The vet sent the mass that was taken out for a biopsy and the oncologist is the one who couldn't tell which kind it was, but did say it was one of the two.

The reason he said for multiple surgeries is based on his opinion is that the tumor is really slow, not growing very fast and has low metastasizing chances, under 5 percent. He also said we could amputate if we like the next time the tumor appears, but his recommendation is multiple removals as long as the tumor stays manageable to give her the most time with 4 legs, but he is giving us the choice. Cost is not factored because the vet is a family member who is doing this for free. He did mention that it is highly likely it will come back, but there is a slim chance it might not reappear. He said we could do radiation, but he said for a dog for 10 years older we could do it, but there is a large cost of 5-10k possibly since we would have to go to ucdavis to probably to do it, so a better solution would be amputation. He said after amputation there would be no need for any other treatment.

He said amputation would remove the cancer and that is really the only thing that can help. He also said the 2 years is just the average, but many factors could play a part in the average which might not even relate to my dog. He said just to basically see what happens since who knows what could happen after the amputation when done. I think he recommends the multiple removals, since there is only a slim chance of metastasizing, she's in no pain right now, and based on her age 10-11 since she was a rescue, that she could possibly have other issues or cancers pop up after the amputation at anytime, which might put her through the pain of amputation for no reason.
