I'm 24. A little less than 2 years ago (like 19 months ago) I felt a painless pea shaped "thing" on the backside of my left testicle. I have no idea if it was always there and I just now felt it for the first time, or if it was new. It doesn't hurt when I touch it.
To locate it, I kind of have to put my finger at the bottom of the testicle on the front side, and then sort of scoop under and go up very slightly. That's where it seems to be located... behind the testicle near the bottom.
It's hard for me to remember, but it is possible that around that time I did experience some groin pain (pretty much only if I bent over to touch my toes). However, I do a lot of weight training, so I figured that was the cause, which it certainly might have been. The pain went away completely within a week or two. Again, this was almost 2 years ago.
My first question is, based on this description, what could it be?
My second question is, does the fact that it has been there and remained (as far as I can tell) exactly the same for almost 2 years make it any less likely that it's something serious, such as cancer?
I know an examination by a doctor is the only way to know for sure, but I'd still love to hear some opinions anyway. Thanks in advance for any help.
