Sorry to wait so long to update on Grizz. Well, after the biopsy results came back, the tumor is not malignant (though he said t is very likely she will eventually get a malignant tumor-with the fact that she already tends towards tumors). It is a mast cell skin tumor. I am so glad...but at the same time she still has a large skin tumor to deal with. My vet said he doesn't feel safe removing one so large from such a small animal (it's about the size of a silver dollar-about 1.5" in diameter) due to the risk of uncontrollable bleeding as well as closing up the resulting hole after removal. He said the university animal hospital in Auburn might be willing to do it...but the cost would be at least $500 0_o Apparently they require another biopsy and all that mess as well as other tests before even considering it (they could choose to not do it even after all that). He said at her age it may be better to try and manage it and keep it clean. That doesn't sound good to me :C I'm not sure how to feel or what to do at this point....
