How often is gFOBT performed for routine screening?

• A. Semi-annually
• B. Biennially
• C. Every 5 years
• D. Annually

Answer: (D)

gFOBT detects hidden blood in the stool, which can appear intermittently with developing polyps or cancers. Doing the test every year increases the chance of catching a bleed within a reasonable time frame and allows timely follow-up with colonoscopy if the result is positive. Testing less often could miss intermittent bleeding and delay diagnosis, while more frequent testing doesn’t provide additional meaningful benefit for routine screening.
