U.S. Cancer Screening Trial Shows No Early Mortality Benefit from Annual Prostate Cancer Screening

Six annual screenings for prostate cancer led to more diagnoses of the disease, but no fewer prostate cancer deaths, according to a major new report from the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial, a 17-year project of the National Cancer Institute (NCI), part of the National Institutes of Health. The PLCO was designed to provide answers about the effectiveness of prostate cancer screening.
