Is radiation or chemo indicated? From my huge data set of two cats they seem to tolerate chemo quite well; don't know much about radiation. I'll need to dig around for info on fibrosarcoma.
[ETA] I googled fibrosarcoma, and unfortunately it wasn't encouraging. This can be an aggressive cancer; the fact that it's on the leg might make it more manageable. You'll need to consult with your vet. Are you using a feline oncologist? They probably have more recent possible treatments than some of the dated stuff I found on a very quick search.
