Fever in liver cancer: is it an infection or the tumour? | CION Cancer Clinics
Treat any new fever in liver cancer as an infection until a doctor has checked. Infections in the abdominal fluid, the bile ducts or a stent are common, can worsen fast and respond well to early antibiotics. Fever from the tumour itself is real but is diagnosed only after infection is ruled out. This page explains the usual causes, the signs that mean hospital today and what the doctor will test. At CION Cancer Clinics, our team supports patients and families through symptoms, follow-up and life during and after treatment.

The short answer
Is a fever in liver cancer coming from an infection or from the tumour?
Treat every new fever as an infection until a doctor has ruled that out. Infection is common in people with liver cancer and cirrhosis, it can get worse quickly, and it is very treatable when it is caught early. Fever from the tumour itself does happen, but doctors only call it that after they have looked for infection and found none.
Why the liver changes the picture
A healthy liver helps clear bacteria from the blood. When it is scarred by cirrhosis or crowded by a tumour, that filter works less well. Fluid in the abdomen, a blocked bile duct or a stent can also give bacteria somewhere to settle. So an infection that would stay small in another person can spread faster here, sometimes with only a mild fever or none at all.
Who this page is for
It is written for people with primary liver cancer, often with cirrhosis, and for cancer that has spread to the liver from somewhere else. If you are on chemotherapy for another cancer, the fever rules from that treatment apply first. Your oncologist's instructions always come before anything written here.
A fever is a reason to call, not a reason to wait and see.Where fevers come from
What usually causes a fever in someone with liver cancer?
Most fevers have an ordinary cause that can be found and treated. These are the ones your team will think about first.
Infection in the abdominal fluid
When fluid collects in the abdomen (ascites), it can become infected without any cut or procedure. This is called spontaneous bacterial peritonitis. It may show as fever, belly pain or simply new confusion. Read more on infection in the fluid.
A blocked bile duct or stent
When bile cannot drain, it can become infected. This is called cholangitis. Fever with shivering, yellow eyes and pain under the right ribs together point here. See blocked stents and fever.
After a procedure
Fever, pain and nausea for a few days after TACE or ablation are common and are called post-embolisation syndrome. It usually settles on its own. A fever that climbs, or comes back later, needs checking for an abscess.
Everyday infections
Chest, urine and skin infections, dengue and typhoid all happen to people with liver cancer too.
Also on the list
- A side effect of immunotherapy or another medicine
- A low white cell count during chemotherapy
- The tumour itself, once infection is excluded
Not sure whether this applies to you?
Ask an oncologist
!
Go to hospital today
Do not wait for a clinic appointment if a fever comes with any of these: fluid in the abdomen, new or worse belly pain, yellow eyes that appeared suddenly, shivering fits, new confusion or drowsiness, vomiting blood or passing black stools, or very little urine. Go to the nearest emergency department the same day, say the person has liver cancer and take their reports and medicine list. For any other fever, call your oncology team the same day.
At the hospital
What will the doctor do to find the cause?
Examine and ask questions
When the fever started, any recent procedure, new medicines, stent, cough, burning urine or belly pain. The answers narrow the search quickly, so bring the discharge summaries.
Blood tests and cultures
A blood count, liver and kidney tests, and blood cultures, which grow any bacteria in the blood so the right antibiotic can be chosen. Culture results take time, so treatment often starts before they come back.
A sample of the fluid
If there is ascites, a small amount is drawn off with a thin needle and tested. This is the only reliable way to know whether the fluid is infected.
A scan if needed
An ultrasound or CT can show a blocked bile duct, a blocked stent or an abscess. CION arranges these through its diagnostic partners when they are needed.
Treatment, then review
Infections are treated with antibiotics, and a blocked duct may need a new stent. Your cancer treatment may pause briefly. The oncology team then decides when to restart.
On the discharge summary
What do the words on the report mean?
- SBP
- Spontaneous bacterial peritonitis. An infection of the fluid in the abdomen that starts without any obvious cause.
