How is liver cancer diagnosed, and which tests will I need? | CION Cancer Clinics
Liver cancer is diagnosed with a contrast CT or MRI of the liver, blood tests including AFP, and sometimes a biopsy. In people with cirrhosis or long-term hepatitis B, a typical scan pattern is often enough to confirm it without a needle. This page explains each test, what it can and cannot answer, why a biopsy is not always needed, and how the results come together into a plan. 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
How do doctors find out whether a liver spot is cancer?
Liver cancer is diagnosed with a special contrast scan of the liver, blood tests, and sometimes a biopsy. In a person who already has cirrhosis or long-standing hepatitis B, the scan alone is often enough to make the diagnosis, without a needle.
Which liver cancer this page is about
This page is about primary liver cancer, which starts in the liver itself. The commonest type is hepatocellular carcinoma, usually shortened to HCC. Many people who search for liver cancer after a scan actually have cancer that started somewhere else, such as the bowel or the breast, and spread to the liver. That is diagnosed differently, usually by finding the original cancer. If that sounds like your situation, read the two very different things called liver cancer first.
Why HCC is unusual
For almost every other cancer, a doctor needs a piece of tissue under a microscope before calling it cancer. HCC is the main exception. In a liver that is already scarred, a tumour of this kind lights up and fades on a contrast scan in a pattern so typical that international guidelines accept the scan as proof. A biopsy is still used whenever that pattern is missing or the liver is otherwise healthy.
The tests, one by one
Which tests are used, and what does each one answer?
No single test does the whole job. Each one answers a different question, and the team reads them together.
Ultrasound
Usually the first picture. It is quick, safe and good at spotting that something is there. It cannot reliably say what the spot is, so a suspicious ultrasound leads to a contrast scan rather than a diagnosis.
Triple-phase CT or contrast MRI
The test that actually decides. Pictures are taken at different moments after a contrast injection to see how blood flows in and out of the spot. Read more about the triple-phase CT.
A plain CT without contrast cannot make this diagnosis.Blood tests
AFP is a protein that HCC sometimes releases. It supports the picture but never proves or rules out cancer on its own. Liver function tests, clotting, platelets and kidney tests show how well the liver is coping, which matters as much as the tumour itself.
Usually also checked
- Hepatitis B and C
- Bilirubin, albumin and INR
- A full blood count
Biopsy
A thin needle takes a small core of tissue. It is used when the scan is not typical, when the liver has no cirrhosis, or when another kind of cancer is suspected. How it is done is explained on liver biopsy: what to expect on the day.
Not sure whether this applies to you?
Ask an oncologistFrom spot to plan
What happens between the first scan and a diagnosis?
Something is noticed
A spot on a routine ultrasound, a rising AFP during surveillance for cirrhosis, or symptoms such as weight loss or yellow eyes. Your doctor asks about hepatitis, alcohol, diabetes and fatty liver, without judgement.
The contrast scan
CION arranges a triple-phase CT or a contrast MRI through its diagnostic partners. A radiologist grades the spot on a scale called LI-RADS.
Blood tests alongside
AFP and the liver function panel are taken at about the same time, so the scan and the bloods can be read together.
Biopsy only if needed
If the scan is clear-cut in a cirrhotic liver, the team may go straight to planning. If not, a biopsy is arranged through a partner hospital.
The tumour board
Oncologists, surgeons and radiologists review the scans, the bloods and the state of the liver together, and agree the stage and the options.
On your report
What do the words on a liver scan report mean?
- Lesion or SOL
- Any spot that looks different from the liver around it. SOL means space-occupying lesion. Neither word means cancer.
- Arterial enhancement
- The spot lights up brightly in the early pictures, because it is fed by arteries. HCC usually does this.
- Washout
- In the later pictures the spot turns darker than the liver around it. Brightening early and fading late together is the classic HCC pattern.
- LI-RADS
- A grading scale radiologists use in people at high risk. LR-1 means certainly harmless, LR-5 means definitely HCC, and the grades between carry rising levels of concern. Our LI-RADS page goes through each one.
- Cirrhosis
- Long-term scarring of the liver. It raises the risk of HCC and also decides how much treatment the liver can take.
