Thanks DocJames for updating the article.  To the anonymous contributor, the article you reference states "Men taking finasteride may not have an increased risk of high-grade prostate cancer. Adjusting for the known effects that finasteride has on prostate cancer detection, investigators estimated that high-grade tumors (Gleason scores 7–10) were no more likely in the men taking finasteride than in the men taking placebo. However, because very few prostate cancers were detected at Gleason scores of 8 to 10, it is difficult to draw conclusions about this group."
From this text, I think it would be appropriate to say something like - In contrast to the FDA's stance, the National Cancer Institute believes that finasteride may increase the ability to detect cancer which accounts for the higher prevalance of high-grade cancer.  The article didn't specifically mention the NIH, but if you can cite it feel free to add it in the article and somebody will change it if they object.
