@SimpleByte, the high aerobic glycolysis of cancer cells and the fact that cancer cells produce lactic acid in the presence of oxygen was first described by biochemist Otto Warburg. The phenomena has become known as the Warburg effect after him. Malignant tumor cells have much higher glycolytic rates than normal cells. This property has implications for cancer treatment since glycolytic inhibitors may affect tumor growth. In addition, aerobic glycolysis measurements can be taken of a tumor to see how the tumor is responding to treatment.