- AFP
- Alpha-fetoprotein, a blood protein that can rise with HCC, and also with hepatitis flares and pregnancy.

One field. No form to fill in, and no charge for the call.
Did you know
A diagnosis made on a scan alone only counts in people at high risk, mainly those with cirrhosis or chronic hepatitis B. In a liver that is otherwise healthy, the same picture can belong to several harmless conditions, so a biopsy is usually needed before anyone says cancer.
Commonly believed
What do families often get wrong about liver cancer tests?
"Without a biopsy, the doctors cannot be sure."
In a cirrhotic liver, a typical contrast scan is as reliable as a biopsy and avoids the needle. Insisting on one can delay treatment without adding certainty. Read why HCC can be diagnosed without a biopsy.
"The AFP is normal, so it cannot be cancer."
Many people with HCC have a normal AFP, especially when the tumour is small. The scan carries more weight than the blood test.
"A PET scan will settle it."
Many liver cancers do not show up well on a standard PET scan. A normal PET does not rule HCC out, which is why the contrast CT or MRI comes first.
"Once it is diagnosed, the tests are over."
The diagnosis is only half the picture. Tests of how well the liver works decide which treatments are safe, so expect more blood tests and possibly an endoscopy before a plan is agreed.
Being straight with you
What can this page not tell you?
It cannot tell you whether the spot on your scan is cancer. That depends on the exact pictures, how they were taken, the state of your liver and your blood results, read together by people who can see them. Two reports with similar wording can mean quite different things.
Who this does not apply to
The scan-only route does not apply to people without cirrhosis or long-term hepatitis B, to cancer that spread to the liver from elsewhere, or to bile duct cancer inside the liver, which nearly always needs a biopsy. Children with liver tumours follow a separate path, explained on the hepatoblastoma page.
What to do with the report you have
Keep the original scan images, not just the printed report. A second reading of the actual pictures is often more useful than a new scan. CION's tumour board can review scans done elsewhere and tell you whether anything more is needed.
If you are unsure what your report means, call the helpline and have it ready. Someone will explain the next step.Questions we are asked
Common questions about diagnosing liver cancer
Can ultrasound alone diagnose liver cancer?
No. Ultrasound is good at noticing that a spot is there, and it is the usual surveillance test for people with cirrhosis. It cannot say what the spot is. A suspicious ultrasound is followed by a contrast CT or MRI, which is the test that actually makes or rules out the diagnosis.
Is CT or MRI better for the liver?
Both work when done with the right contrast timings. MRI can show small spots more clearly and avoids radiation, but takes longer and is harder for people who cannot lie still. CT is faster and more widely available. Your team picks the one that suits you and your kidneys.
Why did my doctor not order a biopsy?
Because in a liver with cirrhosis, a typical contrast scan is accepted as proof of HCC. A needle would add a small risk of bleeding and seldom change the plan. If the scan pattern is not typical, or your liver has no cirrhosis, a biopsy is normally arranged.
Can a biopsy spread the cancer?
There is a small risk of tumour cells being carried along the needle track. It is one reason biopsies are not done when the scan already answers the question. When a biopsy is needed, careful technique keeps that risk low, and it should not stop you having one.
What does a high AFP mean?
It means the liver is releasing more of this protein than usual. HCC is one cause, but hepatitis flares, cirrhosis and pregnancy can raise it too. A high AFP leads to a contrast scan. It is never a diagnosis on its own, and a normal value never rules cancer out.
Do I need a PET-CT scan?
Not usually to make the diagnosis. Many liver cancers do not show up well on a standard PET scan. It may be used later to look for spread outside the liver in some situations. Your oncologist will say whether it adds anything in your case.
Why are they testing me for hepatitis?
Because hepatitis B and C are common causes of liver cancer in India, and both can be treated or controlled. Treating the virus protects the rest of the liver during cancer treatment. Household members may be advised to get tested too, which is about protection, not blame.
Can CION review scans done at another hospital?
Yes. Bring the original images on a disc or a download link, along with the reports and recent blood results. The tumour board can review them and tell you whether the diagnosis is secure or whether another test is needed before treatment is planned.
