Michelle, if the vet is thinking more along oral SCC, Metacam and ab's are a better treatment than steroids, especially with him being FIV (steroids aren't recommended due to the already suppressed immune system). Someone on CC was trying a new treatment, and it has been working wonders so far, can't find the name though - apparently COX inhibitors (which Metacam is) supposedly have a tumour growth retardation effect)
