 Through this program, the investigators will test a systematic colon cancer screening outreach strategy for increasing screening completion among uninsured patients, not up-to-date with screening. The intervention will consist of mailed screening invitations, with processes such as phone reminders to promote screening and evidence based follow up. All patients will be randomly assigned to receive mailed invitations to complete a home fecal immunochemical test FIT. Some patients will be randomly assigned to receive a small financial incentive on completion of FIT testing.
