I hope it'll be alright, I guess an abscess would be better than a tumor, but I really believe I would have noticed it before now if it had been growing at the rate cancers usually do. I just worry, because he's over two years, and any he has still trouble with that antibiotics resistant myco anyway (which also has come back a bit already, I just haven't brought him in yet again for the rattling, because it's still fairly quiet, and it's not like I can bring him in for daily injections all the time, if there even was still an antibiotic that worked). I just hope this thing doesn't expand so that his breathing or swallowing is impaired before something can be done, and that the emergency vet is experienced with this type of thing in rats (it's always something of a roulette with the emegency hour vets in their practice, though one of the regular doctors is the one my local rat club recommended, but obviously I can't wait until Monday).
