Cancer is common in rabbits and
several different types may be seen
Common types of neoplasia
reported to occur in rabbits include :
- Interstitial cell tumour of the testes
- Lymphosarcoma (juvenile and young) - may be a genetically transmitted
autosomal recessive disease. Can develop in any tissue, but most
often involves the lymph nodes, skin, kidneys, liver and spleen.
- Mammary tumours - spontaneous, mainly carcinomas.
- Myxoma virus infection - results in skin tumours (fibromas)
- Nephroma (juvenile) develops in the embryo
- Papilloma - caused by papilloma viruses, and often involves the skin (Shope
papilloma) or mouth. In the skin they can be persistent, become malignant
and undergo metastasis. In the oral cavity the warts are small and grey-white
nodules and often form under the tongue as well as on the gums.
- Squamous cell carcinoma
- Uterine adenocarcinoma :
- It is most often seen in Dutch, Havana, French Silver and Tan
rabbits. It is reported to be rare in Belgian and Rex rabbits.
- It most often occurs in rabbits over 3 years. Over 50% of rabbits
may be affected in predisposed breeds.
- It may be hormone dose-dependent (oestrogen)
- Signs of reproductive failure may be noticed in the early stages -
abortion, failure to conceive, resorption, stillbirths, small litter
size, retained fetuses.
- There may be a direct link between uterine hyperplasia, or pregnancy
toxaemia and the later development of cancer
- Metastatic spread - (local or haematological) is common after the
disease has been present for over 9 months
Many forms of cancer in rabbits lend themselves to surgery if they are
recognised early enough, and hysterectomy can prevent the development of
uterine adenocarcinoma. Chemotherapy and radiation are reported to have been
used successfully in rabbits as well as amputation for localised bone cancer
in a limb.
