My vet said she didn't see anything she thought indicated cancer, but I also would hope they're wrong about IBD. That's also what got me is that I'm not seeing any of the "indicative" neurological signs like regurgitating, weight loss, or any twisting/stargazing, but that could also be because she's in early stages of the disease?
I'll be sure to check out more diagnostic options, I saw University of Florida also does testing specifically for IBD so maybe my vet can send samples there too.
