Why the tumour is only half the decision in liver cancer | CION Cancer Clinics
In primary liver cancer, treatment is chosen by the tumour and by how well the rest of the liver works. A treatment that suits the tumour can be unsafe if the liver is already weak. This page explains what the team weighs, the liver words on your report, and why two people with the same tumour can be offered different plans. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
Why does my liver function matter as much as the tumour?
In primary liver cancer, the treatment is chosen by two things at once: the tumour, and how well the rest of the liver still works. A treatment that suits the tumour can be unsafe if the liver around it is already struggling. That is why two people with the same tumour on the scan can be offered very different plans.
Most liver cancers grow in a damaged liver
Hepatocellular carcinoma (HCC), the commonest primary liver cancer, usually grows in a liver already scarred by hepatitis B or C, alcohol or fatty liver. That scarring is called cirrhosis. Surgery removes liver, TACE blocks the blood supply to part of it, and some medicines are processed by it. Each one asks the remaining liver to cope. If it cannot, the treatment can do more harm than the cancer.
Which liver cancer this page is about
This page is about cancer that started in the liver. If your scan shows cancer that has spread to the liver from the bowel, breast or elsewhere, the rules are different. Start with the two very different things called liver cancer.
A small tumour in a weak liver can be harder to treat than a larger tumour in a healthy one.Three things, not one
What does the team actually weigh before choosing a treatment?
Liver cancer teams look at three separate questions. A plan only works when all three answers point the same way.
The tumour
How many tumours there are, how big, where they sit, and whether they have grown into the main blood vessels or spread outside the liver.
Comes from
- Triple-phase CT or MRI of the liver
- Sometimes a biopsy
- The AFP blood test, a tumour marker
The liver
How much working liver is left and how well it does its jobs. This is often summarised as Child-Pugh A, B or C, where A is the best preserved and C the most damaged.
Comes from
- Bilirubin, albumin and INR blood tests
- Whether there is fluid in the abdomen (ascites)
- Any confusion caused by the liver
- Signs of high pressure in the liver veins
The person
How you are managing day to day, your heart, lungs and kidneys, and what you want from treatment. Doctors call the first part performance status.

Ask an oncologistHow it comes together
How do the tumour and the liver get combined into one plan?
The scans describe the tumour
A radiologist reports the size, number and position of the tumours, and whether the portal vein, the main vein into the liver, is involved. CION arranges these scans through diagnostic partners.
The blood tests describe the liver
Bilirubin, albumin and INR show how well the liver is making proteins and clearing waste. Together with ascites and confusion, they give the Child-Pugh grade.
A staging system puts both on one line
Most teams use the BCLC system. Unlike the stage one to four used for other cancers, it counts the tumour, the liver and your fitness together, and links each stage to the treatments that usually suit it.
The tumour board decides
Oncologists, surgeons, radiologists and liver specialists review everything together at the liver tumour board. They check that the plan the tumour needs is one the liver can survive.
On your report
What do the liver function words on my report mean?
- Bilirubin
- A yellow waste product the liver clears. When it rises, the liver is struggling, and the skin or eyes may turn yellow.
- Albumin
- A protein the liver makes. A low level means the liver is making less than the body needs.
- INR
- A measure of how quickly blood clots. The liver makes clotting proteins, so a high INR can mean liver damage.
- Child-Pugh A, B or C
- A grade built from these tests plus ascites and confusion. Most treatments that remove or attack liver tissue need a liver near the A end.
- Portal hypertension
- High pressure in the veins feeding the liver, caused by scarring. It can make surgery risky even when the blood tests look reasonable.
- Performance status
- How much of your normal day you can manage. It tells the team how well you are likely to cope with treatment.

Commonly believed
What do families often get wrong about liver cancer treatment?
"The tumour is small, so they should just operate."
Size is only half of it. In a scarred liver, removing even a small part can leave too little working liver behind. For some people, ablation or a transplant is safer than an operation for the very same tumour. Why surgery is often impossible in cirrhosis explains this.
"Another hospital offered surgery, so this one must be wrong."
