The day of your liver ablation, from arrival to going home | CION Cancer Clinics
On the day of liver ablation you arrive fasting, have checks and a drip, and are sedated or put to sleep. A radiologist guides a thin needle into the tumour and heats it until the cancer cells die. Most people rest in hospital afterwards and many go home the next day. This page walks through each step, what to bring and which signs mean coming back. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
What actually happens on the day of a liver ablation?
You arrive having not eaten, have a few checks and a drip, and are given sedation or a general anaesthetic. A radiologist then guides a thin needle through the skin into the tumour and heats it until the cancer cells die. Most people rest in hospital afterwards and many go home the next day.
Why it feels smaller than an operation
There is no large cut. The needle goes in through a nick in the skin about the width of a pen tip, and the work is done inside the liver. For a small hepatocellular carcinoma (HCC, cancer that starts in the liver), this can be a curative treatment, which is why the day matters so much to the people going through it.
Who arranges it
Your CION oncologist and the liver tumour board decide whether ablation suits you. The procedure itself is done by interventional radiologists, and CION coordinates it through NABH-accredited partner hospitals. If you are still deciding between treatments, start with our page on ablation versus surgery.
The details below are the usual pattern. Your hospital's written instructions always come first.Getting ready
What do I need to do before the day of ablation?
Most of the preparation happens in the days before. Getting it right avoids a cancelled slot and a wasted journey.
Blood tests
Your clotting, platelet count and liver function are checked beforehand. A liver with cirrhosis can bleed more easily, so a low platelet count or a high INR (a measure of how slowly blood clots) may need correcting first.
Your medicines
Tell the team about every tablet you take, including blood thinners, aspirin, diabetes medicines and any herbal or Ayurvedic liver tonics. Some must be paused. Do not stop anything on your own; wait to be told which and when.
Fasting
You will be told when to stop eating and drinking. Follow it exactly, because the sedation or anaesthetic is only safe on an empty stomach.
What to bring
- All scan reports and the images on a disc or link
- Recent blood reports and your medicine list
- Scheme or insurance papers and photo ID
- One adult who can stay and take you home

What happens, step by step, on the day of ablation?
Arrival and checks
A nurse checks your name, the planned procedure, your blood results and your fasting. A drip is placed in your arm. You sign a consent form after the doctor explains the risks. Ask anything you are unsure about at this point.
Sedation or anaesthetic
Depending on the hospital and the tumour, you are either deeply sedated and drowsy, or fully asleep under a general anaesthetic. The skin over the liver is cleaned and numbed.
Finding the tumour
The radiologist uses ultrasound or CT to see the tumour and plan the path of the needle, avoiding blood vessels, the bowel and the gallbladder.
The ablation
The needle is placed into the tumour and the energy is switched on. The aim is to destroy the tumour and a thin rim of liver around it. A large tumour may need the needle moved more than once.
Recovery and watching
You are moved to a recovery area. Nurses check your blood pressure, pulse and the puncture site for bleeding, and give pain relief. Most people stay overnight.

When to go back to hospital today
After you go home, go to hospital the same day if you have severe or worsening pain in the abdomen or shoulder, a fever with shivering, vomiting blood or black stools, new yellowing of the eyes, new confusion or drowsiness, or feeling faint. Do not wait for your follow-up appointment.

On your discharge papers
What do the words on my ablation report mean?
- RFA
- Radiofrequency ablation. Heat made by an electrical current at the tip of the needle.
- MWA
- Microwave ablation. Heat made by microwaves, which can heat a larger area faster.
- Ablation zone
- The area of dead tissue left after treatment. It is meant to be larger than the tumour.
- Margin
- The rim of healthy liver destroyed around the tumour, so no edge of cancer is missed.
- Track ablation
- Heating the needle path on the way out, to reduce the small risk of leaving cancer cells along it.
Did you know
A mild fever, aches and tiredness for a few days afterwards are common. This is called post-ablation syndrome and is the body clearing the dead tissue. It is different from the high fever with shivering that needs a doctor. Our page on post-ablation syndrome explains how to tell them apart.
Being straight with you
What this page cannot tell you
It cannot tell you exactly how your day will run. Fasting rules, the type of anaesthetic, and how long you stay differ between hospitals and depend on your tumour and your liver. The written instructions from the hospital doing your procedure are what you follow.
It cannot tell you whether the ablation worked
Nobody can tell that on the day. A contrast scan some weeks later shows whether the whole tumour was destroyed, which our page on the follow-up scan after ablation explains. If a small part remains, the treatment can often be repeated.
Who this does not apply to
This page describes ablation through the skin for a tumour in the liver. It does not describe ablation done during an open or keyhole operation, or TACE, which treats a tumour through its blood supply. If your cancer spread to the liver from the bowel, your team may plan the day differently.
Questions we are asked
Common questions about the day of ablation
Will I be awake during liver ablation?
Usually not fully. Most people have either deep sedation, where you are drowsy and remember little, or a general anaesthetic, where you are asleep. The choice depends on the tumour's position and the hospital. You will be told beforehand which to expect.
Does liver ablation hurt?
You should not feel the procedure itself. Afterwards there is often pain under the right ribs, and sometimes in the right shoulder, because nerves from the liver share a pathway with it. Pain relief is given, and it usually settles within a few days.
How long does the procedure take?
The ablation itself is usually shorter than people expect. Preparation, sedation and recovery take longer than the treatment. Plan on spending most of the day in hospital, and possibly a night. Your hospital can give you a better estimate for your case.
Can a family member stay with me?
A family member can usually wait nearby and be with you before and after, though not in the procedure room. You should not travel home alone or drive after sedation. If you have come from a district, plan to stay near the hospital until you are discharged.
When can I eat again?
Usually once you are fully awake and the nurses are happy with your checks. Start with something light. If you have cirrhosis, keep eating enough protein afterwards. Cutting protein to protect the liver is a common belief, and it often does more harm than good.
When can I go back to work?
Many people return to light work and normal daily life within a few days to a week. Heavy lifting and hard physical work wait a little longer. Our page on recovery after ablation covers this in more detail.
What if the procedure is cancelled on the day?
It happens, most often because a blood test shows bleeding risk, you have a fever, or fasting was not followed. It is frustrating but safer than going ahead. Your team will correct the problem and rebook. Ask them to explain the reason clearly.
Who do I call if I am worried after going home?
For severe pain, high fever, vomiting blood, yellowing or confusion, go to hospital the same day. For smaller worries, call the hospital that did the procedure or the CION helpline, and someone will advise you on what to do next.
