Hello. I noticed a new bump on my right testicle. I do a self-check every couple of months or so, and the last time I did one it definitely was not there. The lump (or bump) is very very tiny, and feels pretty firm. It's really very small - smaller than even a BB, about the size of a pin point. It's very near the epididymis (spelling), but it's not quite on it - but that's the area that it's by though. It is definitely on the testicle, and not free-floating. There definitely does seem to be a tiny bit of space between the epididymis and the bump, so I'm fairly certain that it's on the testicle and not on the epididymis. It's not ultra sensitive, but if I try to press on it firmly to tell how hard it is, I can feel a slight pain in my lower abdomen that just hangs around for a few seconds. The best way I can describe it is that it reminds me of a small zit that's ready to pop in terms of size and how hard it feels. I realize that there's no way to be certain without going to a doc, but I'm going to give it a few days and see if there are any changes before I make an appointment. I posted here with the hopes that someone might be able to give me a clue as to what it might be before I make that appointment, just to put my mind at ease for the time being (or to inform me that I should go to the doctor right away if this sounds for certain like cancer). Also, I'm a 27 year old white male. Thank you for your time.
