Do i have epididymis?

  i am 13 and i recently got my yearly physical. A few weeks ago i detected a really small size lump on my right teste. It was smaller than a pee (about 1/4 the size). When i went to my physican yesterday, He did not detect anything. But I am still worried this is something bad. Is it? Please help

Dear John,
Monthly self examination of the testicles is recommended.  If you detect a "lump"  it may or may not be cancer, but follow up with a physician is recommended.  If suspicion warrants, a testicular ultrasound study and blood tests for testicular tumor markers can be performed.  These are not necessary if your physician is confident that the lump you felt is a normal anatomic structure.
