The vet told me that they can't do any kind of surgery unless there is a biopsy done on the big tumor. Luckily, they still have the tumor that they removed a couple months ago, so they can do the biopsy on that one and I won't have to pay the lab fee. But the vet removed two tumors that day, and the replacement vet didn't know which was which, so he has to ask my vet when he gets back on Wednesday. He said that Icarus's tumor looks blue because it is probably very red, and red things look blue through skin, kind of like our veins. Icarus is now picking at the tumor on his belly..I'm not too sure what to do about that. So hopefully things will be worked out on Wednesday, and then he can have his surgery.