- Cholangitis
- Infection of the bile ducts, usually because bile is not draining. It often needs the blockage relieved as well as antibiotics.
- Tumour fever
- A fever caused by substances the cancer releases. It is a diagnosis made only after infection has been looked for and not found.
- Post-embolisation syndrome
- Fever, pain and tiredness for a few days after TACE, as the treated tumour breaks down. Expected, but still worth reporting.
- Blood culture
- A blood sample left to grow, to see whether bacteria are present and which antibiotic will kill them.

Commonly believed
What do families get wrong about fever in liver cancer?
"It is only a mild fever, so it can wait until the next visit."
In cirrhosis, a serious infection can show only a mild temperature, or none. Confusion, sleepiness or less urine can be the first sign. How unwell the person looks matters more than the number on the thermometer.
"Paracetamol brought it down, so the problem is solved."
Paracetamol lowers the temperature but does nothing to the infection underneath. It is often allowed in liver disease at the amount your doctor sets. Watch for cold medicines that contain it too; see paracetamol hidden in cold medicines.
"Fever means the cancer is spreading."
Usually it does not. Most fevers in this setting are infections or procedure reactions. Assuming it is the cancer can delay an antibiotic that would have fixed the problem.
"Leftover antibiotics at home will do."
The wrong antibiotic can hide an infection without clearing it, and some are hard on a damaged liver or the kidneys. Let the treating doctor choose.
Being straight with you
What this page cannot tell you
It cannot tell you what is causing this fever, in this person, today. That needs an examination, blood tests and sometimes a sample of fluid or a scan. Nobody can tell infection from tumour fever over the phone or from a description.
It cannot replace the instructions you were given
People on immunotherapy, targeted therapy or chemotherapy each get their own fever rules. Immunotherapy can also inflame the liver, which has its own page on immune hepatitis. Follow the plan your oncologist wrote for you.
Who this does not apply to
It does not cover fever after a liver transplant, which has its own rules and its own team, or fever in a child. If jaundice and itching are troubling you without a fever, those are treatable too; see itching and what helps.
If you are unsure whether a fever needs hospital, call the CION helpline and describe it. Someone will tell you plainly.Questions we are asked
Common questions about fever in liver cancer
Can liver cancer itself cause a fever?
Yes. Some liver tumours release substances that raise body temperature, and large tumours can break down inside. But this is decided only after infection has been looked for properly. Calling a fever a tumour fever too early is how treatable infections get missed.
Is fever after TACE normal?
A low fever with pain and nausea for a few days after TACE is common and usually settles with rest and simple medicines. Call the team if the fever is high, lasts longer than you were told to expect, or comes back after it had settled. That pattern can mean an abscess.
Why did the doctor take fluid from the belly for a fever?
Because infection of the abdominal fluid is common in people with ascites and can be found only by testing the fluid. It is done with a thin needle and a small sample. Finding it early means antibiotics can start quickly.
My father has a stent and now has fever and shivering. What should we do?
Take him to hospital today. Fever and shivering with a bile duct stent can mean the stent is blocked and the bile is infected. This usually needs antibiotics and often a stent change, and it should not wait for a clinic appointment.
Will the fever delay cancer treatment?
Often for a short time. An active infection is treated first, because cancer treatment given during an infection can make both worse. Once the infection is controlled, your oncologist will restart the plan, sometimes with small changes.
Can immunotherapy cause fever?
It can, either as a reaction around the time of the drip or later, when the immune system inflames an organ such as the liver, lungs or bowel. Any fever on immunotherapy should be reported the same day, so the team can tell a side effect from an infection.
Can we just give paracetamol and watch at home?
Only if your team has already told you that is safe for this person. Paracetamol can hide a rising temperature, and the amount allowed depends on the liver. If there is fluid in the abdomen, confusion, jaundice or shivering, go to hospital instead.
Who do we call at night?
For any red-flag sign, go straight to the nearest emergency department and show the reports. For a fever without those signs, call the CION helpline. One helpline serves every centre, and someone will tell you whether to come in.
