    Dr. Michael Roizen answered:
    In many ways, oxidation is a good, naturally occurring thing that happens in your body. Your body needs oxidation for your immune system to work, for your body to protect itself. It helps kill off old cells to make room for new ones. So it's not a bad thing, but it has the potential for being bad. When oxidation turns bad is when there's too much (your body's version of rusting), so that its products (free radicals) damage the DNA to cause malignant cells or inhibit the mechanism that can clear cancer cells from your body.
