German biochemist Dr Otto Warburg earned double doctorates in chemistry and medicine and won the Nobel prize in 1931 for his discovery of the nature and mode of action of the respiratory enzyme, showing that cancerous cells can live and develop, even in the absence of oxygen.
"All normal cells have an absolute requirement for oxygen, but cancer cells can live without oxygen - a rule without exception. "Deprive a cell 35% of its oxygen for 48 hours and it may become cancerous." Dr. Warburg has made it clear that the root cause of cancer is oxygen deficiency, which creates an acidic state in the human body. Dr Warburg also discovered that cancer cells are anaerobic (do not breathe oxygen) and cannot survive in the presence of high levels of oxygen, as found in an alkaline state.
