found a lump on my cat, vet said it didnt look bad but she aspirated it, came back as mast cell. she sounded completely negative, like there was no chance, but from what i've read online they dont know whether its bad or spread until they remove it and test it, its 1 bump, i'm pretty sure i caught it early, how serious are these things? btw he's going to get it removed tomorrow
thanks
