Because most tumors lack a fully developed network of blood vessels, blood flows much more sluggishly through them than through normal tissue, and heat is not so quickly transported out. Thus tumors are far more susceptible to heat. At high enough temperatures, the malignant cells are killed...

LeVeen also agrees with the authors of an accompanying editorial in JAMA, Drs. Joan M. Bull and Paul B. Chretien of the National Cancer Institute, who urge additional tests on patients-with special attention directed toward any adverse side effects-before wide-scale application of heat therapy in cancer treatment. Such trials are now being planned at several VA hospitals...

It came from the same doctors who did more than anyone else to create the massive U.S. methadone program, which is currently treating some 80,000 addicts. In a special report to JAMA, Drs. Vincent P.
