What is the recommended interval for iFOBT screening for those identified as average risk?

The recommended interval for immunochemical faecal occult blood testing (iFOBT) in individuals identified as average risk is every two years. This recommendation is grounded in the understanding that regular screening can effectively detect colorectal cancer at an early stage when it is most treatable.

Screening every two years strikes a balance between ensuring that potential colorectal issues are identified in a timely manner while minimizing the burden of unnecessary invasive procedures for individuals who may not require more frequent testing. Thorough studies have shown this interval to be both effective in maintaining sensitivity to identify cancers and polyps and practical for patient adherence.

Interval recommendations are based on evidence from clinical research and guidelines established by health authorities, which promote early detection to improve outcomes while considering the healthcare system's capacity and the patients’ quality of life.
