Today, Jewel had bloodwork done, and it was awesome. She had a dental, and was spayed, and had two small tumors removed. Her vet said not to waste my money on the lab, unless I wanted to employ an oncologist for her. They are not lipomas, or cysts, but he got them all, as far as anybody can tell. He says it's fairly likely that she'll start to get more. She was intact for far too long, and she's an IG.
So, the current plan is to feed her lots of good food, lots of good supplements, and give her lots of love. If anything else comes up, we'll deal with it.
