Why surgeon and hospital volume matter | CION Cancer Clinics
For most major cancer operations, patients treated by a surgeon and a hospital that do that operation often have fewer serious complications and are safer in the weeks afterwards than patients treated where it is done rarely. Surgeon volume and hospital volume are separate questions, and both can be asked plainly. This page explains where the effect is largest, what volume cannot tell you, and how to ask. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
Does it matter how often a surgeon does an operation?
Yes. For most major cancer operations, patients treated by a surgeon and a hospital that do that operation often have fewer serious complications and are less likely to die in the weeks after surgery than patients treated where it is done rarely. This has been shown across many countries and many cancers.
Why practice changes the result
A cancer operation is a long series of small decisions. How much to take. Which lymph nodes (the small glands that drain the area) to remove. When a bleed is small enough to leave and when it is not. A surgeon who has faced each of those decisions hundreds of times makes them faster and more safely than one who has faced them a handful of times. The same is true of the ward and ICU team.
Hospital volume and surgeon volume are different things
Surgeon volume is how often your surgeon personally does this operation. Hospital volume is how often the whole building does it. Both matter. A skilled surgeon in a hospital that rarely sees this operation is working with a ward and an ICU that do not know what to watch for. Ask about both, separately.
Volume is not the only thing that matters. It is the one thing that is easy to ask about and hard to fake.Not all operations are equal
For which operations does volume matter most?
The effect is strongest where the operation is long, complex, and where things can go wrong quietly in the days afterwards.
Pancreas, food pipe and stomach
These are the operations where the volume effect is largest. The joins made inside the body can leak, and spotting a leak early depends on a team that has seen one before. Ask this question hardest here.
Ask about
- How many a year, surgeon and hospital
- Who watches for a leak at night
Liver, rectum and lung
Large operations where bleeding, the quality of the margin and the number of lymph nodes removed all depend on experience. The difference between a careful and a rushed operation may only show up in the pathology report weeks later.
Head, neck and thyroid
Here the risk is less about dying and more about what you keep. Your voice, your swallowing, the nerves in your face. Surgeons who do these operations often are more likely to preserve them.
Breast and skin
The volume effect is smaller for these because the operations are shorter and the recovery is simpler. Volume still matters for getting the margin right and for the look of the result, but the overnight risk is lower.
Even here, a surgeon who does breast surgery every week is a fair thing to ask for.Not sure whether this applies to you?
Ask an oncologistWords you will hear
What do the words used about volume actually mean?
- High-volume centre
- A hospital that does a particular operation many times a year. It is different for each operation, so ask for the figure, not the label.
- Complication rate
- How often something goes wrong after the operation, from a wound infection to a leak that needs a second operation. A surgeon should be able to tell you the common ones for your operation.
- Failure to rescue
- A complication happens in every hospital. What differs is whether it is noticed and treated in time. This is where the ICU and the overnight team matter as much as the surgeon.
- Margin
- The rim of normal tissue around what was removed. A clear margin means no cancer cells at the edge. Experienced surgeons get clear margins more often.
- Lymph node yield
- How many glands were removed and examined. Too few and the stage (how far the cancer has spread) cannot be worked out properly.
- Tumour board
- The meeting where surgical, medical and radiation oncologists look at a case together. A sign of a team, not one person, planning your care.

Commonly believed
Four things families tell us, and what is actually true
"A big hospital must be a high-volume hospital."
Not for your operation. A large hospital may do thousands of heart operations and very few pancreatic ones. Volume is counted operation by operation. Ask about yours, not about the hospital's size or its total number of beds.
"He has been a surgeon for thirty years, so he must be experienced."
Years in practice and volume in this operation are different. A surgeon who has spent decades on hernias and gall bladders may have done very few cancer operations of the type you need. Ask how many of these, and how recently.
"If the surgeon is good, the hospital does not matter."
The surgeon is in the theatre for a few hours. The ward and ICU look after you for days. Most deaths after major surgery come from a complication that was noticed too late, and that is a hospital problem, not a surgeon problem.
"Asking about numbers will annoy the surgeon."
Surgeons who do an operation often are usually pleased to be asked, because the answer works in their favour. The surgeon who is annoyed by the question is more often the one who does not like the answer.
Being straight with you
How do you ask about volume, and what can this page not tell you?
Ask two plain questions. "How many of this exact operation do you do in a year?" and "How many does this hospital do?" Then ask what the common complications are and who watches for them overnight. Write the answers down.
What a good answer sounds like
A specific number, given without hesitation, and a clear account of what can go wrong. A surgeon who answers with the hospital's reputation has not answered the question. Ask it again, politely.
Who this advice does not suit
If your operation is urgent, for example a bowel that is blocked or a tumour that is bleeding, there may be no time to shop for volume. In that case the nearest safe hospital is the right one, and the question to ask is whether the cancer surgery itself can be planned separately, later, with a specialist team.
What this page cannot tell you
It cannot tell you what number counts as enough for your operation, because that differs for each cancer and each procedure. It cannot promise a good result in your case, and it cannot tell you whether you need surgery at all. Those questions belong to the team treating you and the tumour board that looks at your scans.
We do not publish rankings of named surgeons or hospitals, and we would be wary of any site that does.Questions we are asked
Common questions about surgeon and hospital volume
What number of operations a year is enough?
There is no single figure, and it differs by operation. For rare, complex operations such as those on the pancreas or food pipe, a surgeon doing them every few weeks is in a different position from one doing them a few times a year. Ask for the figure and ask how it compares with a specialist cancer centre.
How do I find out a surgeon's volume if they will not say?
Ask the hospital's patient services desk how many of this operation the hospital did last year. Ask your medical oncologist or family doctor, who often know. If nobody will give a number, treat that as your answer.
Is a government cancer hospital high volume?
Often, yes. Large government cancer centres see very many patients and their surgeons may do particular operations more often than anyone in the private sector. The trade-off is usually waiting time and crowding, not surgical experience.
Does a surgeon's volume matter for a small operation like a lump removal?
Less, but not nothing. For a short operation with a simple recovery, the main risk is a margin that is not clear and a second operation to fix it. A surgeon who does that operation every week gets it right more often. The overnight risk is low, so hospital volume matters less here.
My surgeon is high volume but the hospital is small. Is that a problem?
It can be, for a major operation. Ask what happens if there is a leak or a bleed at night: is there a doctor in the building, is the ICU staffed, is there blood on site. A small hospital with all three can be safe. A small hospital without them is the situation the volume evidence warns about.
Should I travel to Hyderabad for a higher-volume surgeon?
For a major operation, often yes, if travel is possible for you. For a smaller operation, a nearer surgeon with the right training may be the better choice, because the follow-up visits for wounds, drains and the pathology report are easier. Ask whether surgery here and follow-up at home can be arranged.
Does the volume of the anaesthetist matter too?
Yes, though it is rarely asked about. Long cancer operations need an anaesthetist used to keeping a patient stable for many hours and used to the particular problems of that operation. Ask whether the anaesthetist works with this surgeon regularly.
Will CION tell me its own numbers?
Ask, and the surgeon seeing you will answer for the operation being discussed. We do not compare ourselves with named hospitals or surgeons. Every case at CION goes to a tumour board before an operation is booked, and you are welcome to ask what was discussed.
