Shrinkage of prostate led to overestimation of cancer risk in finasteride trial

Reanalysis of data from the first long-term randomized trial of a chemopreventive agent for prostate cancer shows that the excess prevalence of high-grade prostate cancer in the drug-treated group may be attributable to shrinkage of the prostate at the time of biopsy.
