This book is a collection of most of the studies of the biological applications of laser energy, with particular emphasis on the author's work with malignant tumors.

After reviewing the important events in cancer research during the previous 25 years, the author describes the theory of laser energy and the mechanism of its production. Various types of lasers are shown in excellent photographs.

The parameters and experimental results of laser in the most common tumor-test system, that of Syrian hamster cheek pouches, are reviewed next. Convincing photographs and photomicrographs support the theorem that laser energy does have a lethal effect on cancers growing in the cheek pouches. All of the tumor systems which the author tested are carefully reported.

The use of laser energy in human cancer treatment is still strictly a research tool. The author reviews several hypotheses explaining the varying effects from laser energy in human tumors, and
