Which interval is used for colon cancer screening with FIT kit in average-risk individuals?

• A. Every 1 year
• B. Every 2 years
• C. Every 3 years
• D. Every 5 years

Answer: (B)

Stool-based screening tests like the FIT look for hidden blood in the stool, which can signal colorectal cancer. A single negative result doesn’t guarantee there isn’t cancer because bleeding can be intermittent and the test only captures one point in time. Repeating the test at regular intervals increases the chance of detecting cancer that might bleed only on certain days.

In this context, the interval is set at every two years to balance the test’s ability to catch cancer with practical considerations like patient adherence and resource use. If a FIT result is positive, the next step is diagnostic colonoscopy to confirm and locate the cancer or a treatable lesion.

So, screening every two years with a FIT kit is the recommended pattern for average-risk individuals in this scenario.
