When it comes to preventing cancer, you've probably heard a lot of conflicting advice. (And may I just say, that it's a bummer that the only study linking chocolate to cancer prevention is funded by Mars.) As a former smoker, I can tell you I'm very interested in what my chances of getting the dread disease are, and how I can lower my risk factors. Whether you've been healthy all your life, or you're like me, a former sunworshipper or smoker, it's time to truth-squad this stuff. We're devoting a segment entirely to cancer prevention; so if you've got questions (what the heck is an antioxidant?), go ahead and post them here.
