The Bob Painter debates at the Radiation Research Society’s annual meeting “For” and “Against” stances in relation to the propositions that “Cancer is fundamentally a metabolic disease”. The "horse and the cart"
Unfortunately, due to the inefficiency of these oxidation reactions they generate small amounts of waste products. These are formed from one-electron reductions of O2 (electron leak) leading to the formation of reaction oxygen species (ROS; i.e., superoxide and hydrogen peroxide) that cause oxidative damage.
This inefficiency in metabolism slowly weakens the structure (genetic integrity) of the cart, negatively affecting intracellular communication as well all the processes necessary for the maintenance of normal cellular functions.

While ROS are required signaling molecules for living systems they also lead to the gradual accumulation of oxidative damage to the genome causing increased metabolic inefficiency as we age, accelerating the processes that lead to the onset of degenerative diseases associated with aging and cancer.
