The lesions she had were cancerous mass cell tumors. Mast cell tumors are very common in ferrets and are almost always a benign mass in this species. In other species, especially dogs, they are very aggressive, nasty tumors, and your vet may be thinking of their behavior in dogs rather than in ferrets. I would think twice, then think again, before even considering chemotherapy of any kind for mast cell tumors in ferrets. Usually removal is completely curative, and I have known many ferrets whose owners opted to not have them removed who did fine with the exception of a scabbed and sometimes itchy mass. Dr. Ruth ***************************************** Save lives - spay or neuter your pet. [Sukie note: This is a source of confusion on and off for vets who aren't used to ferrets. Ferrets have been put on inappropriate meds and sometimes destroyed by well meaning vets who just did not know better.] [Posted in FML issue 3944]
