- Parasitic cancer
A parasitic cancer or transmissible cancer is a cancer cell or cluster of cancer cells that can be transmitted from animal to animal. Cancer is not normally a contagious disease, but there are two known exceptions: one is in
dog s, and the other is in theTasmanian devil . These cancers have a relatively stable genome as they are transmitted. [ [http://www.retrovirology.com/content/3/S1/S92 Retrovirology | Full text | A sexually transmitted parasitic cancer ] ] Because of their transmission, it was initially thought that both diseases were caused by the transfer ofviruses , in the manner ofcervical cancer caused byHPV .*
Devil facial tumor disease (DFTD) is a transmissible parasitic cancer in theTasmanian devil . It was described in the scientific literature in 1995.
*Canine transmissible venereal tumor (CTVT) is sexually transmitted cancer between 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 malignantcell line in continuous propagation [cite journal |author=Murgia C, Pritchard JK, Kim SY, Fassati A, Weiss RA |title=Clonal origin and evolution of a transmissible cancer |journal=Cell |volume=126 |issue=3 |pages=477–87 |year=2006 |month=August |pmid=16901782 |doi=10.1016/j.cell.2006.05.051 |url=http://linkinghub.elsevier.com/retrieve/pii/S0092-8674(06)00912-3] .References
