After the US Prostate Cancer Prevention Trial found cancer in many men with low levels of prostate specific antigen (PSA), many debated which PSA level should lead to a biopsy recommendation. The US Preventive Screening Task Force (USPSTF) recently concluded, amid considerable controversy, that the evidence does not support recommending PSA screening for men under 75 years old at all, because the risks outweigh the benefits. Now, a study shows that physicians in a large Washington state health plan were being conservative in biopsy referral even before the USPSTF recommendation.
