Have Cat Questions? Ask a Cat Vet Online.
It should have been removed at the teeth cleaning like you asked.
Now you need to schedule another appt. if this vet doesn't want it removed, maybe you should seek a second opinion. If it has grown over 2 yrs...it needs to come of and tested to see if it is cancerous.
If it is fluid filled, it may be just a cyst, meaning it is not a cancer type growth...but cysts need be surgically removed if they are getting too large and/or bothering the animal. A growth around the eye can be irritating to the animal.
Anesthesia always carrys a certain risk. If your cat did okay with the dental...he should be okay for this as well. Since it is on his eye margins, the surgery itself is not a life threatening type surgery...usually these removals are very quick.
The best thing to do is ask your vet if he/she is comfortable doing the procedure.
Even benign growths can cause problems if left long term...but if the cat is bothered by it now, have it removed before it gets larger.
