U.S. task force: End routine prostate cancer screening

NEW YORK (Reuters) -

A task force advising the U.S. government on Monday recommended against routine use of the prostate-cancer screening test called PSA, or prostate specific antigen, for lack of a discernible health benefit.

Like a draft proposal last October, the U.S. Preventive Services Task Force gave PSA screening a D, for "don't recommend" in healthy men.

PSA, a blood test, is a poor screening tool because PSA levels can rise for reasons unrelated to cancer, including age and prostate enlargement. Yet an elevated PSA level can trigger a biopsy to check for cancer.
Most biopsies show no cancer, which means the PSA was a false positive.

Against the tiny benefit of PSA testing, the task force weighed its harms. At least 15 percent of PSA tests will trigger a biopsy, after which up to one-third of men experience pain, fever, bleeding, infection, difficulty urinating, or other problems requiring medical attention, studies show.

"When you stack up those harms, the tiny or zero benefits do not outweigh the risk," said task force co-chair Dr. Michael LeFevre of the University of Missouri Medical School. Because PSA tests cannot distinguish between aggressive and indolent cancer, said ACS's Brawley, "men are rendered impotent and put in diapers, and for what?" he asked. "They never really had cancer in the first place."
