You know, you just beat me to it, really you did, I was sat here thinking the same, guys should also check themselves out thoroughly, and regularly, and be aware of any changes in themselves. My husband detected a testicular lump about two years ago now, so got it checked out, again thankfully, it was only a cyst and has since disappeared.
But you really can't be too careful about these things.
I personally felt like a bit of a fraud when I discovered it wasn't anything more than glandular tissue, and felt like I had wasted everyone's time
However, the staff in the Burney unit did everything in their power to assure me it certainly wasn't a waste of time, and I had absolutely done the right thing in getting checked out
Again the message being, it doesn't matter, if you feel or suspect there's something that's not quite right, get it checked! That's what the professionals are there for and they really do NOT mind.
Early detection is everything
