Simple nudges boost colon cancer screening rates
NCT ID NCT06710509
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether personalized reminders (like texts or emails) could encourage more people to return their at-home stool test kits for colon cancer screening. Over 2,100 adults aged 45 to 75 who had not yet returned their kit took part. The goal was to see if these gentle nudges could improve screening rates and catch cancer earlier.
