Expert Opinion: Prostate Cancer Screening: Do Benefits Outweight Risks?
Screening for prostate cancer could reduce deaths from the disease by about one-fifth, according to long-term results of a European study involving over 162,000 men. Despite this new evidence for the efficacy of prostate-specific antigen (PSA) testing, the authors question whether the benefits of screening outweigh the harms, and recommend against routine PSA screening programs.
