一位 40 歲病人詢問為何平均風險者每十年進行一次大腸鏡檢查。護理師的最佳回答為何？
A 40-year-old client asks why a colonoscopy is suggested every 10 years for average-risk individuals. What is the nurse's best response?
- AIt is primarily used for identifying hemorrhoids主要用於識別痔瘡
- BIt is the only way to diagnose colon cancer是診斷大腸癌的唯一方法
- CIt allows for the detection and removal of precancerous polyps✓ 正解允許檢測並移除癌前息肉
- DIt stimulates the growth of healthy colon tissue刺激健康大腸組織的生長
大腸鏡檢查是預防大腸癌的黃金標準，核心價值在於「早期發現、早期處理」。大腸癌多數由腺瘤型息肉（Adenomatous polyps）演變而來，此過程通常需數年時間。透過大腸鏡，醫師可以直接切除這些癌前病變，從根本上中斷癌症發展的病理路徑，達到一級與二級預防的目的。護理師在衛教時，應強調檢查的預防性意義，而非僅將其視為診斷工具。
Colonoscopy is the gold standard for colorectal cancer prevention because it allows for the direct visualization and removal of adenomatous polyps, which are precancerous lesions that typically develop over several years. By excising these polyps, the procedure interrupts the pathological progression to cancer, achieving both primary and secondary prevention goals.
在美國，根據美國癌症協會（ACS）指引，大腸癌篩檢年齡已下修至 45 歲。台灣健保提供 50-74 歲每兩年一次糞便潛血檢查，若異常再安排大腸鏡，而美國臨床對於大腸鏡的普及率與篩檢起始年齡更為積極。
