As far as I know, and I've had ferrets treated for lymphoma as well
as adrenal disease, melatonin implants are used for supressing the
symptoms of Adrenal Disease. The only "cure" for AD is surgery to
remove the adrenal.

Melatonin implants are used as a first line treatment for AD. Better
is Lupron injections or depots, but more expensive. The best thing of
all is surgery (if your ferret is a good surgical candidate).

Do you ferrets or one of them have lymphoma? If your vet said that
melatonin can help with it he's mistaken. It has nothing to do with it.
Lymphoma can be treated well with Tuft's protocol. I have a copy of it
here and also the contact info for vets if you need. It is chemo, but
it is the best option and with a good vet can be affordable if you have
the extra money to spend. Over almost six months, I totaled around $300
to do this for a fuzzie rescue. She went into remission but sadly died
of an unrelated tumor of the vena cava.

There are other things for lymphoma but I am not up on them. But as far
as I know, melatonin is not going to do anything at all for the ferret.
Prednisone also does not (it is only given if you are not going to
treat the disease, to relieve swelling and pain, and to reduce the
size of the tumors) but it does nothing overall to stop the lymphoma.
