My dog went in for her dental cleaning yesterday, and the veterinarian said they noticed something strange on her gum-line (inside, right canine area) and a small polyp on the bottom of her mouth (next to dental tool, touching dental tool in photo 1). 

They said the gum area around her canine on the right side looks like gingival hyperplasia (excessive gum growth), and advised that I keep an eye on it and bring her back in if it starts growing. At that point, they would perform a gingivectomy and have it biopsied. The vet said it “doesn’t look scary”, but nonetheless, I am scared. Especially with the second area of concern.

If relevant: My dog is 4.5 yrs old, mostly Malinois Pyrenees mix (plus a bunch of other breeds). She has never had any major health issues. Recently she has been dealing with relatively severe GI upset. She has had small/short bouts of diarrhea in the past, but it didn’t raise huge concern. This recent time we brought her into the vet and did a full blood panel and fecal. Everything looked normal, and her energy is fine, so we are thinking it may be IBS and are working with her vet on a diet plan. I assume they’d flag potential cancer related issues (like elevated white blood cell count) on her blood test, but I’m not sure what levels they’d be looking at since they were likely checking for parasite related issues. 

I plan to forward these photos to her regular (non dental) vet and ask for a second opinion, but also wanted to let Reddit chime in incase someone has seen something similar. 

Thank you! ♥️

Does this look like cancer?
