Don't smoke. That's one you've never heard before, right? It keeps popping up, but there's a reason: it's just horrible for you. Studies indicate that 12 percent of fatal colorectal cancers may be attributable to smoking.
Smoking increases your risk of developing colorectal cancer for two main reasons. First, inhaled or swallowed tobacco smoke transports carcinogens to the colon. Second, tobacco use appears to increase polyp size. In general, the bigger the polyp, the greater the chance it will become cancerous. (Check out the Polyp Size Gallery to see how big polyps are in real life.)
