Surgery is when a surgeon removes all or part of the cancer. It can be used to treat many types of cancer.
Surgery is a medical procedure to examine, remove or repair tissue. For example, it can be used to diagnose or remove cancer. We have more information on when surgery is used.
The type of surgery you have, and how long you stay in hospital for, depends on your situation. Your healthcare team will talk to you about this. They will explain:
- how you can prepare for the surgery
- the possible side effects and complications of the surgery
- how you recover from the surgery.
They will give you written information explaining this before you agree (consent) to have treatment.
You may also find it helpful to read more about type of cancer you have. This includes specific information on the types of surgery you may have.

You may have other treatments in combination with surgery. This could be:
- before surgery, to shrink the cancer and make surgery possible – this is called neoadjuvant treatment
- before surgery, to reduce the amount of surgery needed
- after surgery, to get rid of any remaining cancer cells and reduce the risk of cancer coming back – this is called adjuvant treatment.
You can read more about this in our information about the type of cancer you have.
There are different ways of doing cancer surgery. The main types include:
Open surgery is when the surgeon makes a single, often large, cut. Sometimes they make more than one cut. For example, in breast surgery, they may make another cut in the armpit area (axilla) so that they can remove the lymph nodes.
Keyhole surgery (laparoscopic)
In keyhole surgery, the surgeon makes several small cuts instead of a single large cut. This leaves a much smaller wound, so you usually recover faster.
The surgeon puts a thin tube with a light and camera on the end through the small cuts in the skin. This tube is called a laparoscope. It allows the surgeon to examine the area and remove tissue through the cuts.
You may also find it helpful to read more about the type of cancer you have. This includes specific information on the tests or types of surgery you may have.
Robotic surgery is when keyhole surgery is helped by a machine. Instead of the surgeon holding the laparoscope and the surgical equipment, these are attached to robotic arms. The surgeon controls the robotic arms, which can move very precisely.
This is very specialised surgery and only available in some hospitals in the UK.
Sometimes tissue can be removed without making any cuts through the skin. The doctor uses a thin, flexible tube with a light and camera on the end to examine areas inside the body. This tube is called an endoscope. The surgeon passes the endoscope through an opening in the body, such as the mouth or back passage (rectum).
Instruments can be passed through the endoscope to remove a sample of tissue (biopsy), or sometimes pre-cancerous cells or small cancers.
Sometimes an endoscope is used to give treatments that destroy pre-cancerous cells or cancer cells. These include light beams (laser therapy), electricity (electrosurgery), freezing (cryosurgery), and heat (radiofrequency ablation).
Your healthcare team will plan your operation carefully. They will explain about the surgery, the possible side effects, and what to expect.
You may have a pre-assessment appointment 1 to 2 weeks before the surgery. This is usually with a nurse, who will do some tests and checks before your surgery. They will also help you prepare for your surgery and you can ask them any questions you may have.
We have more information about preparing for surgery.
In most hospitals, a team of specialists will agree on a plan of treatment for you. This is called a multidisciplinary team (MDT). It will include your surgeon, nurses and other types of healthcare professionals. Who you meet will depend on:
- the type of cancer you have
- the operation you are having
- if you are having any other treatments.
We have more information about your multidisciplinary team (MDT) for surgery.
When you wake up after surgery
Your doctor or nurse will explain what to expect when you wake up after surgery. If it is a big operation, you may wake up in intensive care or a high dependency recovery unit. You usually move back to the ward within a day or so.
How you feel when you wake up will depend on what kind of surgery you had. You may have the following:
- side effects, such as pain, or feeling sick. Tell your nurse if this happens and they can give you something to help.
- a drip of fluids into a vein in your arm
- a tube (drain) put into your wound to help remove any extra fluid. Your doctor or nurse will tell you about this beforehand.
How long you are in hospital will depend on what type of surgery you had. You are usually encouraged to get up and move around as soon as you feel able to. This can help with recovery.
Your nurse will look after your wound while you are in hospital. They will explain how to look after it at home. Some people may need their dressings changed by a community nurses or their practice nurse.
Complications of surgery
Your doctor or nurse will explain about any complications to look out for. If you feel unwell or have any problems while you are at home, contact the hospital straight away on the number they give you.
Follow-up after your operation
You usually see your surgeon or clinical nurse specialist (CNS) a few weeks after your surgery. They will check the scar and make sure everything is healing properly. They will also give you advice about how soon you can get back to work, travel or drive again.
Your follow-up will depend on:
- the type of cancer you have
- what kind of operation you had
- if you are having any other treatments.
It may be with your surgeon or sometimes with your nurse. They will explain how often you will have follow-up appointments.
