Thermotherapy, or therapy by induced localised hyperthermia, may be used as a cancer treatment to kill or weaken tumor cells, with limited effects on healthy cells. Tumor cells, with a disorganized and compact vascular structure, have difficulty dissipating heat. Hyperthermia may therefore cause cancerous cells to undergo apoptosis in direct response to applied heat, while healthy cells can more easily maintain a normal temperature. Even if the cancerous cells don't die outright, they may become… (More on Thermotherapy)
