The bladder is a hollow organ at the base of the pelvis that collects urine from the kidneys prior to passing it from the body. Nearly all invasive bladder cancers begin in the lining of the bladder and then spread into the bladder wall. These are called transitional cell cancers (or urothelial cancers).
Less common invasive bladder cancers include squamous cell carcinomas and adenocarcinomas that are also likely to spread into the bladder wall.
Nationwide there were 2446 new cases of invasive bladder cancer in 2012.
Bladder cancer is much more common in men.
