The efficacy of means exploited currently for cancer prevention and treatment appeared to be very low. New insights into the origin of the disease are sorely needed. The present article synthesizes the results from integrative reconsideration of actual data on cancer from the viewpoint of recent developments in pathology, epidemiology, immunology, genetics, and evolution. In contrast to the 80 years old hypothesis of somatic mutative origin of carcinogenesis, the revealed set of evidence showed the origin of cancerous clones is based on inherent constitutional incongruence between the regulators of cell physiology and their targets realized in inherent immunity of cancerous cells to normal regulation of cell replication and tissue growth. The incongruence arises out of both genome mutations which led to interethnic differences in the regulator-receptor structures and intercourse between ethnoses, the regulator-receptor evolution of which has been processed to deal with different ecologic conditions. The current pandemic spread of cancer is brought about growing expansion of interethnic xenogamy favored by growing industrialization, urbanization, globalization, and migration. The proposed hypothesis of genome intrusion in the origin of cancer induces new research ideas and proposals for cancer prevention and therapy.
