Mammography AI Flags Cancer Risk Up to 10 Years Before Diagnosis

Three commercial mammography AI algorithms produced elevated cancer scores as far as 10 years before clinical diagnosis in a Swedish study (Radiology), with signal strength increasing closer to diagnosis — suggesting AI may detect long-horizon mammographic risk. Exact AUC/sensit…

• Retrospective Swedish cohort study; three commercially available mammography AI tools evaluated — specific sample size not reported in source.
• Cancer risk scores rose progressively over the decade preceding diagnosis, implying a detectable mammographic phenotype years before conventional detection; no head-to-head accuracy numbers provided in the available excerpt.
• Key limitation: retrospective design with cases drawn from a single country's screening program limits generalizability; real-world lead-time benefit and over-diagnosis implications remain unquantified.
