I remember reading a comment somewhere (HN? Slashdot?) years ago that talking about the mechanisms behind antioxidants. The gist was that antioxidants would help prevent cancer, up until the point where cancer manifests itself. After that, it would actually <i>help</i> cancer.<p>Note that the comment was speaking from a critical thinking perspective about the way cancer works and the way that the antioxidants work in the body (not from actual study results).<p>So this doesn&#x27;t seem so surprising to me.
