DFTD is a naturally occurring infectious cancer first observed on the east coast of Tasmania in 1996. This cancer is rapidly spreading across the island, the devil’s only native habitat. DFTD is predicted to spread throughout Tasmania within 5 years. Because the disease has a 100% mortality rate, preservationists are concerned that the devil may face imminent extinction.
