Surgery to treat cancer
Surgery means cutting away tissue from the body during an operation. You might have surgery as an inpatient or an outpatient. It usually means having either a local anaesthetic or general anaesthetic.
You might have surgery for any of the following reasons
- To diagnose cancer – a small sample of tissue is taken to examine under a microscope
- As a treatment to cure cancer
- To rebuild (reconstruct) a part of your body
- To prevent or reduce the risk of cancer
- To control symptoms or extend life
- As part of other treatments, such as having a central line put in
When is surgery used for cancer?
Whether surgery is a treatment option for you depends on your type of cancer, how big the cancer is, and where it is in the body, as well as your general health.
Surgery is likely to cure many small early stage cancers and might be the only treatment you need. For some cancers you have other treatments such as chemotherapy or radiotherapy before or afterwards. These treatments might shrink a tumour, so it's easier to remove or may lower the chance of the cancer coming back.
Surgery is not usually used to treat cancers involving the blood system (such as leukaemias and some types of lymphoma). It is also not usually an option if your cancer is advanced, or near a blood vessel or other delicate tissue. In this situation it may cause too much damage.
If you are going to have an operation for cancer, your doctor explains what it involves and tells you about any possible after effects.

You may have surgery
To diagnose cancer a surgeon may remove a small piece of tissue. This is called a biopsy. If the biopsy contains cancer cells, it might show what type of cancer it is and how slowly, or quickly it may grow.
Surgery is one of the main treatments for cancer. It might be the only treatment you need.
Surgery is a local treatment – it only treats the part of the body operated on. So it may cure cancer that is completely contained in one area and hasn't spread. Usually, the earlier a cancer is found the easier it is to remove it.
Your surgeon removes the tumour and some normal tissue from around the cancer (known as a clear margin). They might also remove the lymph nodes nearest to the cancer, in case they contain cancer cells.
The surgeon sends all the tissue that they remove to a laboratory for examination under a microscope. This gives more information about the cancer. It helps doctors to decide whether you need any further treatment to reduce the risk of the cancer coming back. This is called adjuvant treatment and is most often chemotherapy or radiotherapy.
Some people have treatment before surgery to help shrink a cancer and make it easier to remove. This is called neo adjuvant treatment.
During an operation, surgeons sometimes find that a cancer has spread further than they expected. When this happens, the operation might take longer than planned, or may have to be stopped altogether.
If cancer has spread to another part of the body, surgery can't usually cure it. But with some types of cancer, surgery can help people to live for a long time and may sometimes lead to a cure. When a cancer has spread, it might be better to have a treatment that works throughout your body, such as chemotherapy, biological therapy or hormone therapy. Radiotherapy can control symptoms caused by areas of cancer elsewhere in the body.
If you have part of your body removed, it might be possible to have reconstructive surgery. The part of the body is recreated using other body tissues or a false body part (prosthesis). For example, after removal of a breast (mastectomy) it might be possible to have breast reconstruction. Or if you have your bladder removed it may be possible to make a new bladder.
If you are at high risk of a particular type of cancer, you might be able to have surgery to reduce that risk. For example, people who have a rare inherited condition called Familial Adenomatous Polyposis (FAP) have an increased risk of bowel cancer. So they might choose to have surgery to remove their large bowel. Women who have a high risk of breast cancer may choose to have their breasts removed.
You will be given advice to help you make the decision to have surgery or not.
People might have surgery to relieve symptoms if their cancers can't be completely removed, or cured with other treatments. For example, cancers in the abdomen can sometimes block the bowel and cause sickness and pain. An operation to remove or bypass the blockage can relieve these symptoms.
Surgery might also help to control pain by removing cancer that is pressing on a body organ or nerve.
Occasionally it is possible to remove cancer that has spread into nearby organs or to another part of the body. For example, people who have kidney cancer that has spread to the lung might be able to have surgery to remove the lung tumours. The surgery is unlikely to cure the cancer but can reduce symptoms and may help some people to live longer.
Some operations are done so that you can have other treatments for cancer. For example, you might have a small operation to put a thin tube called a central line into a main vein in your chest. The tube stays in throughout your treatment. It makes having chemotherapy or biological therapy easier because you don’t need to have a needle put into a vein each time you have treatment. You can also have blood taken from the tube.
Some operations are done to help doctors give treatments to areas inside the body. The surgery allows surgeons to give treatments such as radiofrequency ablation or cryotherapy.
For some cancers, surgery is the only treatment you may need. It is likely to cure small, early stage cancers that haven't spread to other parts of the body.
Whether surgery is an option depends on
- the type of cancer you have
- the stage and position of your cancer
- your general health
If your cancer has spread or is at an advanced stage, surgery might not be the best treatment for you. It may be better to have a treatment that reaches all parts of your body, such as chemotherapy, biological therapy or hormone therapy. Radiotherapy might be used to shrink tumours and help to control symptoms.
Surgery is not used for some types of cancer of the blood system (leukaemia). It is also not used for some types of cancer of the lymphatic system (lymphoma), if the cancer cells are spread throughout the body. If the cancer is in a lot of areas, surgery won’t get rid of it all.
Sometimes surgery is not possible because of the position of the tumour – for example, if the tumour is near a blood vessel or other delicate tissue. In this situation, surgery might cause too much damage to the surrounding tissue. Other treatments may be used instead if your doctor thinks it might help.
