Bladder cancer epidemiology and demographics

Epidemiology
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 47,000 men and 16,000 women are diagnosed with bladder cancer each year. One reason for its higher incidence in men is that theandrogen receptor, which is much more active in men than in women, plays a major part in the development of the cancer.
