The bladder is a hollow organ in your lower abdomen that stores urine. Bladder cancer occurs in the lining of the bladder. It is the sixth most common type of cancer in the United States.

Kidney Cancer

You have two kidneys. They are fist-sized organs on either side of your backbone above your waist. The tubes inside filter and clean your blood, taking out waste products and making urine. Kidney cancer forms in the lining of tiny tubes inside your kidneys.
