    "body_text": "Researchers followed 492,812 adults after a negative fecal immunochemical test across four health systems. Fifty-four percent repeated screening in more than three quarters of eligible years, 30 percent returned at least once, and 16 percent never retested. Advanced cancer accounted for 19 percent of diagnoses among never-retesters versus 12 percent in the other groups. Outreach practices differed sharply between systems, but this observational analysis cannot assign every outcome to reminder design alone.",
