Kidney Cancer





Radiation Therapy

Radiation therapy, also called radiotherapy, uses high-energy rays to kill cancer cells. Doctors sometimes use radiation therapy to relieve pain (palliative therapy) when kidney cancer has spread to the bone.

Radiation therapy for kidney cancer involves external radiation, which comes from radioactive material outside the body. A machine aims the rays at a specific area of the body. Most often, treatment is given on an outpatient basis in a hospital or clinic five days a week for several weeks. This schedule helps protect normal tissue by spreading out the total dose of radiation. You don't need to stay in the hospital for radiation therapy, and you're not radioactive during or after treatment.

Biological Therapy

Biological therapy, also called immunotherapy, is a form of treatment that uses the body's natural ability or immune system, to fight cancer. Interleukin-2 and interferon are types of biological therapy used to treat advanced kidney cancer.

Clinical trials continue to examine better ways to use biological therapy while reducing the side effects patients may experience. Many people receiving biological therapy stay in the hospital during treatment so that these side effects can be monitored.


Chemotherapy is the use of drugs to kill cancer cells. Although useful in the treatment of many other cancers, chemotherapy has shown only limited effectiveness against kidney cancer. Researchers continue to study new drugs and new drug combinations that may prove to be more useful.

Hormone Therapy

Hormone therapy is used in a small number of patients with advanced kidney cancer. Some kidney cancers may be treated with hormones to try to control the growth of cancer cells. More often, it is used as palliative therapy or therapy to relieve pain.
