一位 50 歲女性詢問護理師有關乳房攝影篩檢的頻率。根據標準健康促進指南，下列哪項回答最合適？
A 50-year-old female client asks the nurse about the frequency of mammograms for breast cancer screening. According to standard health promotion guidelines, which response is most appropriate?
- AMammograms are only necessary if you find a lump during self-examination.只有在自我檢查發現腫塊時才需要進行乳房攝影檢查
- BYou should have a mammogram every 2 years.您應該每兩年接受一次乳房攝影檢查
- CYou should have a mammogram every year.✓ 正解您應該每年接受一次乳房攝影檢查
- DYou only need a mammogram once every 5 years after age 50.50 歲之後只需每五年接受一次乳房攝影檢查
乳房攝影篩檢的核心概念在於早期發現無症狀的微小腫瘤。根據美國癌症協會 (ACS) 指引，45-54 歲女性應每年接受篩檢，55 歲以上可改為每兩年一次或自由選擇每年一次。早期診斷能顯著提高五年存活率並增加保留乳房的手術機會。選項 B 的每兩年一次通常適用於較高齡（55+）或特定國家政策；選項 A 錯誤，因為等到摸到腫塊通常已非早期；選項 D 的 5 年間隔遠低於臨床標準，無法有效發揮篩檢作用。護理師應強調定期篩檢而非僅依賴自我檢查。
Standard guidelines, such as those from the American Cancer Society, recommend annual mammograms for women aged 45 to 54 to ensure early detection of malignancies. Waiting for palpable lumps or extending intervals to five years delays diagnosis and reduces survival rates. Biennial screening is typically recommended for women aged 55 and older.
美國 ACS 建議 45 歲開始每年篩檢，而台灣國民健康署則提供 45-69 歲（以及 40-44 歲有家族史）女性每兩年一次免費乳房摄影。美國護理師更強調個別風險評估與保險涵蓋範圍，台灣則多配合政府兩年一篩的政策。
