一位 40 歲男性詢問護理師睪丸癌的徵兆。關於自我檢查，哪項教學資訊是正確的？
A 40-year-old male asks the nurse about signs of testicular cancer. Which information is accurate for teaching self-examination?
- AReport any firm, painless lump on the testicle immediately✓ 正解立即回報睪丸上任何堅硬且無痛的腫塊
- BExpect the testicles to be completely smooth without any ridges預期睪丸表面完全光滑且無任何突起
- CConduct the examination once every year每年進行一次檢查
- DPerform the exam only if urinary symptoms occur僅在有泌尿系統症狀時才進行檢查
睪丸癌好發於 15-35 歲男性，雖題目為 40 歲，但衛教原則相同。自我檢查（TSE）的核心在於早期發現異常。正常的睪丸摸起來應平滑且有彈性，附睪（Epididymis）位於睪丸後方，觸感較軟且細長，不應被誤認為腫塊。任何無痛性硬塊（Firm, painless lump）都是重要的警訊，必須儘速就醫。每月定期檢查有助於建立對自身器官狀態的認知，以便及時發現變化。
Testicular cancer most commonly occurs in men aged 15 to 35; although this question concerns a 40-year-old, the teaching principles are the same. The core of testicular self-examination (TSE) is early detection of abnormalities. A normal testis should feel smooth and elastic, and the epididymis, located behind the testis with a softer and more elongated texture, should not be mistaken for a mass. Any firm, painless lump is an important warning sign and warrants prompt medical evaluation. Performing the examination regularly each month helps establish familiarity with one's own anatomy so that changes can be detected in a timely manner.
