شاب عمره ٢٢ سنة تعلّم الفحص الذاتي للخصيتين. أي ملاحظة يجب أن يبلّغ عنها الطبيب؟

A 22-year-old man has learned testicular self-examination. Which finding should he report to his provider?

1. A soft cord-like structure at the back of the testicle
2. One testicle is slightly larger than the other
3. The left testicle hangs slightly lower than the right
4. A firm, painless lump on the front of one testicle

Answer: D) A firm, painless lump on the front of one testicle. A firm, painless lump is the commonest sign of testicular cancer, which peaks between 15 and 35 years. A slightly lower left testicle and a small size difference are normal, and the soft structure at the back is the epididymis.
