It Sorts People into Risk Levels
Risk stratification helps target screening efficiently. People at higher risk can be checked more carefully than people at lower risk.
AI Summary A liver cancer risk score estimates how likely a person with liver disease is to develop hepatocellular carcinoma (HCC). It does not diagnose cancer. Cirrhosis from any cause is the strongest risk factor, and chronic hepatitis B or C, fatty liver disease with cirrhosis, and heavy alcohol use also raise risk. People at high risk are advised to have an ultrasound and AFP blood test about every six months. Treating the underlying liver disease helps lower risk.

Medically Reviewed.
A liver cancer risk score estimates how likely a person with liver disease is to develop hepatocellular carcinoma (HCC), the most common type of liver cancer. Doctors use these estimates to decide who needs regular checks.
This page explains who is at higher risk, what risk numbers look like, how scores fit with ultrasound and blood-test surveillance, and what you can do to lower your risk.

OVERVIEW of cancer risk score
What Is a Liver Cancer Risk Score?
Liver cancer takes time to develop. In people with chronic liver disease, it can take years or even decades. That long window gives doctors a chance to act early, and a risk score helps them decide where to focus.
Think of a risk score as a forecast, not a scan. It does not look inside your liver. It pulls together what is already known about you, such as the cause of your liver disease and how much damage you have, and places you in a lower-risk or higher-risk group. Newer approaches also add blood-based biomarkers to clinical details.
These scores focus on hepatocellular carcinoma (HCC), one of the two most common cancers that start in the liver. Cancer that starts elsewhere and spreads to the liver is called metastatic cancer. It is a different condition.
What to Know About Liver Cancer Risk Scores
- Cirrhosis from any cause is the strongest risk factor for HCC. It is present in over 80% of people with HCC.
- About 1–8% of people with cirrhosis develop HCC each year, depending on the cause of their liver disease.
- Risk stratification helps target screening. Current clinical models perform moderately well.
- A risk score does not diagnose cancer. Surveillance uses ultrasound plus an AFP blood test about every six months.
RISK FACTORS
Who Has a Higher Liver Cancer Risk
Risk scores weigh factors like these. In general, the more liver damage a person has, the higher the risk.
Liver Conditions
- Cirrhosis from any cause
- Chronic hepatitis B or hepatitis C
- Fatty liver disease (MAFLD) with cirrhosis
- Long-term heavy alcohol use
- A past liver cancer, including after hepatitis C is cured with direct-acting antivirals
Other Factors
- Inherited iron overload (hereditary hemochromatosis) and Wilson disease
- Work exposure to solvents, pesticides, or insecticides
- Regular work contact with people who have hepatitis B or C
- Smoking
Why This Matters
No single factor tells the whole story. A risk score weighs several factors together to help your care team decide how closely to check you.
RISK IN NUMBERS
Liver Cancer Risk in Numbers
Your own risk depends on your cause of liver disease and your overall health.
- 1–8% per year: share of people with cirrhosis who develop HCC, depending on the cause (hepatitis B, hepatitis C, or fatty liver disease).
- 10–30% over ten years: cumulative risk in high-risk groups, such as people with chronic viral hepatitis or advanced fibrosis.
- 1–1.5% per year: HCC rate in people with MAFLD-related cirrhosis.
- 0.08–0.63 per 1,000 person-years: HCC rate in people with MAFLD but no cirrhosis. Routine screening is not currently recommended for this group.
- 8–10%: estimated share of people with hereditary hemochromatosis who develop HCC.
- 29.6%: share of 602 people with a past HCC whose cancer returned after hepatitis C cure with direct-acting antivirals, over an average of 15.4 months.
HOW IT WORKS
How Doctors Use a Risk Score
A risk score helps match the intensity of checks to the level of risk.
It Can Combine Blood Markers with Clinical Details
Blood-based biomarkers may improve how well a model predicts cancer. Combining them with clinical features may reach a prediction accuracy of 0.8–0.9. Our GALAD Score page covers one score that follows this approach.
It Has Limits
Current clinical models perform moderately well but have limited real-world impact. A score cannot tell you that cancer is present or absent. Surveillance tests and imaging do that.
It Guides a Plan, Not a Diagnosis
Surveillance is individualized by weighing benefits and harms. Your liver specialist uses your risk, test results, and preferences to set your schedule.
COMPARE
Risk Score vs. Other Liver Cancer Tests
A risk score and a surveillance test answer different questions.
| Tool | What It Tells You | When It Is Used |
|---|---|---|
| Liver cancer risk score | How likely cancer is to develop over time | To decide how closely to check someone with liver disease |
| Ultrasound plus AFP blood test | Whether a tumor may be present now | About every six months in people at high risk |
| Contrast-enhanced CT or MRI | A clearer picture of the liver | When ultrasound views are poor, or a finding needs a closer look |
| Liver biopsy | Whether a suspicious lesion is cancer | When a lesion stays suspicious after MRI |
AFP (alpha-fetoprotein) is a tumor marker. An AFP above 15 ng/mL should raise suspicion for cancer, but it does not confirm it.
LOWER YOUR RISK
What You Can Do About Your Risk
You cannot change every risk factor, but some steps help.
Treat the Underlying Liver Disease
Antiviral therapy is the most effective way to prevent HCC. People with hepatitis B can read about HBV antivirals.
Keep Your Surveillance Appointments
Early liver cancer often causes no symptoms, so scheduled checks are how most tumors are found early. Ask your care team how often you need an ultrasound and AFP test.
Support Your Liver with Daily Habits
Diet, exercise, avoiding alcohol, and quitting tobacco are recommended for liver protection, though evidence that they prevent cancer directly is limited. Lifestyle changes should not replace other care. It is best not to drink alcohol.
Support Your Diet Alongside Your Care
Amsety Bars were designed for people with liver conditions by liver health experts. They offer a convenient way to add energy and nutrients to a liver-friendly diet. Ask your provider what fits your needs.

