Today, our Bear had a large mass removed from his back, and the vet says it is a probable fibrosarcoma. We won't know for certain until we get the path results back later this week, but I'm trying to be prepared for the worst. Has anyone else had experience with this? I have read a few messages on past FML's about it. What are treatments in ferrets? Our vet is talking about chemotherapy and radiation, and may refer us to Colorado State, but I'm afraid this will be very, very expensive. What have others done? We're so demoralized by this. It came out of the blue! :(:( -Tasha [Posted in FML issue 3010]
