Thermomagnetic surgery for cancer.

Thermomagnetic Surgery is a unique technique that takes advantage of the phenomenon of hysteresis heating of a ferromagnetic material to produce intense but controlled temperatures within solid organs or tumors to cause coagulation necrosis. By controlling the power of the electromagnetic coil system, the degree of heating of the tumor can be controlled through temperature monitoring that allows limitation of the area of destruction to the disease process and avoids damage to surrounding structures. If the ferromagnetic material is delivered by the arterial route to the tumor or organ, there is an additional beneficial effect of ischemic necrosis of the tissue and in time more concentration of the ferromagnetic particles. This new technique is applicable to selected cases of human cancer because no ill effect has been shown to exposure of the electromagnetic field or the ferromagnetic material in experimental animals.
