What is Bladder Cancer?

Bladder cancer refers to any of several types of malignant growths of the urinary bladder. It is a disease in which abnormal cells multiply without control in the bladder.

The bladder is a hollow, muscular organ that stores urine; it is located in the pelvis. The most common type of bladder cancer begins in cells lining the inside of the bladder and is called transitional cell carcinoma (sometimes urothelial cell carcinoma).

In the United States, bladder cancer is the fourth most common type of cancer in men and the ninth most common cancer in women.

More than 50,000 men and 16,000 women are diagnosed with bladder cancer each year.

One reason for its higher incidence in men is that the androgen receptor, which is much more active in men than in women, plays a major part in the development of the cancer.
