There is no sure way to prevent bladder cancer. Some risk factors such as age, gender, race, and family history can’t be controlled. But there may be things you can do that could lower your risk.
Smoking is thought to cause about half of all bladder cancers. If you are thinking about quitting smoking and need help, call the American Cancer Society for information and support at 1-800-227-2345.
Limit exposure to certain chemicals in the workplace
Workers in industries that use certain organic chemicals may have a higher risk of bladder cancer. Workplaces where these chemicals are commonly used include the rubber, leather, printing materials, textiles, and paint industries. If you work in a place where you might be exposed to such chemicals, be sure to follow good work safety practices.
Some chemicals found in certain hair dyes might also increase risk, so it’s important for hairdressers and barbers who are exposed to these products regularly to use them safely. (Most studies have not found that personal use of hair dyes increases bladder cancer risk.) For more information, see Hair Dyes.
Some research has suggested that people exposed to diesel fumes in the workplace might also have a higher risk of bladder cancer (as well as some other cancers), so limiting this exposure might be helpful.
Drink plenty of liquids
There is some evidence that drinking a lot of fluids – mainly water – might lower a person’s risk of bladder cancer.
Eat lots of fruits and vegetables
Some studies have suggested that a diet high in fruits and vegetables might help protect against bladder cancer, but other studies have not found this. Still, eating a healthy diet has been shown to have many benefits, including lowering the risk of some other types of cancer.
