Some people are more likely to develop bladder cancer than others. You may be more likely to develop bladder cancer if you have the following risk factors:
- Smoking: Smoking is the most significant risk factor for bladder cancer and smokers are three to four times more likely than nonsmokers to develop bladder cancer.
- Older age: Bladder cancer is rarely found in those under 40.
- Exposure to chemicals: Coal soot, arsenic in water, or chemicals used to make rubber, certain dyes or textiles increase risk. In the United States, safety measures limit arsenic level in public drinking water.
- Previous cancer: A previous bladder cancer or previous cancer treatment, which involved certain drugs such as cyclophosphamide or radiation therapy to the abdomen or pelvis.
- Family history
- Hereditary conditions: Conditions such as hereditary nonpolyposis colon cancer (HNPCC or Lynch syndrome) increase the risk for developing bladder cancer.
