一位 45 歲無大腸癌家族史的客戶諮詢大腸鏡檢查頻率，護理師應提供何種建議？

根據美國癌症協會（ACS）最新指引，平均風險族群建議從 45 歲開始進行大腸癌篩檢。若選擇大腸鏡作為篩檢工具，且結果正常，建議每 10 年進行一次追蹤。此建議旨在早期發現癌前病變，顯著降低大腸癌發生率與死亡率。
According to the most recent American Cancer Society (ACS) guidelines, average-risk individuals should begin colorectal cancer screening at age 45. If colonoscopy is chosen as the screening method and the result is normal, follow-up colonoscopy is recommended every 10 years. This recommendation aims to detect precancerous lesions early and significantly reduce both the incidence and mortality of colorectal cancer.
美國建議 45 歲開始篩檢；台灣國健署建議 50-74 歲每 2 年進行一次糞便潛血檢查，若異常再安排大腸鏡。
