Cancer Center Brings Clinical Trials to Eugene (Business‪)‬

Byline: Tim Christie The Register-Guard CORRECTION (ran Jan. 6, 2009) Business: An article in Sunday Business about cancer research in Eugene incorrectly described what is measured by a PSA test. The test measures the amount of prostate-specific antigen, a protein produced by the cells of the prostate gland, in the blood. The results of a PSA test alone do not provide enough information to distinguish between benign and cancerous prostate conditions, according to the National Cancer Institute. A higher-than-normal PSA number can indicate the presence of cancer, but it also can indicate the presence of a benign, or noncancerous, prostate condition.
