It sounds as if your vet is concerned that your dog has a malignant tumor, most likely squamous cell carcinoma. If there is suspicion about the malignancy of a tumor the best course of action is to have it removed. I can understand your concerns about Dahlia undergoing surgery but it would be safer and easier to remove it now, while it is smaller, then it would be if it was left to continue to grow.

I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
