What is hyperthermia in cancer treatment?
Hyperthermia is heat therapy. Heat has been used for hundreds of years as cancer therapy. Scientists believe that heat may help shrink tumors by damaging cells or depriving them of what they need to live. It may also make the cancer cells more sensitive to other cancer treatments like radiation and chemotherapy. Research studies are underway to determine the use and effectiveness of hyperthermia in cancer treatment. It's used at some cancer treatment centers along with chemotherapy or radiation to treat advanced cancer. It's not widely available.
How is it used?
Heat can be applied to a very small area, to an organ or limb, or to the whole body. Hyperthermia is often used with chemotherapy, radiation therapy, and other cancer treatments. These are the types of hyperthermia:
|
Type of hyperthermia |
Treatment area |
Method of application |
|
Local hyperthermia |
Treatment area includes a tumor or other small area. |
|
|
Regional hyperthermia |
An organ or a limb is treated. |
|
|
Whole-body hyperthermia |
The whole body is treated. |

Are there any side effects?
Side effects may include skin discomfort or local pain. Hyperthermia can also cause blisters and sometimes burns. But these generally heal quickly. Local hyperthermia can cause pain at the site, infection, blood clots, burns, and damage to the muscles, skin, and nerves in the treated area. Whole-body hyperthermia can cause diarrhea, nausea, and vomiting. Improved technology, research, and treatment experience have resulted in fewer side effects. Most side effects people have are short-term and not serious.

Laser Therapy for Cancer Treatment
Laser therapy can be used to cut a very tiny area to remove very small cancers without damaging surrounding tissue. Lasers also are used to apply heat to tumors to shrink them. They are sometimes used with medicines that are activated by laser light to kill cancer cells.
Preparing for Cancer Treatment
The first step in preparing for your cancer treatment is to find an oncologist and treatment center. Ask your general or primary healthcare provider for a referral or contact government and professional medical organizations, such as your state's health department, the National Cancer Institute, or the American Medical Association, for information on cancer specialists and treatment centers in your area.
