[Treatment of superficial cancerous tumors by hyperthermia induced by ultrasonics or microwaves]

Abstract

Results of treating superficial human cancerous tumors by ultrasound (1-3 MHz) or microwave (434 MHz) hyperthermia, alone or combined with radiotherapy or chemotherapy are presented according to the heating method. The comparison of in vivo thermal distributions obtained at depth with these two techniques could partially explain their different therapeutic efficiency.
