New Method Monitors Early Sign Of Oxidative Stress In Cancer

The growth of cancerous tumors is fueled, at least in part, by the buildup of free radicals---highly reactive oxygen-containing molecules. It stands to reason, then, that cancer should respond to treatment with antioxidants, which inhibit the rogue radicals, or with pro-oxidants, which go the opposite direction, increasing "oxidative stress" on cancer cells to the point of vanquishing them.
