Oregon Health & Science University (OHSU) Scientists Tout New Prostate Cancer Test
PORTLAND, Ore. (AP) -- Oregon scientists say a simple test can identify men at high risk of life-threatening prostate cancer even after a biopsy finds no signs of it. The key, researchers say, is "PSA density," which compares the size of a man's prostate with his levels of a cancer-related protein called prostate-specific antigen.
