Problems of Oncology, Antibiotics and Radiation Pathology at the III All-Union Congress of Pathologists

An introductory report on modern trends in oncology was made by IV Davydovsky (Moscow), who emphasized that tumors are a general biological process and, in principle, not a social disease, despite their great importance for humanity; in the external environment there is no specific non-competitive factor in the emergence of tumors, and the essence of tumors is in biological and histochemical transformations that change the course of morphogenetic processes. Of major importance in the pathogenesis of tumors are special products arising in the process of tissue life and representing specific metabolites. The problem of a cancer cell requires further in-depth cytological development.
