In a recent study published in the International Journal of Cancer, researchers at the Mayo Clinic, Rochester, USA, examined the association between drinking alcohol and kidney cancer risk.
In the study, a total of 652 patients with kidney cancer and 1,366 control patients were examined by the researchers. The researchers found that risk of developing kidney cancer was 48% lower for the patients who consume alcohol compared to the patients who don’t. The risk was lowest in men who drank up to two alcoholic beverages a day, and one to one and a half drinks for women; additional drinks were found to not be beneficial.
The researchers suggest that genetic variations of alcohol dehydrogenase, a protein that helps break-down alcohol, are associated with the risk of developing kidney cancer in people who drink alcohol.
