The bladder is a hollow, muscular walled structure that is a storage vessel for waste produced by the urinary system. Bladder cancer occurs when abnormal cells develop in the bladder and grow out of control.
Risk factors for bladder cancers include age, use of tobacco, occupation, infections, medications for other cancers, race, being male, family history and personal history.
The most common symptom of bladder cancer is blood in the urine. Blood may occur intermittently, or each time you urinate. Other symptoms include painful and frequent urination, or a feeling of needing to urinate without being able to do so.
