A parasitic cancer or transmissible cancer is a cancer cell or cluster of cancer cells that can be transmitted from animal to animal.
Examples in animals
Cancer is not normally a contagious disease, but there are three known exceptions in dogs, Tasmanian devils and Syrian hamsters. These cancers have a relatively stable genome as they are transmitted.[1] Because of their transmission, it was initially thought that these diseases were caused by the transfer of oncoviruses, in the manner of cervical cancer caused by HPV.
- Devil facial tumour disease (DFTD) is a transmissible parasitic cancer in the Tasmanian devil.[2]
- Canine transmissible venereal tumor (CTVT) is sexually transmitted cancer in dogs. It was experimentally transplanted between dogs in 1876 by M. A. Novinsky (1841–1914). A single malignant clone of CTVT cells has colonized dogs worldwide, representing the oldest known malignant cell line in continuous propagation.[3]
- Contagious reticulum cell sarcoma of the Syrian hamster[4] can be transmitted from one Syrian hamster to another by means of the bite of the mosquito Aedes aegypti.[5]
It has been suggested that animals that have undergone population bottlenecks are at greater risks of contracting transmissible cancers.[6]
Instances of transmission of human cancer
Transmissible cancers are rare in humans.[7] A malignant fibrous histiocytoma was contracted from a patient by a surgeon when he injured his hand during an operation.[8]
