http://www.smartgroups.com/message/readmessage.cfm?gid=1423922&messageid=568 It is hard to guess how long a ferret with lymphosarcoma will live. It depends on where the cancer cells spread to and what organs are damaged, etc. I do agree with Dr Williams, and I also start most of these cases on hi dose pred therapy.
