Abstract
The instant invention is directed to a noninvasive tumor treatment modality which results in a reduction of tumor mass and may lead to complete eradication of a tumor. The inventive method comprises localized magnetically-coupled, RF-induced hyperthermia mediated by a material which is non-toxic to and, preferably, compatible with animal tissue and has incorporated therewithin iron-containing crystals of such size, amount, composition, and magnetic properties to impart a coercive force of at least 200 oersteds to the material, and wherein the RF magnetic field has a frequency not in excess of about 10 kilohertz.

A method for reducing the mass of a tumor comprising localized magnetically-coupled, RF-induced hyperthermia mediated by a material which is non-toxic to animal tissue and which has incorporated therewithin magnetic iron-containing crystals of such size, composition, concentration, and magnetic properties to impart a coercive force of at least 200 oersteds to said material, and wherein the frequency of said RF magnetic field will not exceed about 10 kilohertz, allowing essentially only magnetic hysteresis heating to occur.
