Dear X - Most general practitioners will refer a thoracic case due to the intricacies of anesthesia and the requirement for assisted ventilation. When you open the thorax, the lungs collapse, and a machine or a good tech needs to "breathe" for the animal. There is a trick to closing the thorax as well, to make sure that the lungs stay inflated, and post-operative follow-up is important to ensure that all stray air is removed from the chest, so that the lungs do not collapse as well. We haven't even mentioned the small size of the ferret thorax and difficulty working in there. It can be done, but usually only at a specialty surgical clinic or veterinary school. However, if it is a tumor, the chance of recurrence is good due to the difficulty in complete excision. You would have to think long and hard in pursuing this option in any 8- year-old.
