The ePrognosis: Cancer Screening is a decision support app to help guide conversations with elderly patients of whether to start, stop, or continue breast cancer and/or colorectal cancer screening.

Based on risk calculators developed by expert health professionals at the University of California San Francisco and Harvard Medical School, the app assesses patient age, gender, BMI, symptoms, and functional impairment to calculate a mortality risk to help determine whether screening is more likely to help or harm a patient.
