Telephone 843-838-3602 Received Accepted Published Cancer is a significant medical and societal problem. This reality arises from the fact that an exponential and an unrestricted cellular growth destabilizes human body as a system. From this perspective cancer is a manifestation of a system-in-failing. A model of normal and abnormal cell cycle oscillations has been developed incorporating systems science complexity and chaos theories. Using this model cancer expresses a failing subsystem and is characterized by a positive exponential growth taking place in the outer edge of chaos. The overall survival of human body as a system is model suggests however that cancer s exponential cellular growth and disorganized complexity could be controlled through the process of induction of differentiation of cancer stem cells into cells of low and basic functionality. This concept would imply reorientation of current treatment principles from cellular killing cyto-toxic therapies to cellular retraining cyto-education . Key words systems complexity chaos cancer melatonin physical activity 1. Introduction Motto The more we study the major problems of our time the more we come to realize that they cannot be understood in isolation. They are systemic problems which means that they are interconnected and interdependent. Fritjof Capra 1 . Cancer is a significant biologic and social problem. Effective cancer control should be reflected in a progressive reduction
