Let's start with this observation: Among underserved patients whose colorectal screening was not up to date, mailed outreach invitations resulted in markedly higher CRC screening compared with usual care. Outreach was more effective with FIT than with colonoscopy invitation. So I love that FIT simply gets more folks screened (at a cheaper cost).

A very reasonble screeninng test for those at average risk:
