Clonally transmissible cancer
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.
Transmissible cancers are rare in humans.A malignant fibrous histiocytoma was contracted from a patient by a surgeon when he injured his hand during an operation.
所以?我以為新聞討論的癌症範圍僅限人體。不知道到底是誰在幫誰戴帽子...
