What is bladder cancer?

Bladder cancer occurs when abnormal cells within the bladder grow in an uncontrolled way.

The bladder is located in the lower abdomen. It is a hollow organ with a muscular wall that allows it to get bigger or smaller as needed. The bladder stores urine until it is released from the body through the urethra. Read More

If cancer cells do not spread beyond the lining of the bladder, this is called superficial bladder cancer.

Sometimes, cancer cells can spread into the muscle wall of the bladder or to other organs and lymph nodes. This is called invasive bladder cancer.Hide
