number does not treat its cause. Some herbal products can harm a cirrhotic liver. Tell your doctor about anything you take, without fear of being judged.
Being straight with you
What this page cannot tell you
It cannot tell you whether your AFP means cancer. The same number can mean very different things in a person with an active hepatitis flare, in a person with long-standing cirrhosis, and in a person whose liver looked healthy last year. Only a doctor who sees your scans and your history together can weigh it.
AFP can also shape treatment choices
In people already diagnosed with HCC, a very high AFP is one of the things the team considers when planning. One later-line medicine, ramucirumab, was studied specifically in people whose AFP was above 400. Whether it is available to you in India, and whether it suits you, are questions for your oncologist. The page on targeted therapy for liver cancer covers the medicines.
Who this does not apply to
This page does not apply to pregnant women, to children, or to people being tested for testicular or ovarian tumours. Their AFP is read by different rules, and the doctor who ordered the test should explain it.
Questions we are asked
Common questions about high AFP levels
What is a normal AFP level?
Each laboratory prints its own normal range next to your result, and the ranges differ slightly between labs and units. Compare your value with the range on your own report, and compare repeat tests from the same lab where possible. The page on normal and raised AFP explains this further.
My AFP is in the thousands. Is that always cancer?
Values that high point strongly towards liver cancer or a germ cell tumour, and a scan is urgent. Very occasionally a severe hepatitis flare causes it. Either way, see a specialist within days, not weeks, and bring any earlier AFP results with you.
Can hepatitis B alone make AFP very high?
An active hepatitis B flare can raise AFP, and occasionally into the hundreds. It usually falls once the flare is controlled with antiviral medicine. Because hepatitis B also raises the risk of liver cancer, the scan is still needed to tell the two apart.
Should I repeat the AFP test before getting a scan?
No. If the level is clearly raised, arrange the scan and repeat the AFP alongside it. Waiting for a second blood test first only delays the test that actually answers the question.
The scan is clear but my AFP is still above 200. Now what?
Your doctor will usually look for other causes, such as a hepatitis flare, and may repeat the scan with a different method, often MRI. Closer follow-up continues until the AFP settles or a cause is found. A clear scan with a high AFP should not simply be filed away.
Does a falling AFP after treatment mean it is working?
In cancers that made AFP to begin with, a fall after treatment is usually a good sign, and a later rise can be an early warning. Scans still confirm what the number suggests. Your oncologist will tell you how your own results are being followed.
Can a liver detox or tonic lower my AFP?
No product treats the cause of a high AFP, and some herbal products can injure a scarred liver. If you are taking anything, write down the names and show the list to your doctor. They need to know, and they will not judge you for it.
Who should I see about a high AFP result?
A medical oncologist or hepatologist who can arrange the right scan and read it with your liver history. CION oncologists review AFP and scan reports and coordinate further tests through partner centres. Call the CION helpline to be directed to the right clinic.
