Although I recognize Sukie's knowledge and experience in this area, I think this statement could be misleading. While almost all mast cell tumors are benign, but not every growth that looks like a mast cell tumor actually is. Just last week, I had a ferret growth biopsied despite having every reason to believe it was a mast cell tumor, and learned it was a hemangiosarcoma. Kara & 19 ferkids [Posted in FML issue 3967]
