Don't get too worried. Call the vet, see if he had noted it on the chart. If not, a little trip to the vet wouldn't hurt.

There are so many types of lumps. Shiloh's last lump was hard, solid, immovable and on her leg. All the things her vet did not like. She had it removed and it was not cancer. Killian has had quite a few lumps removed, all benign. At the moment Killian has one over his hip. We are watching it. (He can't undergo surgery even if it is something ). So hang in there and don't worry. The vet can tell you if he feels it should be removed or just watched. Good luck and keep us posted.
