Summary

This study tested whether offering a simple blood test instead of a colonoscopy or stool test would encourage more people to get screened for colorectal cancer. Researchers enrolled 297 adults aged 45-75 who had previously skipped or refused traditional screening. The goal was to see if a blood-based test is more acceptable and improves screening rates, especially in underserved communities.
