What is Bladder Cancer?

Bladder cancer is cancer of the sac that collects and holds urine until it exits your body. It's the fourth most frequently diagnosed cancer in men and the 10th most frequently diagnosed cancer in women. Most people who develop the disease are older adults — less than 1 percent of cases occur in people younger than 40.

Smoking is the greatest single risk factor for bladder cancer. Exposure to certain toxic chemicals and drugs also makes it more likely you'll develop the disease. Although some of these risk factors can be controlled, the incidence of bladder cancer hasn't decreased significantly in recent years. Even so, increased understanding of the disease means the outlook for people with this type of cancer is brighter now than in the past.

If the cancer is detected early — before it has moved beyond the lining of your bladder — you have a better chance of a successful treatment with minimal side effects. Treating bladder cancer that has spread is more difficult and involves more extensive procedures. But several new approaches can offer a better quality of life. In addition, researchers are studying ways to help prevent the disease in the first place.
