Ive done a lot of research so far and everyones comments have helped a lot so thank you! :)
She is a really nice mare but from what everyone has said and the research I've done its basically a 50/50 chance at it getting worse or not growing back....The lady said the the vet removed one on a horse in the same spot and things are looking good for that horse but it will cost 1000$ to have done....And from what you guys have said it sounds like having the surgrey done could also "anger" the sarcoid causing it to grow back even worse. And with it on the eyelid I don't know if that's something Id want to mess with if theres a chance it could come back worse....
Cherie you said since its a dormant to leave it alone incase of waking the sarcoid up, do you think sarcoid-ex would help with it with out waking it up?
Also why and how do they speard to other places on the body when it starts in one spot like the face?
