Bladder cancer happens when cells in your bladder grow abnormally and out of control. The cancer cells can spread to other parts of your body. The bladder is the part of your urinary tract that stores your urine until you are ready to let it out.
The cause of bladder cancer isn't known. It can often be treated successfully if it is found early.
