[Effects of cascatol and sodium selenite on the onset and development of breast tumors induced in rats by N-methyl-N-nitrosourea].

Experimental evidence is presented on effects of the vitamin complex cascatol containing vitamins E, C, beta-carotin and sodium selenite on the onset and development of breast tumors induced in rats by N-methyl-N-nitrosourea. Cascatol used in combination with sodium selenite significantly reduced the incidence of tumors from 95.5% in the control group to 50% in the test group, prolonged a latent period of tumor development and inhibited growth of breast tumor.
