At this time, there is no certain way to prevent bladder cancer. The best way to lower your risk is not to smoke. And a recent study found that drinking plenty of fluids could lower the risk of bladder cancer. In the study, people who drank at least eleven cups of fluid a day were half as likely to get bladder cancer as those who drank fewer than six cups a day.

It's also important to follow good work safety practices if you work with certain chemicals called aromatic amines, and benzidine and its derivatives, combustion gases and soot from coal, possibly chlorinated aliphatic hydrocarbons, chlorination by-products in heated water, and certain aldehydes (e.g., acrolein used in chemical dyes and in the rubber and textile industries). Those are the chemicals most likely encountered in the industries listed above under Risks of Bladder Cancer. Fortunately, most of these chemicals are no longer in general use.
