Decompression surgery when cancer has spread to the spine | CION Cancer Clinics
Decompression surgery removes the tumour and bone that are pressing on the spinal cord, so the nerves to the legs, bladder and bowel have room to work again. It is usually paired with screws and rods to steady the spine, and followed by radiotherapy. This page explains the different approaches, what the days in hospital look like, the risks, and who the operation does not suit. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What is decompression surgery for spinal metastases?
Decompression surgery removes the tumour and bone pressing on the spinal cord, so the nerves to the legs, bladder and bowel have room to work again. It is usually done together with screws and rods to hold the spine steady, and followed by radiotherapy.
What spinal metastases means
Metastases are deposits of a cancer that began somewhere else, most often the breast, lung, prostate or kidney. In the spine they settle in the bone of a vertebra. As they grow, they can push into the tunnel that carries the cord, or weaken the bone until it collapses into it.
What the operation is trying to do
The aim is to protect nerve function and ease pain, not to remove every cancer cell. The surgeon takes away enough tumour to free the cord and leaves the rest to radiotherapy and medicines. For you, a good result usually means keeping the ability to walk and control the bladder, or getting some of it back.
Decompression is one step in a larger plan. Ask your team what treatment comes after it, and when.How it is done
Which kind of decompression might be suggested?
The approach depends on where the tumour sits around the cord. Your surgeon chooses it from the MRI.
From the back
The commonest approach. A cut down the middle of the back lets the surgeon remove the bony roof of the tunnel, called a laminectomy, and clear tumour from behind and beside the cord.
Screws and rods are nearly always added, because removing bone weakens the spine further.Around the side
Through the same cut in the back, the surgeon works around the side of the cord to reach tumour in front of it. This avoids opening the chest or belly in many people.
From the front
When the tumour has destroyed the front of a vertebra, the surgeon may go in through the neck, chest or belly and replace the bone with a cage or cement. This is a larger operation.
More often considered when
- The collapse is in the neck
- A single level is badly crushed
Separation surgery
A more limited operation that clears only a thin gap between tumour and cord. Focused high-dose radiotherapy then treats the tumour left behind. Ask whether your centre offers this pairing.

What happens from admission to going home?
-
Tests before the operation
Blood tests, a heart tracing and often a chest scan, alongside the spine MRI. Tell the team about every medicine you take, especially blood thinners such as aspirin, clopidogrel or warfarin. They will decide whether and when any should be paused.
-
The operation
Under a general anaesthetic, lying face down for most approaches. It usually takes several hours. The nerves may be monitored during surgery so the surgeon is warned early if they are under strain.
-
The first night
Most people wake in a high-dependency or intensive care bed. You may have a drain in the wound and a urine catheter. Nurses check leg movement and feeling regularly.
-
Getting up
Physiotherapists usually help you sit and stand within a day or two, sometimes with a brace. Moving early lowers the chance of clots and chest infection.
-
Going home and what follows
Going home depends on walking, bladder control and pain. Radiotherapy to the operated area is usually planned once the wound has healed.
On your report
Words on the consent form and scan report, in plain language
- Laminectomy
- Removing the bony roof at the back of the spinal tunnel to give the cord more room.
- Epidural compression
- Tumour pressing on the cord from inside the tunnel but outside the cord itself. This is the usual pattern with spinal metastases.
- Posterior fixation
- Screws and rods placed from the back to hold the spine steady after bone has been removed.
- Dural tear or CSF leak
- A small tear in the lining around the cord, letting spinal fluid escape. It is usually repaired during surgery.
- Neuromonitoring
- Checking the nerve signals during the operation so the surgeon can react if they weaken.

Weighing it up
What are the risks, and who is it not suitable for?
This is a large operation on people who are often already unwell from cancer, so the risks are real. Your surgeon should go through them with you, and it is fair to ask how often they happen at that centre.
Problems that can happen
Wound infection or slow healing, particularly if radiotherapy has already been given to the same area. Bleeding. A leak of spinal fluid. Blood clots in the legs or lungs. Chest infection. Less often, the nerves are injured and weakness gets worse rather than better. Screws can loosen later if the bone around them is soft.
Who it tends not to suit
People too unwell for a long anaesthetic. People whose cancer is widespread and not responding, where recovery from the operation could take up much of the time ahead. People with tumour at many levels of the spine. People who lost all movement in the legs many days ago, because the nerves are unlikely to recover. For them, radiotherapy, pain control and a brace are usually discussed instead.
Commonly believed
Four things families believe about this operation, and what is true
"Once the surgeon removes the tumour, the cancer is gone."
Decompression removes what is pressing on the cord. Tumour cells remain in the bone around it, and the cancer elsewhere is untouched. Radiotherapy and medicines are what keep it in check afterwards.
"If he cannot walk now, surgery will make him walk again."
Sometimes, if the weakness came on recently and the pressure is relieved quickly. If the legs have not moved for many days, recovery is much less likely. The surgeon can give a fairer estimate after examining him.
"Touching the spine with cancer in it will spread it."
Surgery does not send the cancer travelling. The cancer is already in the spine, and leaving it pressing on the cord is what causes lasting harm.
"She will need to lie in bed for months afterwards."
Getting up early is part of recovery. Because the spine is held with screws and rods, most people sit and stand with a physiotherapist within days. Long bed rest brings clots, chest infections and pressure sores.
Take this with you
What should you ask the surgeon before agreeing?
- Which approach are you planning, and why that one?
- Will screws and rods be needed, and how many levels?
- What would happen if we chose radiotherapy alone?
- Which risks matter most in my situation?
- When will radiotherapy start after the operation?
- Who will do the operation, and who looks after me afterwards?
Questions we are asked
Common questions about decompression surgery
How soon after the diagnosis is the operation done?
When the cord is under pressure, quickly. Most teams aim to operate within a day or two of the MRI, because nerves recover better the sooner pressure is relieved. Steroids are usually started before that to reduce swelling while the operation is arranged.
How long will I be in hospital?
It varies more than most operations, because it depends on how strong the legs are, bladder control and pain. Some people go home within a week or so. Others move to a rehabilitation stay first. Ask your team for a realistic estimate for your situation.
Will the back pain go away after surgery?
Pain from a collapsing, unstable bone often eases soon after the spine is fixed. There will be wound pain for a while, which is treated with regular painkillers. Nerve pain down the legs or around the chest can take longer to settle and may need different medicines.
Will I need a brace afterwards?
Some people do, particularly after surgery in the neck or where the bone is very soft. Many do not, because the screws and rods do the holding. Your surgeon will tell you before the operation and the physiotherapist will fit it.
Can chemotherapy continue around the operation?
Usually it is paused for a time around surgery, because many cancer medicines slow wound healing and lower blood counts. The surgeon and your medical oncologist agree the timing between them. Do not stop or restart any medicine on your own.
What if the tumour grows back at the same place?
It can happen, which is why radiotherapy follows surgery and why follow-up scans are arranged. If new pain or weakness appears, tell the team the same day. Further radiotherapy or, less often, another operation may be possible.
Is my father too old for this operation?
Age alone does not decide it. How active he was before, his heart and lung health, and how the cancer is behaving matter more. The anaesthetist's assessment is part of the decision, and you can ask to hear their view directly.
Is decompression surgery covered by Aarogyasri or insurance?
Often, as part of an approved cancer treatment plan. Aarogyasri, CGHS, ECHS and EHS are accepted at CION, and most cashless insurers are empanelled. Implants may be billed separately, so ask for a written estimate that includes them, and call the helpline to check your cover.
