Surgery for lung metastases from another cancer | CION Cancer Clinics
Sometimes, yes. When a cancer that began elsewhere has sent a small number of deposits to the lung, an operation to remove them is called a lung metastasectomy. It is offered when the original cancer is controlled, the spread is only in the lung, every deposit can be removed, and you are fit for a chest operation. This page explains which cancers it is used for, what happens, and what it cannot do. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Can lung metastases from another cancer be removed by surgery?
Sometimes, yes. When a cancer that started elsewhere, such as the bowel or a bone, has sent a small number of deposits to the lung, an operation to remove them is called a lung metastasectomy. It is offered to a specific group of people.
What "metastases" means on your report
A metastasis (plural metastases) is a deposit of the original cancer that has travelled through the blood or lymph and settled in another organ. Lung deposits from a bowel cancer are still bowel cancer cells, not lung cancer. The treatment follows the original cancer, and so does the decision about surgery.
The four conditions the team looks for
The original cancer is under control or removed. Scans show no spread anywhere except the lung. Every lung deposit can be removed while leaving enough lung to breathe on. And you are fit enough for a chest operation. When all four hold, surgery is discussed as one option. When one is missing, the team usually looks to other treatments first.
This page describes what is weighed. It cannot tell you whether surgery is right for your own situation. That is a tumour board decision made with your scans in front of them.Where it is used
Which cancers most often lead to lung metastasectomy?
The lung is a common place for cancers to spread to, but only some of them are treated with surgery when they do.
Bowel (colorectal) cancer
The commonest reason for this operation. Bowel cancer often spreads to the liver and lung in a limited way, and removing those deposits after the bowel tumour has been dealt with is an established part of treatment.
Sarcomas of bone and soft tissue
These cancers spread to the lung more than anywhere else, and often to the lung alone. Surgery for lung deposits has a long history here, and some people have more than one operation over the years.
Kidney cancer
Kidney cancers can appear in the lung years after the kidney was removed. Where the deposits are few and slow-growing, surgery is one of the options alongside targeted tablets and immunotherapy.
Germ cell tumours and others
Testicular and other germ cell cancers may need surgery to remove what is left in the lung after chemotherapy. Melanoma, head and neck cancers and some breast cancers are considered case by case.
Usually not treated this way
- Cancers with spread in several organs
- Cancers that respond well to drug treatment alone
Not sure whether this applies to you?
Ask an oncologistBefore it is offered
What does the team check before suggesting surgery?
- That the original cancer has been removed or is fully controlled
- A PET-CT or full-body scan showing no deposits outside the lung
- How many deposits there are, and whether all of them can be reached
- How long the gap was between the first cancer and the lung deposits appearing
- Breathing tests showing enough lung would be left afterwards
- Whether radiotherapy, ablation or drug treatment would do the same job with less risk
In theatre
What does the operation usually involve?
Small pieces, not whole lobes
Most deposits sit near the surface of the lung, so the surgeon removes each one with a rim of healthy tissue around it. This is a wedge resection. A whole lobe is taken only when a deposit sits deep or near a main airway.
Keyhole or open
Keyhole surgery suits a small number of deposits that the scan shows clearly. An open cut lets the surgeon feel the whole lung by hand and find tiny deposits the scan missed. Which is chosen depends on the cancer type and the scan.
One side or both
When both lungs have deposits, they are usually operated on in two sittings a few weeks apart, so you are never recovering from both sides at once. Occasionally both are done in one operation through the front of the chest.
Drain, walking, home
A chest drain stays in until the lung has sealed. Because the pieces removed are small, most people are walking the next day and home within days, with a sore chest that eases over the following weeks.

Being straight with you
What can surgery for lung spread not do?
It removes the deposits that can be seen. It does not treat cancer cells too small to show on any scan, and it does not change the cancer that produced them. New deposits can appear later, and the team will say so plainly before you decide.
The alternatives on the table
Focused radiotherapy (SBRT) can treat a small deposit in a few outpatient sessions without an anaesthetic. Ablation destroys a deposit with heat or cold through a needle. Chemotherapy, targeted tablets and immunotherapy treat the whole body rather than one spot. The tumour board weighs all of them together.
