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.
