On a New Strategy of Preventive Oncology

The etiology of cancer is much wider than separately taken causal agent and rests against the most complicated interrelation and mutuality of many external and internal influences. Our researches with use of fluorescing antibodies to AFP, CEA and Ca-19-9 have shown that they are intensively besieged on a surface of cultivated malignant cells. It is the basic mechanism of tolerance and immunological escape, which is similar to pregnancy when «the maximal immunological most favored status” to developing fetus (semiallogenic transplant) is provided. The earliest revealing of first cancer cells, before steady community of cells and tumor angiogenesis were formed, has particular importance in the fight against cancer. The necessity of the specific completion of the weakened antineoplastic resistibility of people from high oncological risk groups is substantiated. The activity in this direction brought forth the design of embryonic anti-tumor modulator (EATM). EATM is composed of a wide pool of fetal proteins and proteoglycans isolated exceptionally from normal embryonic substances.
