Regular use, and especially long-time regular use, of aspirin may decrease the risk of prostate cancer (PCa) overall and advanced PCa, according to the findings of a meta-analysis published online ahead of print in International Urology and Nephrology.

Their meta-analysis of 24 epidemiologic studies found that regular aspirin use was associated with a 14% lower risk of PCa overall and a 17% lower risk of advanced PCa. Long-time regular use (4 years or more) was associated with an 18% lower risk of PCa overall and a 30% lower risk of advanced PCa.
