Boston AI startup forecasts breast cancer risk from mammograms before tumors form

Boston-based Clairity, led by radiologist Dr. Connie Lehman, has FDA authorization to use an AI system that analyzes mammograms to predict a woman's risk of developing breast cancer, enabling preventive actions and tailored screening. Trained on over 400,000 mammograms with five-year follow-ups and tested on 77,000 images, the deep neural network outperformed traditional risk calculators and could expand to younger ages and more diverse populations, though the model remains a 'black box' in parts; investors include ACE Global Equity and Santé Ventures as Boston's health-tech scene grows.
