The nurse is conducting a community health fair. Which screening test is most appropriate to offer for colorectal cancer to average-risk adults aged 50+?

COLORECTAL CANCER SCREENING GUIDELINES: ACS recommends beginning at age 45 for average risk (lowered from 50 in 2018). OPTIONS range from non-invasive to invasive: STOOL TESTS: Annual FIT (fecal immunochemical test) — most practical for community screening; FOBT (guaiac-based) — less specific; FIT-DNA (Cologuard) — every 1-3 years; VISUAL EXAMS: Flexible sigmoidoscopy every 5 years; CT colonography (virtual colonoscopy) every 5 years; COLONOSCOPY: Gold standard; every 10 years for average risk; allows biopsy and polyp removal during the procedure; COMMUNITY HEALTH FAIR CONTEXT: FIT testing is ideal — it's inexpensive, no preparation required, can be completed at home, and results are highly actionable (positive → refer for colonoscopy). PSA is prostate cancer screening for men; chest X-ray screens for lung cancer (but low-dose CT is preferred); upper endoscopy screens for upper GI, not colorectal.
