How radioembolisation (Y-90) differs from TACE | CION Cancer Clinics
Y-90 and TACE both treat liver cancer through the artery that feeds the tumour. TACE delivers chemotherapy and then blocks the artery; Y-90 delivers tiny radioactive beads that treat the tumour from inside with little blocking. This page explains how they differ in practice, who each one suits, what the extra planning for Y-90 involves and how your team chooses between them. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
What is the real difference between Y-90 and TACE?
Both treatments reach a liver tumour through the artery that feeds it. TACE sends chemotherapy and then blocks that artery, so the tumour is starved and poisoned at the same time. Y-90, also called TARE or radioembolisation, sends millions of tiny beads carrying radiation, which lodge in the tumour and treat it from the inside.
Who this page is for
This page is about hepatocellular carcinoma (HCC), the cancer that starts in the liver itself, usually in a liver already scarred by cirrhosis. If your cancer began in the bowel, breast or elsewhere and has spread to the liver, the reasoning is different. Start with Y-90 for liver metastases instead.
Why the difference matters to you
The two are not interchangeable. They differ in how much they block blood flow, in how they feel afterwards, in the tests needed first, and in cost. Some people can have one but not the other. Your tumour board decides which suits your tumour and your liver, not which one is newer.
Neither treatment is usually expected to remove the cancer for good on its own. Both are about control.Side by side
How do TACE and Y-90 compare, point by point?
TACE (chemoembolisation)
Y-90 (radioembolisation)
Chemotherapy is mixed with oil or loaded onto beads
Tiny glass or resin beads carry a radioactive element
The artery is deliberately blocked to starve the tumour
The beads are so small that blood flow is only lightly reduced
No separate planning procedure is usually needed
A mapping scan comes first, on a separate visit
Often repeated several times over months
Often one or two treatments in all
Pain, fever and sickness afterwards are common
Tiredness is the most common complaint; pain is usually milder
Usually avoided if the main portal vein is blocked by tumour
Can sometimes be used when the portal vein is involved
Widely available across Indian cities
Offered at fewer hospitals, and costs considerably more
Not sure whether this applies to you?
Ask an oncologistThe decision
What makes the team choose one over the other?
The choice rests on three things: the tumour, the liver around it and the person carrying both.
The tumour
Size, number and position matter. A large single tumour, or tumour growing into a branch of the portal vein, tends to push the team towards Y-90. Several moderate tumours in a liver that copes well often suit TACE.
The liver
Both treatments put strain on liver that is already damaged. A raised bilirubin (the yellow pigment behind jaundice), fluid in the abdomen (ascites) or a poor Child-Pugh score can rule out either one.
The blood vessels
For Y-90 the beads must stay in the liver. If the mapping scan shows too much would reach the lungs or the stomach, Y-90 is not safe and TACE or another option is used.
The person and the practicalities
Fitness, other illnesses, how far you travel and what the family can afford all count. These are fair things to raise.
- How many hospital visits you can manage
- Whether surgery or transplant is still the goal
- Whether Y-90 is available near you
The journey
How do the steps differ from start to finish?
Planning
For TACE, the tumour board reviews your triple-phase CT or MRI and the procedure is booked. For Y-90, there is an extra step: a mapping scan that rehearses where the beads would go and helps set the dose.
The procedure
Both are done by an interventional radiologist through a thin tube passed from the groin or wrist into the liver artery. You are awake but sedated. CION coordinates both through NABH-accredited partner hospitals.
The first few days
After TACE, many people feel feverish, sore and sick for a few days. This is called post-embolisation syndrome. After Y-90, tiredness is more typical, and you are given simple radiation safety advice for home.
Checking the result
A repeat scan some weeks later shows how the tumour has responded. With TACE, the team then decides whether another session is needed. With Y-90, the effect builds slowly, so patience is part of the plan.

Commonly believed
Is Y-90 simply a better, newer TACE?
"Y-90 is newer, so it must work better."
Trials comparing the two have not shown one clearly helping people live longer than the other. Y-90 may be gentler for some and better suited to certain tumours. It is a different tool, not an upgrade.
"Radiation means I will be dangerous to my family."
