Bladder cancer

Abstract

Worldwide, approximately 330,000 new cases of bladder cancer (BC) are diagnosed each year and 130,000 people die annually of this disease. Median age at diagnosis is 70 years and men are at 3.8 times higher risk than women. In western countries, the lifetime risk of developing BC is 2.4 % and it is the fourth most common solid tumor in men. Exposures known to increase the risk of BC include tobacco smoke, occupational carcinogens, and schistosomiasis. Dietary factors that decrease BC risk include high water intake and cruciferous legume consumption.
