Surgery is the main treatment for kidney cancer that has not spread to other parts of the body.
Stage 1 and 2 kidney cancers are contained within the kidney and are often cured with surgery.
Stage 3 cancers have spread into a nearby lymph node, the adrenal gland or the major vein leading to the kidney. They are called locally advanced kidney cancers and can sometimes be cured if it is possible to remove all the cancer.
If the cancer is small, surgeons usually try to just remove the tumour and leave behind as much of the kidney as possible. They call this partial nephrectomy or nephron sparing surgery. The nephron is the part of the kidney that filters the blood to make urine.
If the cancer is larger than 7cm or so your surgeon may remove the whole kidney (a complete nephrectomy). If the cancer has spread into nearby lymph nodes, the adrenal gland, or the vein leading to the kidney, your surgeon will remove them during the surgery.
If there is a risk of the cancer coming back in the kidney area after surgery your doctor may recommend radiotherapy to the area. There is information about radiotherapy in this section.

Monitoring the cancer
Some kidney cancers are found by chance when patients have scans for other reasons. Many of these tumours are small and some may not cause any problems for a long time even without treatment. Small kidney cancers are very unlikely to spread into surrounding tissue or elsewhere in the body.
So if you have a kidney cancer that is less than 3cm and are older or unwell, your doctor may advise having no treatment at first. But they will watch the cancer carefully. You have regular scans to see if the cancer grows. Doctors call this active surveillance.
There is information about monitoring kidney cancer in this section. If the cancer starts to grow you usually have treatment to destroy or remove it.
If you can’t have surgery
It may not be possible for you to have surgery if you have other medical problems. In this case, if you have a small cancer the doctor might use freezing therapy (cryotherapy) or radiowave treatment (radiofrequency ablation).
Your doctor may also suggest these treatments if you have a rare inherited form of kidney cancer and have more than 1 tumour, or if you have cancer affecting both kidneys.
If you have a larger cancer, or the cancer is causing symptoms such as pain or bleeding, your doctor may suggest radiotherapy to shrink the cancer and reduce symptoms. Or they may suggest a treatment called arterial embolisation that blocks the blood supply to the kidney.
There is information about arterial embolisation in the section on surgery for kidney cancer.
Freezing therapy (cryotherapy)
Cryotherapy is also called cryosurgery or cryoablation. It is a way of killing cancer cells by freezing them. For kidney cancer a surgeon puts a cryotherapy probe into the area of cancer in the kidney. They can do this with keyhole surgery through the skin or by making a larger cut (incision in the skin). You have this treatment under local anaesthetic or general anaesthetic.
There is information about cryotherapy for kidney cancer in this section.
Radio wave treatment (RFA)
Radio wave treatment uses high frequency radio waves to heat the cancer cells. It is called percutaneous radiofrequency ablation (RFA). Your surgeon puts one or more needle electrodes through the skin into the tumour. They use images (like ultrasound) to guide the needles into place. When the electrodes are in place a radiofrequency electrical current passes through them to destroy the cancer cells.
There is information about radiofrequency ablation for kidney cancer in this section.
Radiotherapy uses high energy X-rays to kill cancer cells. It is not used often for cancer of the kidney because kidney cancer cells are not as sensitive to radiation as some other types of cancer. But your doctor may suggest radiotherapy to help control the symptoms of an early cancer if you are not well enough to have other treatments.

Biological therapies are a group of treatments that interfere with the way cells work. They can be used to boost the body’s immun system to help kill cancer cells.
We have detailed information on biological therapies for kidney cancer.
If kidney cancer comes back
In some people kidney cancer comes back in the area of the kidney after surgery. In this situation your doctor may recommend surgery to remove the cancer or the whole kidney again. This further surgery can get rid of the cancer completely for some people. Your doctor may recommend treatment with biological therapies such as sunitinib (Sutent) or sorafenib (Nexavar) to try to reduce the chance of the cancer coming back again.
There is information about biological therapy for kidney cancer in this section.
If the cancer comes back in another part of the body it is called advanced or metastatic kidney cancer. Your treatment will depend on where the cancer is. You usually have surgery if it is possible to remove the cancer. If the cancer is in an area where surgery is not possible you usually have biological therapy treatments to stop the cancer from growing and keep it under control. These treatments can control the cancer for months or sometimes years.
You can read about these treatments on the page about treating advanced kidney cancer.
Planning your treatment
Your doctors plan your treatment by taking into account a number of factors, including
- Your general health and fitness
- The size of your cancer and where it is in the kidney
- Whether the cancer has spread into lymph nodes close to the kidney
You will be under the care of a multi disciplinary team. This is a team of health professionals who work together to discuss your case and how best to manage your treatment and care. The team includes
- Doctors, including a specialist surgeon (urologist), a cancer specialist (oncologist), a specialist in scans and X-rays (radiologist) and a specialist in analysing tissue samples (pathologist)
- A specialist nurse for information and support
- Symptom control specialists
- Physiotherapists and occupational therapists
- Psychologists and counsellors