The radiation stays almost entirely inside the liver and fades away on its own. You will be told about a short period of simple precautions, such as not holding small children on your lap for long.
"If TACE stops working, nothing else can be done."
When TACE stops controlling the tumour, the team looks again. Y-90, ablation, radiation or medicines such as immunotherapy may all be considered.
"The costlier treatment is always the right one."
Price reflects the materials, not the benefit to you. Many people are well served by TACE. Ask why a treatment is being recommended for your liver specifically.
Not for everyone
Who does neither treatment suit?
Both treatments are for cancer that is mainly inside the liver. If the cancer has spread to the bones, lungs or lymph nodes, treating the liver alone rarely helps, and medicines that work through the whole body are usually the better first step.
When the liver is too weak
If you have jaundice from the cirrhosis itself, ascites that keeps coming back, or episodes of confusion from the liver (hepatic encephalopathy), either procedure could tip the liver into failure. In that situation the team focuses on protecting the liver and on comfort, and may talk about whether a transplant assessment makes sense.
When Y-90 in particular does not suit
Y-90 is set aside if the mapping scan shows too much flow to the lungs, or flow to the stomach or bowel that cannot be closed off. It is also harder to arrange if you cannot travel to a hospital that offers it.
When TACE in particular does not suit
TACE is usually avoided when tumour blocks the main portal vein, because cutting the artery as well could starve healthy liver. Very large tumours also respond less well to it.
Being straight with you
What this page cannot tell you
It cannot tell you which treatment is right for your liver. That depends on your scans, your blood tests and how the two fit with any plan for surgery or transplant. The tumour board makes that call with all of them in front of it.
It cannot predict how you will respond
Responses vary widely between people with tumours that look alike on a scan. Nobody can honestly promise a result from either procedure before it is done, and you should be wary of anyone who does.
It cannot give you a price
Y-90 is quoted separately and varies by hospital, by the type of bead and by how much liver is treated. Ask for a written, itemised estimate for whichever option is proposed. The details of the procedure itself are on our Y-90 technique page.
If you have been offered one and want to ask about the other, call the helpline. A second opinion is a normal request.Questions we are asked
Common questions about Y-90 and TACE
Which is more effective, Y-90 or TACE?
Neither has been shown to be clearly better for everyone. Each suits different tumours and different livers. Y-90 tends to be chosen for larger tumours or portal vein involvement, and TACE for several moderate tumours in a liver that copes well. Your team will explain why one fits you.
Is Y-90 less painful than TACE?
Usually, yes. Because Y-90 blocks the artery much less, the pain, fever and sickness common after TACE tend to be milder. Tiredness is the main complaint after Y-90 and can last a while. Both are done under sedation, so the procedure itself is not usually painful.
Why does Y-90 need a scan beforehand when TACE does not?
Radiation beads cannot be pulled back once they are released. The mapping scan checks that they would stay in the liver and not travel to the lungs, stomach or bowel. It also helps work out the dose. TACE has no radiation, so this rehearsal is not needed.
Can I have Y-90 after TACE has stopped working?
Sometimes. If the cancer is still mainly in the liver and the liver is coping, Y-90 can be considered. Often the team moves to medicines that work through the whole body instead. The tumour board weighs your latest scan and blood tests before deciding.
Can either treatment get me to surgery or transplant?
Both are sometimes used to keep a tumour in check while someone waits for a transplant, or to shrink it towards an operation. Whether that is realistic depends on your tumour and your liver. Ask your team directly whether this is the aim in your case.
Is Y-90 available in Hyderabad?
Y-90 is offered at fewer hospitals in India than TACE, and availability can change. The beads are often imported, which affects timing. CION can find out where it is currently offered and coordinate it through a partner hospital if it suits you.
Do Aarogyasri or insurance cover these treatments?
Schemes and insurers decide what they cover, and the details change. TACE is more often covered than Y-90. Check with your scheme or insurer before the procedure is booked, and ask the hospital for a written estimate. CION can help with the paperwork.
Can I take my reports for a second opinion?
Yes. Bring your recent CT or MRI, your blood test reports and any previous procedure notes. A CION medical oncologist can review them with the tumour board and explain whether TACE, Y-90 or something else fits your liver and your goals.
