Cutaneous mast cell tumor, basal cell tumor, squamous cell carcinoma and sebaceous epithelioma are the most commonly diagnosed skin cancers that occur in ferrets[1].

Common visceral tumors predominately include insulinoma and adrenocortical adenocarcinoma.

Types of neoplasia which have been recognized in ferrets are:

Type of neoplasia Location Metastatic index
Adenocarcinoma Visceral, mucosal Moderate
Adrenocortical adenocarcinoma Adrenal Moderate
Anal sac apocrine adenocarcinoma Anal gland Moderate
Basal cell tumor Skin Low
Chordoma Vertebral column Moderate
Fibroma Subcutaneous tissue Low
Fibrosarcoma Subcutaneous tissue Moderate
Hemangiosarcoma Skin Low, but locally aggressive
Histiocytoma Skin of face and limbs Low
Insulinoma Pancreas Moderate
Leiomyoma Uterus, ovary, esophagus Moderate
Lipoma Subcutaneous fat Low
Lymphoma Viscera High
Mast cell tumor Skin, viscera Moderate with visceral forms
Mesenchymoma Viscera High
Neuroblastoma Adrenal Low
Papilloma Skin Low, unless associated with SCCs
Plasma cell myeloma Blood, bone marrow High
Prostatomegaly Prostate Low
Piloleiomyoma Skin Moderate
