Got the result today, it turned out to be a tumour, one in each testicle, called a seminoma. They said it was most probably benign, were unable to say that it wasn’t malignant. Apparently most tumours of the testicles have high success rates of a cure if caught early enough, and removed, so I am really pleased he has a six monthly routine check, or I wouldn't have picked it up for ages.
Please everyone, CHECK THE BITS OF YOUR ENTIRE MALES REGUARLY!!!!!!! don't be shy 😉
Dylan is racing around like his usual self, so I shall just have to park it in the back of my mind, and reguarly check for lumps.
Feeling mostly relieved.

P.S. he's insured with the Kennel club, and there have been no quibbles, so that's good.
