Bladder Cancer Risk Factors
The cause of bladder cancer is not understood, but certain risk factors are known to increase an individual's risk of getting bladder cancer.
- Men are about three to four times more likely than women to develop bladder cancer, and older people are more likely to be affected. Up to 90% of those affected are over 55 years of age.
- Smokers are at an increased risk for development of bladder cancer.
- Exposure to certain chemicals used in manufacturing and industry (including paints and paint thinners, some hairdressing supplies, and certain dyes) are associated with a higher risk of bladder cancer, so people who work in certain occupations (workers in the rubber, chemical, and leather industries; hairdressers; machinists; metal workers; printers; painters; textile workers; and truck drivers) are at increased risk.
- Being infected with certain parasites that are common in tropical areas also increases the risk for bladder cancer.
