3-4 years ago, I noticed this small hard lump on my testicle. It wasn't exactly ON smack bang my testicle, it was sort of right at the top of my testicles, heading towards the penis. Anyway, I didn't think anything of it it and a year later or so it disappeared.
4 years on, it is not there now at all. I thought it may have been testicular cancer at the time but I didn't get any real symptoms for it at all. No swelling, no enlargement of the testicle or anything. I once recall have a small pain in my abdomen for a day or 2, but then it went away and has never returned.
However, years on I am concerned that it may still be testicular cancer.
How can a lump just go? What would it have been?
