Bladder cancer begins when in cells in the bladder grow out of control. The bladder is an organ that stores urine which is made in your kidneys and is transferred to your bladder by tubes called ureters. From your bladder, urine leaves your body through the urethra which is shorter in women and longer in men. Bladder cancers can affect not only your bladder but your ureters and urethra as well. There are different types of bladder cancers and they will have different treatment options.
