Abstract
The role of frequency modulation in the Magic Light anti-cancer therapy was investigated both in theory and in clinical trials. The existence of at least four different optimal modulation frequencies is required for cancer treatment. This was disclosed and is explained by the presence of at least of four different kinds of cancer cells within the same cancer, whereby each cancer cell type has its own speed of proliferation. The application of several different frequencies for cancer treatment in turn, during each treatment session, thus allows the Magic Light therapy to cure any type of cancer faster and completely.
