About 8 weeks ago I was suffering with some small hard lumps on the head of my epididymis, the doctor said he couldn't feel them but looking online i think they may be spermatocele. I am 15 so i am in the testicular cancer range. Both my testicles feel normal, smoothe and firm but not hard. Could someone describe this heavy feeling to me because I can't understand it? Anyway these pain have come back but are weaker than the were before, could this be cancer? please reply
