Bladder Cancer Risk Factors: Infections
Being infected with certain parasites increases the risk of
bladder cancer. These parasites are common in tropical areas but not in the United States.
Bladder Cancer Risk Factors: Treatment With Cyclophosphamide or Arsenic
Cyclophosphamide and arsenic drugs that are used to treat cancer and other conditions raise the risk of bladder cancer.
Bladder Cancer Risk Factors: Race
Caucasians develop bladder cancer twice as often as African Americans and Hispanics and the lowest rates of bladder cancer are among Asians.
Bladder Cancer Risk Factors: Gender
Men are 2 to 3 times more likely than women to get bladder cancer.
Bladder Cancer Risk Factors: Family History
People with family members who have bladder cancer are more likely to develop the disease and researchers are studying changes in certain genes that may increase the risk of bladder cancer.
Bladder Cancer Risk Factors: Personal History of Bladder Cancer
People who have had bladder cancer have an increased chance of getting the disease again.
Other Bladder Cancer Risk Factor Considerations
Other bladder cancer risk factor considerations include chlorine and saccharin. Chlorine is added to water to make it safe to drink by killing deadly bacteria. However, chlorine by-products can form in chlorinated water. Researchers have been studying chlorine by-products for more than 25 years and although there is no proof that chlorinated water causes bladder cancer, researchers are continuing to study chlorine by-products. Some studies have found that saccharin, an artificial sweetener, causes bladder cancer in animals. However, research does not show that saccharin causes cancer in people.
