Bladder cancer occurs when abnormal cells multiply without control in the bladder. Most bladder cancers are transitional cell carcinomas (cancer that begins in cells that normally make up the inner lining of the bladder).

Other types include squamous cell carcinoma (cancer that begins in thin, flat cells) and adenocarcinoma (cancer that begins in cells that make and release mucus and other fluids).The cells that form squamous cell carcinoma and adenocarcinoma develop in the inner lining of the bladder as a result of chronic irritation and inflammation.

Signs and Symptoms of Bladder Cancer

What causes bladder cancer?
The incidence of bladder cancer is associated with a number of factors, both genetic and environmental. Smoking is associated with an increase in the risk of developing bladder cancer due to damage to the lining of the bladder. Similarly, exposure to chemicals, and exposure to chemotherapy may increase the risk of developing bladder cancer. Chronic bladder inflammation may also be a contributing factor.  A personal or family history of cancer will increase the probability of developing this disease.
