I am sorry that it was cancer afterall. Blue has two places on his neck right now and the vet suspects skin cancer...but I am not ready to get them removed because Blue has gone through so much with hyperthyroid, diarrhea, and weight loss. I just think he would struggle to recover and could die as a result of having them removed. I agree with you...if it comes back, I would likely not subject her to it all over again (depending on her age at the time and the location of it on her body). That is the sucky thing about cancer...whether in an animal or a human...once you have it, it is likely to come back somewhere else at some point.
Have I mentioned lately that I HATE CANCER? It has taken too many people and animals that I love!
