Anything that increases your chances of getting a disease is called a risk factor. The main risk factors for bladder cancer include:

Smoking. Cigarette smokers are much more likely than other people to get bladder cancer.

Being older than 40, being male, or being white (Caucasian).

Being exposed to cancer-causing chemicals, such as those used in the wood, rubber, and textile industries.

What you eat. A diet high in fried meats and fats increases your risk for bladder cancer.

Parasites. There is a parasite that causes schistosomiasis, which can increase your risk. This condition is sometimes found in developing countries and rarely occurs in North America.
