Ars Technica reports that the American Cancer Society has reversed its 2010 guidance, now recommending routine PSA screening: men at average risk every two years from 50 to 69, and most high-risk men, including all Black men, yearly from age 45, with no screening advised at 75 and up. The society says new evidence since 2010 shows screening saves lives and that better case management curbs overdiagnosis and overtreatment of prostate cancer, which it estimates will kill over 36,320 US men in 2026.
