Nordström T, Clements M, Karlsson R, Adolfsson J, Grönberg H.
This study estimated the association between prescribed medications and the risk of either any prostate cancer or high-grade prostate cancer. The study included 185,667 men having a first recorded prostate specific antigen test and 18,574 men having a first prostate biopsy.
Regarding statins, the study found:
(a) Men using statins had a 16% increased risk of any prostate cancer compared to men not taking statins.
(b) Men using statins had a 25% increased risk of high-grade prostate cancer compared to men not taking statins.
Nordstrom concluded: "Use of any statins was associated with an elevated risk of being diagnosed with high-grade prostate cancer".
