Well, she could just leave it alone if it's causing her no pain. I can't see that her allergy to drugs would have much to do with having the cyst removed though. I'm sure her PHysician knows of her allergies and a person can't be allergic to ALL drugs. If the Dr. has recommended removal of the cyst I would certainly follow thru with that. I'm sure it wouldn't have been recommended if the Dr. didn't think it was important.
Dear junenine, A cyst is a fluid filled structure and if it is not causing her any problem could be just left alone without any operation. If a procedure is necessary to treat the cyst, decisions regarding medications needed as anesthetic would take into account her allergies by the surgeon doing the procedure.
