  • Patent number: 5658234
    Abstract: This invention relates generally to a method for treating a tumor comprising the steps of selecting a target substance which has at least one component with an atomic or molecular resonance frequency or frequencies different from the atomic, molecular or cellular resonant frequencies of normal cells, locating or depositing the target substance within the tumor, and irradiating the target substance with electromagnetic wave energy at a frequency or frequencies corresponding to the atomic or molecular resonance of the component such that the component absorbs energy from the electromagnetic wave, resulting in the release of heat sufficient to destroy, terminate or slow the growth of the tumor without adversely affecting the viability of normal cells.
