[Use of low-energy laser radiation in experimental and clinical oncology].

Experimental data concerning the action of low-energy (nondamaging) laser radiation on the malignant cells in vitro and on animal tumours are reviewed. It is shown that under certain conditions the helium-neon and helium-cadmium laser radiation inhibits the tumour cell growth. This inhibition may be mediated by the activation of the organism protection mechanisms. The encouraging results of the application of the low-energy laser radiation in the complex treatment of oncological patients are presented.
