Exponential growth is the unique characteristic of life. Destruction of a cancer colony by x-ray therapy follows unique exponential form. The primary target of x-rays (ionizing electromagnetic radiation) must be that reaction which is responsible for exponential growth. Because exponential growth is inherited this chemical reaction must be the creation of life, of cancer and this target. 434 MHz Ultra High Frequency non-ionizing radiation increases the x-ray kill per unit dose whilst enhancing its exponential character. Both must target the same chemical system of glutathione because in cyclic conversions of reduced oxidized reduced forms, energy is produced exponentially. This cycle has been named Re. The additional energy for this cyclic reaction Re is supplied by the anaerobic glycolysis of one molecule ofd-glucose converting to two molecules ofl-lactic acid.
