I thought about this study a bit more and finally realized that the study had been published early online back in January when I had first written about it . Upon looking back, I'm glad to say that I'm at least consistent. Whether that's good or bad is open to debate. Sure REDEEM was a randomized controlled trial good for demonstrating cause & effect. However, in this situation, reality isn't so much black & white as it is various shades of gray. It turns out that dutasteride, just like finasteride, can decrease the incidence of prostate cancer but only while increasing the risk of high grade cancer . You'll need to decide for yourself whether less hair loss or improvement in prostate symptoms is worth the potential risk/side effect.
