Hypothesis: Towards the origin of cancer epidemics and pathogenesis

BACKGROUND: The article presents the initial results of an attempt to reconsider current data about cancer epidemiology and pathogenesis from the viewpoint of recent all-pathological, immunological, genetic and evolutionary discoveries. METHODS: The investigation was based on a multidisciplinary approach to reassessment and reinterpretation of relevant current data about cancer epidemiology, clinical manifestations and course. RESULTS: In contrast to the current 50-year-old hypothesis of mutant maternal tumor and its subsequent metastasis, the revealed set of evidences allowed hypothesize that potentially cancerous cell clone spreads in human population and settles some persons‘ bodies during cross-fertilization of parents with genetically incongruent regulators of cell dividing and tissue growth. The clone is formed and distributed in the offspring‘s body before postnatal ontogenesis and for many decades exists in it like sleeping populations of smallest sizes. But at a relevant time of an individual‘s life (mainly after 40 years of age), according to a specific program of the clone ontogenesis, the populations come into sight as constitutionally immune against prevailing regulators of cell reproduction and begin to multiple uncontrollably thus initiating the cancerous growth. CONCLUSIONS: The new view of cancer origin and pandemic spread supplies a framework for understanding the genetic nature of cancer epidemics and its rising incidence in the current worldwide population. It also forces one to reconsider the perspective of future investigations and reassess both the means and methods for cancer prevention and healing..
