New prostate cancer screening guidelines for men over 50

The American Cancer Society now recommends prostate-specific antigen blood tests every two years for men at average risk aged 50 to 69, reversing its previous guidance that patients decide with their doctors whether to screen. The society advises men at higher risk, including Black men and those with a family history, to begin annual testing at 45. The recommendations reflect stronger evidence about screening, which remains controversial because many tumors grow slowly.
