Devil facial tumour disease (DFTD) is an aggressive non-viral clonally transmissible cancer which affects Tasmanian devils, a marsupial native to Australia.[1][2] DFTD was first described in 1996.[2] In the subsequent decade the disease ravaged Tasmania's wild devils. Affected high-density populations had up to 100% mortality in 12–18 months.[3] Between 1996 and 2015, DFTD wiped out 95% of affected populations.[4]