Who this operation does not suit
People whose original cancer is still active. People with deposits in the liver, bones or brain as well as the lung, unless those can be treated too. People whose lungs could not spare the tissue. And people whose cancer is of a type that responds well to drugs alone, where an operation would add risk without adding benefit.
No page can say how much time or benefit this surgery will give you. Ask your oncologist what the aim of the operation is in your case, and what would happen without it.Commonly believed
What do families believe about spread to the lung, and what is true?
"Spread to the lung means nothing more can be done."
For some cancers, a small amount of spread to the lung is treated actively, with surgery, focused radiotherapy or drug treatment, and people live with it for years. Ask which group your cancer falls into before assuming the worst.
"Opening the chest will make the cancer spread faster."
There is no evidence that an operation spreads a cancer. What does happen is that deposits too small to see may grow later, whether or not surgery was done. The team judges that risk from the scans and the gap since the first cancer.
"If the surgeon removes it all, the cancer is finished."
Removing every visible deposit is the aim, and it is often achieved. It is not the same as removing every cancer cell. Follow-up scans continue precisely because new deposits can appear, and catching them early keeps the options open.
"A second lung operation is too much for anyone."
People with sarcoma in particular sometimes have two or three lung operations over the years, each removing small pieces. Whether a repeat is sensible depends on lung function and on how the cancer has behaved, not on a fixed limit.
On your report
What do the words on the scan report and referral mean?
- Metastasectomy
- An operation to remove a metastasis. "Pulmonary metastasectomy" means removing deposits from the lung.
- Oligometastatic
- A cancer that has spread, but only to a small number of spots. This is the situation in which surgery or focused radiotherapy for spread is considered.
- Disease-free interval
- The time between treatment of the original cancer and the lung deposits appearing. A longer gap generally suggests a slower cancer, which weighs in favour of local treatment.
- Wedge resection
- Removing a small, wedge-shaped piece of lung containing the deposit and a rim of healthy tissue. The usual operation for a surface deposit.
- Ablation
- Destroying a deposit with heat, cold or microwaves through a needle placed under scan guidance, without an operation.
Questions we are asked
Common questions about surgery for lung metastases
How many lung deposits can be removed in one operation?
There is no fixed number. What limits it is how much healthy lung would be lost, and whether the deposits can all be reached. Several small surface deposits may be easier to remove than one deep one. Your surgeon will look at the scan and tell you what is realistic.
Is a lung deposit from bowel cancer treated as lung cancer?
No. The cells are bowel cancer cells living in the lung, and the drug treatments follow the bowel cancer. This is why the oncologist may ask for a biopsy of the lung spot if there is any doubt: a new lung cancer and a bowel cancer deposit are treated quite differently.
Would radiotherapy do the same job without an operation?
For a single small deposit, focused radiotherapy is often a real alternative and is given as an outpatient. Surgery has the advantage of removing tissue for the laboratory and of letting the surgeon check the rest of the lung. The tumour board weighs the two for each person.
Will he need chemotherapy as well?
Often, before or after the operation, depending on the cancer type. For bowel cancer it is common; for sarcoma it depends on the subtype. The operation and the drug treatment are planned together rather than one at a time, so ask the oncologist for the whole sequence.
What if the scan shows new spots after the operation?
It is discussed again at the tumour board. The options may include another operation, focused radiotherapy, ablation or a change in drug treatment. New spots are not a sign that the first operation failed; they are why follow-up scans continue.
How much lung will he lose?
Usually very little, because most deposits are removed as small wedges rather than whole lobes. Breathing tests are done beforehand to be sure, and most people notice little difference once the chest has healed.
Will the operation get rid of the cancer for good?
The aim is to remove all visible cancer, and for some people the cancer does not return. No one can promise that beforehand, and this page will not. Ask your oncologist what the aim is in your case and what they would expect with and without the operation.
Does Aarogyasri or insurance cover it?
Lung surgery for cancer is generally covered under Aarogyasri, CGHS, ECHS and EHS, and most cashless insurers are empanelled, but cover for surgery on spread can need extra approval. Call the helpline with your card details and we will check before you travel.
