Abstract

In considering the therapy of cancer, the author has been interested in the internal dielectric heating property of microwaves and applied their capacity of rapid protein coagulation to medical treatment. With the purpose of utilizing this phenomenon for the resection of fragile parenchymatous organs, the experiment was conducted on rabbit livers, which were irradiated with microwaves for about 3 min. The effect of this phenomenon on cancer cells was also observed. Malignant tumors induced in rats were exposed to microwave radiation for 2 min.
