Closely connected to the physicochemical features of asbestos and its action on a cell is, obviously, its malignant effect. An enormous number of publications In the last two decades leaves no doubt of the fact that among those who were :ubjected to the action of asbestos dust, one can observe considerably higher Indices of mortality from the cancer of the lungs, mesothelioma of the pleura, or from cancer of other organs. The social signifi cance of this question for all industrially developed countries is borne out by the fact that the International Union Against Cancer (U.I.C.C.) created the Committee "Asbestos and Cancer." The problem is found among those which Interest the World Health Organization. In our work in conjunction with S. Yu. Troltskiy and M. R. Oulevskaya It was established that mortality from cancer of the lungs for 10 years among workers In asbestos-enriching factories was 3.6 times higher than among other populations (with standardization of sex and age). Among the patients with asbestosis, cancer of the lungs was the reason for death in 9%, and cancer other than that of the lungs in 31J of the cases. Even larger concern is caused by the reports from Canada (Cartier), ` USA "(Se 1 i coff' ist' ` aTi''1968 Coope^'ie jB) YuAR (Wagner, i960), Scotland (Maitr et alO , Finland (Kiviluoto. et al.), FRG (Bohlig), CSR (Navratil, 1968), etcl ^c`f -- " .ii-In recent years many investigators were able to obtain' ^-malignant growth --cancer, mesothelic;of-the pleurasand cancer^' * ' V ^asbestos and form of.the/latter Is shown (Smith et al, 1968)J. . and R.
