About bladder cancer
Bladder cancer is the sixth most common cancer in the United States, with more than 80,000 new cases diagnosed each year, according to the National Cancer Institute. Men are four times more likely to be diagnosed with bladder cancer from the disease than woman. Bladder cancer is the eighth most common cause of cancer death among men.
The bladder is a hollow organ that stores urine before it is discharged from the body. Urine travels to the bladder from the kidneys through tubes called ureters and from the bladder out of the body through the urethra. The lining of the bladder, call the urothelium, is made of cells called urothelial cells. Ninety percent of bladder cancers develop in urothelial cells, a type of bladder cancer called transitional cell carcinoma (TCC).
