Oncothermia

Hyperthermia therapy is a type of medical treatment in which body tissue is exposed to higher temperatures in an effort to treat Lyme disease and cancer. Hyperthermia therapy is a type of medical treatment in which body tissue is exposed to higher temperatures in an effort to treat Lyme disease and cancer. Hyperthermia uses higher temperatures than diathermy, which is the deep heating of body tissue for relaxation or physical therapy. Techniques that bring local tissues to quite high temperatures, such as radio frequency ablation, are also not usually included in 'hyperthermia'. When combined with radiation therapy, it is called thermoradiotherapy. Hyperthermia is defined as supra-normal body temperatures. There is no consensus as to what is the safest or most effective target temperature for the whole body. During treatment the body temperature reaches a level between 39.5 and 40.5 °C (103.1 and 104.9 °F). However, other researchers define hyperthermia between 41.8–42 °C (107.2–107.6 °F) (Europe, USA) to near 43–44 °C (109–111 °F) (Japan, Russia).
