Liver Cancer Tests and Diagnosis

Diagnosing liver cancer is more complex than diagnosing many other cancers. That’s because, if you have liver cancer, your liver may already be damaged and both the cancer and liver function affect your outcomes.

Understanding how advanced the cancer is and how well the liver is working help your health care team recommend treatments and set realistic expectations.

The cancer experts at Banner MD Anderson Cancer Center have extensive experience diagnosing people with liver cancer and developing customized treatment plans. If you’re at high risk for liver cancer, have signs or symptoms or have already been diagnosed, our caring team of specialists can help.

How liver cancer is diagnosed

Liver cancer is usually diagnosed using a combination of medical history, physical exam, imaging and blood tests. Many people who are diagnosed with liver cancer already know they have cirrhosis or another type of liver disease and are routinely monitored for signs of liver cancer. Monitoring is only recommended for people at high risk.

Unlike many cancers, liver cancer can often be diagnosed without surgery or biopsy when imaging findings are clear.

Blood tests used in liver cancer diagnosis

Blood tests help check liver health and may help health care providers figure out if liver cancer is likely. They do not confirm liver cancer.

Alpha-fetoprotein (AFP)

AFP is a protein that could be higher than normal in people with liver cancer, especially hepatocellular carcinoma.

  • AFP is only elevated in 50% to 70% of people with liver cancer
  • AFP can rise because of noncancerous liver disease
  • Changes in AFP over time may be more helpful than a single test result

AFP alone cannot diagnose liver cancer but is useful along with imaging.

AFP blood tests are recommended every six months for people at high risk.

Liver function tests

Blood tests also measure how well the liver is working. These tests help determine:

  • What types of treatment you may be eligible for
  • How risky it is for you to have surgery
  • Your overall prognosis

Imaging tests for liver cancer

Imaging is a key method used to diagnose liver cancer.

Ultrasound

Ultrasound is a first-line screening test for people with cirrhosis or chronic hepatitis. It can look for new liver nodules that might be signs of cancer. It’s recommended every six months for people at high risk.

CT scans

Contrast-enhanced CT scans can spot liver tumors and show how they interact with nearby blood vessels. Some specialized CT scans can show a pattern that helps diagnose hepatocellular carcinoma.

MRI with liver-specific contrast

MRI is often the most accurate imaging test for liver cancer. Special contrast agents help experts tell the difference between cancer and benign liver nodules.

In many cases, characteristic imaging features are enough to confirm liver cancer.

Sometimes you can have more than one imaging test, such as CT and MRI. The information you get from two tests can help confirm the diagnosis without needing a biopsy.

When a biopsy is needed

A biopsy is a procedure where health care providers remove a small tissue sample to examine it in a lab. With liver cancer, you don’t always need a biopsy. When possible, avoiding biopsy lowers your risk of bleeding and may speed up treatment planning.

Your health care team may recommend a biopsy when:

  • Imaging findings are not clear
  • You do not have known liver disease
  • They suspect a rare tumor type
  • They aren’t sure if cancer started in the liver or metastasized (spread) there from other parts of the body

A biopsy can help identify genes, proteins and other characteristics of the tumor that can help your team select treatment options.

Liver cancer staging overview

Staging classifies liver cancer based on how far it has progressed. Unlike most cancers, liver cancer staging considers both the tumor(s) and liver function.

To stage liver cancer, providers evaluate:

  • The size of the tumor(s)
  • How many tumors there are 
  • How involved the nearby blood vessels are
  • Whether cancer has spread outside of the liver
  • How well the liver is functioning
  • Your overall health

Early-stage liver cancer

Stage I (1) liver cancer is found only in the liver. There’s usually just one tumor or a small number of tumors. In most cases, the liver is still functioning well.

At this stage:

  • Symptoms may be mild or may not exist
  • Surgery, liver-directed therapy or transplant may be treatment options
  • Curing the cancer may be the goal of treatment 

Intermediate-stage liver cancer

Intermediate-stage liver cancer means there are multiple tumors within the liver but they haven’t invaded blood vessels very much or spread to parts of the body that are far away.

  • Stage II (2): Multiple small tumors are present and/or one or more tumors has grown into surrounding tissue but has not spread to distant sites or lymph nodes
  • Stage III (3): Various large tumors or one tumor has reached a main, large blood vessel and may have spread to nearby lymph nodes but not distant sites

Treatment often focuses on:

  • Slowing the tumor growth
  • Helping the liver keep functioning
  • Keeping the disease from getting worse

Advanced-stage liver cancer

Stage IV (4) liver cancer has spread to major blood vessels or outside the liver.

At this stage:

  • Your care team may recommend treatments that affect your whole body, not just your liver
  • Treatment focuses on controlling the disease and maintaining your quality of life as much as possible

End-stage liver cancer

End-stage liver cancer causes severe liver failure and most treatment options will not help. Care often focuses on keeping you comfortable and relieving symptoms.

What prognosis means in liver cancer

Prognosis refers to how the disease is expected to change or respond over time. In liver cancer, prognosis varies widely and depends on many different factors.

Unlike cancers that develop in otherwise healthy organs, liver cancer prognosis depends on:

  • How advanced the cancer is
  • How well the liver is functioning
  • Whether treatment options are available

Factors that influence liver cancer prognosis

Key factors include:

  • The cancer stage when it’s diagnosed
  • The number and size of tumors
  • How well the liver is functioning
  • How much cirrhosis there is
  • The type of liver cancer
  • Overall health 
  • Response to treatment

People diagnosed at an early stage with good liver function often have better outcomes and more treatment options than those who are diagnosed at later stages.

How staging and prognosis guide treatment planning

Staging and prognosis help your care team better understand:

  • Which treatments are safe
  • Whether a cure may be possible
  • When you should have supportive care
