Tasmanian devil facial tumour disease (DFTD) is a transmissible cancer that has devastated wild devil populations by over 80% since its discovery in 1996 — the hub's DFTD page likely addresses: welfare impacts of tumour growth (feeding impairment, starvation, secondary infections), the ethics of captive insurance populations (confinement stress vs extinction prevention), and the welfare implications of vaccine and immunotherapy research — DFTD is one of only three known transmissible cancers in nature, making it both a conservation emergency and a scientific curiosity — its inclusion in the hub bridges wildlife disease ecology and animal welfare ethics
