Local hyperthermia is heat therapy. It has been used for several centuries as a treatment for various diseases, including cancer.
One article (1) looked at local hyperthermia and its treatment of cancer. According to the National Cancer Institute (NCI), researchers believe that heat may decrease the growth of cancer along with chemotherapy and radiation therapy. In local hypothermia treatments, a small area of the body is used to treat cancer, rather than treating cancer with chemotherapy and radiation therapy alone.
The article indicated that local hyperthermia is used with slim heated wire probes, which are hollow tubes filled with lukewarm water. Some of the patient’s blood is taken from the body, heated, and then pumped back into the area of the body to be heated. The process is known as perfusion. This is different from whole body therapy, in which the entire body is heated at the same time.
