The risk of developing prostate cancer could be reduced by taking a common painkiller.
According to research published in the journal Cancer Epidemiology, Biomarkers and Prevention, taking the drug acetaminophen over a long period of time can lower the risk of developing the disease.
Led by Dr Eric Jacobs, the team used data for 78,485 men and estimated a 38 per cent reduced risk of developing prostate cancer among the men who had taken 30 or more of the tablets a month for five years of more.
They also discovered that the risks of developing an aggressive form of the cancer were reduced.
Dr Jacobs commented: "While the results of this observational study suggest that long-term regular acetaminophen use may be associated with lower prostate cancer risk, our findings require replication by other studies, and do not justify use of acetaminophen to prevent prostate cancer.
"Acetaminophen is considered relatively safe when used at recommended doses but unintentional acetaminophen overdose is an important cause of acute liver failure."
He added that the results could lead to further studies, which may provide further insights.
