i got home from the vet today... it seems koko has an oral mass on the left side of her jaw. they took xrays and fortunately it has not penetrated the bone but shes not looking good. the mass rapidly developed (over a few days) and she now has a huge mass on the lip and inside of her mouth and what seems to be another growing opposite it on the top jaw. for now she is breathing and eating ok, but has stopped running on her wheel and taking pleasure in her normal activities. it doesn't seem painful but she is obviously distressed by it since she keeps licking it and "playing" with it. they will be calling me on tuesday to let me know what the oral surgery team has to say and get the test results back. our vet said that at best its benign and can be cut out using laser surgery but at worst its a squamous cell carcinoma and they may have to remove half her jaw. shes about 1 year old and it kills me to have to put her through something like that. im not sure what her quality of life will be post surgery. has anyone gone through this and have some input for us? would you put her through a jaw removal surgery? let it be and just try to make her as happy as possible or put her down (obviously as last resort)? im freaking out thinking about it.
