Abstract
Abstract A treatment of cancer by the application of external electromagnetic energy capable of the generation of heat in intracellular particles to induce selective thermal death of cancer cells in living tissue. This process allows for the selective treatment of cancer cells in living tissue without damaging the normal cells by the compartmentalized alteration of biophysical properties in the cancer cell.
