根據美國癌症協會與相關預防醫學指南，平均風險成年人進行糞便免疫化學檢測（FIT）的頻率為每年一次。若檢測結果為陽性，則需進一步安排大腸鏡檢查以確診。其他選項的頻率過長，無法達到有效的篩檢效益，會延誤早期病灶的發現時機。
According to the American Cancer Society and related preventive medicine guidelines, average-risk adults should undergo fecal immunochemical testing (FIT) once per year. If the result is positive, colonoscopy is required to confirm the diagnosis. The other options have intervals that are too long to achieve effective screening, delaying the detection of early lesions.
