Devil Facial Tumour Disease (DFTD) is extremely unusual as it is only one of three recorded cancers that can spread like a contagious disease. The cancer is passed from devil to devil through biting. The live tumour cells aren't rejected by the animal's immune system because of a lack of genetic diversity among Tasmanian devils.
