ColonCancerCheck Mailed Invitations: An Evaluation

Summary

This study evaluates effectiveness of mailed invitations for colorectal cancer screening among screen-eligible Ontarians who are due for screening. The study will evaluate the effectiveness of mailed invitations in general (compared to no invitation) but will also determine if new invitation letters (2 letters for male, 1 letter for females) are more effective than current invitation letters used by the ColonCancerCheck program.