NEXT STEPS
Next Steps After Your Risk Check
Once you know your risk group, these steps help you act on it.
Ask Which Risk Group You Are In
Your risk depends on the cause of your liver disease and how much damage you have. Ask your care team how they see your risk and what it means for your checks.
Confirm Your Surveillance Plan
For people at high risk, guidelines prefer an ultrasound plus an AFP blood test about every six months. Ask when your next appointment is due and whether you need CT or MRI.
Learn How Liver Cancer Is Treated
If cancer is ever found, treatment depends on the liver's condition and the extent of cirrhosis, the size, location, and number of tumors, whether the cancer has spread, and your overall health. Knowing the options ahead of time can make those talks easier.

Common Questions
Answers to Common Liver Cancer Risk Score Questions
What Is a Liver Cancer Risk Score?
A liver cancer risk score is an estimate of how likely a person with liver disease is to develop hepatocellular carcinoma (HCC). It helps doctors decide who needs regular checks. It does not show whether cancer is present today.
Can a Risk Score Diagnose Liver Cancer?
No. A risk score estimates future risk only. Diagnosis relies on imaging such as contrast-enhanced CT or MRI, and on a biopsy if a lesion stays suspicious. AFP alone cannot diagnose liver cancer.
Who Is at Risk for Liver Cancer?
People with cirrhosis from any cause have the highest risk. Chronic hepatitis B or C, fatty liver disease with cirrhosis, heavy alcohol use, hemochromatosis, and a past liver cancer also raise risk.
How Often Should I Be Checked for Liver Cancer?
Guidelines prefer an ultrasound plus an AFP blood test about every six months for people at high risk. If ultrasound views are poor, contrast-enhanced CT or MRI is recommended. Your specialist sets your schedule.
Do I Need Checks If I Have Fatty Liver Disease?
Not always. Screening is recommended for adults with MAFLD-related cirrhosis, but routine screening is not currently recommended for MAFLD without cirrhosis, because the yearly rate is much lower. Ask your doctor about your stage of liver disease.
Can I Lower My Liver Cancer Risk?
Yes, in part. Treating the underlying disease, especially with antiviral therapy for hepatitis, is the most effective prevention. Avoiding alcohol, not smoking, eating well, and staying active support liver health, though their direct effect on cancer prevention is less proven.
