What is Bladder Cancer?
- Bladder cancer begins when cells in the urinary bladder start to grow uncontrollably. As more cancer cells develop, they can form a tumor and spread to other areas of the body.
- The bladder is a hollow organ in the pelvis with flexible, muscular walls. Its main function is to store urine before it leaves the body. Urine is made by the kidneys and is then carried to the bladder through tubes called ureters.
- When you urinate, the muscles in the bladder contract, and urine is forced out of the bladder through a tube called the urethra.
