Pattern of Participation in Colorectal Cancer Screening from a Population-Based Screening Program in Iran.

Over four years of screening with FIT in Isfahan, 40% of the eligible population participated. Among those with positive FIT results, 20% underwent colonoscopy, and approximately 26% of these individuals were identified as having polyps or cancer. This study provides valuable insights into the uptake and outcomes of a population-based CRC screening program in Isfahan, Iran. The findings highlight the need for targeted interventions to increase participation rates and improve the detection of polyps and CRC cases.
