AI Model Accurately Predicts Breast Cancer Risk Across Diverse Groups

June 6, 2025

An AI model accurately predicted breast cancer risk in a racially and ethnically diverse screening population using mammogram data.

Key Details

  • Study included 206,929 women (average age 56.1) from a province-wide screening program starting at age 40.
  • AI model used both current and up to four years of prior mammograms for risk scoring.
  • Model achieved AUROC of 0.78 overall, 0.77 in East Asian, 0.77 in Indigenous, and 0.75 in South Asian women.
  • 4,168 breast cancer cases confirmed over an average 5.3-year follow-up.
  • Model showed consistent performance across age groups and ethnicities.

Why It Matters

Demonstrating robust, consistent AI performance across diverse populations supports its broader clinical adoption. Such risk models may enable more personalized and equitable breast cancer screening and resource allocation.
