Lymphoma
What is it?
Lymphoma is the most common cancer in ferrets, affecting the lymph nodes, spleen, liver, bone marrow, and other organs. It can strike ferrets of any age.
What signs should I watch for?
Signs to watch for include enlarged lymph nodes, weight loss and poor appetite, lethargy, labored breathing, and diarrhea.
How is it diagnosed and treated?
Blood work, imaging, and a biopsy of an affected lymph node or mass confirm the diagnosis. Treatment may involve chemotherapy, surgery for an isolated mass or enlarged spleen, and supportive care.
Can it be prevented, and what's the outlook?
- Outlook varies with the form and the ferret's age.
- Ferrets usually tolerate chemotherapy well.
- Yearly exams help catch problems early.
