Bladder Cancer 

Bladder cancer forms in the tissues of the bladder, a hollow organ that stores urine. The wall of the bladder is comprised of several layers of tissue. Bladder cancer usually begins in cells in the lining of the bladder and it becomes more difficult to treat as it advances through each layer of the bladder.

Nearly 90 percent of people diagnosed with bladder cancer are over the age of 55, and men are nearly three times more likely to get bladder cancer during their lifetime than women. Bladder cancer is the fourth most common cancer diagnosed in men.
