What Is Bladder Cancer?

Cancer is the growth of abnormal cells in the body. Bladder cancer typically begins in the inner lining of the bladder, the organ that stores urine after it passes from the kidneys. Most bladder cancers are caught early, when treatments are highly successful and the disease has not spread beyond the bladder. But bladder cancer tends to come back, so regular check-ups are important.
