Generally, we treat lymphoma only after it has been diagnosed. If the FNA
shows nothing, then a biopsy of one of these large lumps should be the
next step, rather than treatment of a diseases whose presence has not
been established.

Hyperthyroidism has yet to be documented in ferrets - cat and human
replies to this method notwithstanding. And, if we did see it in ferrets,
there is no guarantee that the clinical signs would be the same as in the
dog or cat. If you look up hyperadrenocorticism or insulinoma in your
Merck manual - you will read description of diseases which bear no
resemblance to what we see in the ferret.
>Would a hyperthyroid ferret have enlarged lymph nodes and spleen?
While you can pursue this by running a standard t3/t4 panel, I think that
for close to the same price you may be able to get that lump excised and
analyzed to see what it is, and this would be a much more cost-effective
way to go.
