Computer model predicts who needs lung cancer screening

A machine learning model developed by researchers can predict lung cancer risk with an 83.9% sensitivity, identifying those who need screening for the disease. The model uses just three predictors: age, smoking duration, and pack-years of smoking, making it a simplified approach to determine high-risk populations.
