Transmissible cancers—cancers which can spread between individuals by the transfer of living cancer cells—are believed to arise extremely rarely in nature. One of the few known transmissible cancers causes facial tumours in Tasmanian devils, and is threatening this species with extinction. Today, scientists report the discovery of a second transmissible cancer in Tasmanian devils. The discovery, published in the journal Proceedings of the National Academy of Science, calls into question our current understanding of the processes that drive cancers to become transmissible.
