Transmissible cancers are passed between individuals by the transfer of living cancer cells. These diseases are rare in nature. Among mammals, only three transmissible cancers are known, affecting dogs and Tasmanian devils. Several transmissible cancers have also been identified in marine bivalve molluscs, including various species of clams, cockles and mussels. https://www.tcg.vet.cam.ac.uk/about
