Cancer treatment by intracellular hyperthermia

A process for the treatment of cancer cells in living tissue of a patient comprising the following steps:

• introducing into the living tissue of the patient minute particles of a size not greater than one micron and capable of being metabolized by the cancer cells and capable of an increased rate of metabolism or oxidation by the increased availability of oxygen,
• absorbing said minute particles intracellularly into the cancer cells, thereafter, increasing the oxygen level of the blood of the patient, and thereby increasing the rate of intracellular chemical reaction in the cancer cells due at least in part to the intracellular presence of said minute particles, and generating intracellular heat therein, and
• continuing said increasing the oxygen level step until the intracellular temperature has increased at least 8.0 degrees Centigrade but not more than 9.5 degrees Centigrade to selectively induce thermal death of the cancer cells.
