Small Mammals + Tumors

  • Cytology is the microscopic examination of cell samples. These samples may sometimes be collected from the surface of the lesion under investigation, but more often, the sample is obtained by use of a special needle.

  • Ferrets can suffer from tumors in any part of their body, ranging from benign cancers of the skin to aggressive malignant tumors of internal organs. A large number of ferrets are affected by tumors of the lymphoid system. This handout will discuss lymphomas and lymphosacromas.

  • There are four major hormonal diseases in ferrets. Two of these diseases are covered in separate handouts, namely abnormally high levels of estrogen associated with persistent estrus in female ferrets (see Ferrets – Reproductive diseases), and abnormally high levels of insulin associated with the pancreatic tumor called insulinoma (see Ferrets – Tumors).

  • Ferrets can suffer from tumors in any part of their body, ranging from benign cancers of the skin to aggressive malignant tumors of internal organs. A large number of ferrets are affected by tumors of the lymphoid system and the pancreas.

  • Mast cell tumors are the most common skin tumor found in ferrets. They can also be found internally on the spleen. They arise from a cell type called a mast cell. In dogs and less so in cats, these tumors can vary from benign to highly malignant.

  • An insulinoma is a tumor that involves the beta cells of the pancreas. Beta cells are the cells that produce the hormone insulin. Insulinomas are surprisingly common in ferrets.

  • Common conditions of pet rabbits include snuffles, internal and external parasites, overgrown incisors, uterine problems (infections or cancer), and sore hocks.

  • Common conditions of pet rodents include respiratory diseases, anorexia and lethargy, overgrown teeth, and tumors.