Different advice often comes from a different reading of the liver tests, not of the tumour. Ask each team what they think of your liver function. That question usually explains the gap.
"If the liver is weak, nothing can be done."
A weaker liver narrows the choices. It does not end them. Symptom care, treating the cause of the liver damage and sometimes a transplant assessment are still on the table.
"Liver function is fixed, so the plan cannot change."
Liver function can improve, for example after stopping alcohol, controlling hepatitis B or clearing hepatitis C. When it does, the team may look at the options again.
Not everyone
Who does this way of deciding not apply to?
This two-sided decision is mainly about HCC in a liver with cirrhosis or other long-term liver disease. It applies less strongly in a few situations, and you should know if you are in one of them.
Cancer in a liver that was otherwise healthy
Some people develop HCC in a liver without cirrhosis, sometimes linked to hepatitis B or fatty liver. Here the liver usually copes well, and the tumour itself drives most of the decision. Larger operations may be possible. See HCC without cirrhosis.
Cancer that spread to the liver
For cancer that came from the bowel, breast, pancreas or elsewhere, the plan is led by where it started. The liver usually works normally.
Bile duct cancer and children
Bile duct cancer inside the liver is staged and treated differently. Liver tumours in children, such as hepatoblastoma, are covered on a separate page.
Being straight with you
What this page cannot tell you
It cannot tell you which treatment suits you. That depends on the exact values on your blood reports, the detail on your scans, and a doctor examining you. Two reports that look alike to a family can mean different things to the team.
It cannot grade your liver from a report alone
Child-Pugh and BCLC need information that is not printed on a single lab sheet, such as how much fluid is in the abdomen or whether there has been confusion. Please do not try to work out a grade at home and act on it.
It cannot predict how things will go
Liver function affects outlook as well as treatment, but no page can turn that into a forecast for one person. Your oncologist can talk you through what the results mean for you.
If you have a plan in hand and do not understand why it was chosen, bring the scans and reports to CION for a second opinion. The tumour board will explain both halves of the decision.Questions we are asked
Common questions about liver function and treatment
Why did the doctor ask about my liver tests before the tumour?
Because liver function decides which treatments are safe. If the liver is already weak, some options are ruled out before the tumour is even measured. Starting with the liver avoids offering a plan the body cannot tolerate, and it explains why the first visit often includes several blood tests.
What does Child-Pugh A mean for treatment?
It means the liver is working relatively well. Most treatments, including surgery, ablation, TACE and many medicines, are usually considered first in people with Child-Pugh A. Being grade A does not settle the choice on its own, because the tumour and your fitness still matter. See Child-Pugh explained.
Can I have surgery if I have cirrhosis?
Sometimes. It depends on how well the liver works, whether there is high pressure in the liver veins, and how much liver would be left after the operation. CION's surgical oncologists assess this with the team. Your team will tell you where the operation would take place if it is advised.
Why was I offered ablation instead of surgery?
Ablation destroys a small tumour with heat passed through a needle, so it removes far less liver than an operation. In a scarred liver that can be the safer way to treat the same small tumour. The team will explain why they preferred it in your case.
Can my liver function get better?
It can, in some people. Stopping alcohol, controlling hepatitis B with tablets, treating hepatitis C and managing fluid and nutrition can all help. A hepatologist guides this. If liver function improves, the team may review the treatment choices again.
Should we cut protein to protect the liver?
Usually not. Many families cut protein, but people with cirrhosis often need more of it to keep their muscles, and muscle loss narrows treatment options. Ask the team or a dietitian before changing the diet, especially if there has been confusion.
Does a transplant treat both problems?
A transplant replaces the whole liver, so it deals with the tumour and the damaged liver together. It suits only some people, within strict limits on the tumour. CION coordinates assessment with licensed transplant centres. See transplant for liver cancer.
How do I get both halves of my case reviewed?
Bring every scan on disc, the radiology reports, recent blood tests and a list of your medicines. Call the CION helpline, and the case can be reviewed by the liver tumour board. The team will explain how your tumour and your liver each shaped the advice.
