Does anyone have any experience with vaccine associated sarcoma? My poor little black kitty (Barney) apparently has this. I've done some searching on the web and am not feeling much better based on what I've found so far. Barney is scheduled for surgery on the 15th, but apparently these usually come back (is that right?) Unfortunately, he has a lump is the worst possible place (between his shoulder blades). I'm not sure how much I want to put him through (radiation, chemo, ??) if there's not much hope for a cure. Anyone have any hopeful stories they can share about this condition? I sure could use some hope right now.
