According to a population-based study of Swedish men, blood PSA level at age 60 can differentiate men who benefit from prostate cancer screening and those who don’t. Dr. Catalona said, “In my opinion, it is a large leap of faith to recommend stopping PSA testing at age 60 based on the meager available data, especially since prostate cancer is a major cause of suffering and death, disproportionately higher in older men, and a PSA blood test is such a simple thing to do.”
