How vitamin C weakens cancer cells ?

The mechanism that might explain the potential efficacy of vitamin C in treating lung and brain cancer relates to the cancer cells’ metabolism. As a consequence of the faulty metabolism that occurs inside the cancer cell’s mitochondria, these cells produce abnormally high levels of so-called redox active iron molecules. These molecules react with vitamin C and form hydrogen peroxide and hydrogen peroxide-derived free radicals. Scientists think that these free radicals drive cancer cell death by damaging the cell’s DNA. The free radicals are also thought to weaken the cancer cells and make them more vulnerable to radiation therapy and chemotherapy
