The term hyperthermia broadly refers to either an abnormally high fever or the treatment of a disease by the induction of fever, as by the injection of a foreign protein or the application of heat [1]. Hyperthermia as a method of treating cancer has a long history. Many Greek and Roman physicians thought that if they could simply control body temperature they could cure all diseases. This included cancer, because the pathology of tumor development had been described in the Greek literature [2].
