This document discusses how cancer cells adapt their energy production pathways to survive stressful conditions. Malignant or benign status depends on energy proportions, which impacts mutation rates and later prognosis. Cancer cells repress their main energy production pathways, so anaerobic glycolysis becomes the dominant energy generation style. This produces high amounts of lactic acid waste. Cells that generate energy powerfully and use it suitably can resist carcinogens, mutagens, and carcinogenesis.
