 A new DFTD tumor-type cancer was recently uncovered on 5 Tasmanian devils (DFT2), histologically different from DFT1, leading researchers to believe that the Tasmanian devil "is particularly prone to the emergence of transmissible cancers".Soft-shell clams, "Mya arenaria", have been found to be vulnerable to a transmissible neoplasm of the hemolymphatic system — effectively, leukemia.The cells have infected clam beds hundreds of miles from each other, making this clonally transmissible cancer the only one that does not require contact for transmission.
