Bladder cancer and alcoholic beverage consumption

A population-based case-control study of bladder cancer was conducted in 10 geographic areas in the United States. Risk of bladder cancer was not related to overall alcohol intake, nor to amounts of wine, beer, or spirits consumed. Alcohol also did not interact with known or suspected bladder carcinogens to increase risk, and no evidence was found that indirect mechanisms associated with alcohol ingestion the risk of bladder cancer.
