Key points
- To lower the risk of bladder cancer, don’t smoke and be especially careful around certain kinds of chemicals.
- Blood in the urine is the most common symptom.

Overview
Cancer is a disease in which cells in the body grow out of control. When cancer starts in the bladder, it is called bladder cancer.
The bladder (sometimes called the urinary bladder) is a balloon-shaped organ in your lower abdomen, near the pelvis. It stores urine from the kidneys until it is passed out of the body.
