Has anyone here had success with treating their pet for cancer? Which vet? Did you go to A&M?

Horrible day. Wife took beloved Siamese to get his teeth cleaned today, and they found cancer throughout his jaw and sinus cavities. We are DEVASTATED. We have to wait for the biopsy to come back, but the vet said she is sure that, based on the abnormal cells in the sample, that it's some kind of bone cancer, advanced enough to cause him pain when he eats.

We are thinking my wife might come back to Houston or even take him to A&M if some kind of treatment might be successful for him. Sick at the thought of putting him down.
