What is bladder cancer (urothelial cancer)?

In bladder cancer (urothelial cancer), cells grow abnormally in the urinary bladder to form a tumor. Most bladder cancers start in the inner lining of the bladder, which is called the urothelium. If the tumor spreads outside the bladder, it’s considered advanced bladder cancer.
