Investigations on rats with an implanted tumour-carcinosarcoma of Walker (26 animals), cancer of the mammary glands, RMK-1 (75 animals) and in mice with spontaneous cancer of the mammary gland (188 animals)-have shown that the application of a low-level diode laser beam (890 nm) can effect the growth of the experimental tumour. Minimal doses produce a tumouro-static effect, while other doses produce different effects. Low level laser irradiation promotes dystrophic and necrotic changes in tumoural nodes.
