一位 50 歲女性詢問大腸鏡篩檢的頻率。對於無大腸癌家族史的個案,最合適的建議為何?

A 50-year-old female client is inquiring about the frequency of screening colonoscopy. What is the most appropriate guidance for a client with no family history of colorectal cancer?

  • APerform the test every 10 years✓ 正解
    每10年進行一次檢查
  • BPerform the test every 5 years
    每5年進行一次檢查
  • CPerform the test once a year
    每年進行一次檢查
  • DPerform the test only if blood is seen in stool
    僅在大便中看到血液時才進行檢查
Explanation · 中文詳解

根據美國癌症協會與相關指引,對於一般風險族群(無家族史),從 45-50 歲開始,大腸鏡檢查建議每 10 年執行一次,前提是前次檢查結果正常。若使用其他篩檢方式(如糞便潛血檢查),頻率則為一年一次。等待出現血便才檢查已錯過黃金預防期。

For average-risk adults starting at age 45 to 50, the American Cancer Society recommends colonoscopy every 10 years if previous results are normal. More frequent screening is reserved for high-risk individuals, while annual testing or waiting for symptoms like blood in the stool is inappropriate for preventive care.

✦ 台美臨床差異

台灣針對 50-74 歲民眾提供每兩年一次的免費免疫法糞便潛血檢查,陽性者才進一步安排大腸鏡,此為國家政策主流。
