I have had a small bump on my right testicle for as long as I can remember (at least 8th grade, I'm 25 now). It is only on the right testicle and feels similar to when you run your finger over a zit on your forehead. I've recently become reobsessed with what it is since the only information I can find for a bump on the testicle itself is cancer, but I feel like it would have grown or manifested itself more by now. Any thoughts on what else it could be?
