Background: Prostate cancer is one of the most common cancers among men, and it is unknown whether alcohol is associated with the development of prostate cancer.

Methods: The relationship between amount or type of alcohol and prostate cancer was studied in a pooled prospective setting conducted from 1976 to 1994 in Copenhagen, Denmark. The study population consisted of 12,989 subjects drawn from three different cohorts. During a mean follow-up of 12.3 yr, 233 subjects developed prostate cancer.

Results: None of the estimates for consumed amount of total alcohol diverged significantly from unity. Furthermore, drinkers of more than 13 beers, 13 glasses of wine, and 13 drinks of spirits had a risk of 1.03 (CI: 0.67, 1.60), 0.92 (CI: 0.42, 1.99), and 1.01 (CI: 0.52, 1.98), respectively, compared with abstainers of the given beverage of alcohol.

Conclusion: These results suggest that neither amount nor type of alcohol is associated with the risk of prostate cancer.
