Mammogram timing diverges as experts push toward personalized screening
Guidelines on when to start and how often to screen with mammograms clash among major groups, reflecting imperfect risk prediction. ACP recommends average-risk women 50–74 get mammograms every two years, with 40–49 discussing pros/cons; USPSTF starts at 40 every two years; ACS favors yearly screening for 45–54 (start at 40 optional) and allows switching after 55. Dense breasts and emerging tools like 3D mammography, broader genetic risk tests, and AI risk models may tailor later practice, but experts say regular screening remains most beneficial when a shared plan is followed with a clinician.
