''Once you tell people there's a cure for something, the more likely they are to pressure doctors to prescribe it.'' -Robert Ehrlich, drug advertising executive.
"Opinions are like sphincters, everyone has one." - Chris Rangel
This offers support for the idea that the disease apparently began with a single sick devil, probably in the mid-1990s, that directly spread the cancer cells by biting other animals. The authors propose that cancer cells are dislodged from one animal and essentially transplanted to another as a result of bites inflicted around the mouth.
"Devils jaw wrestle and bite each other a lot, usually in the face and around the mouth, and bits of tumor break off one devil and stick in the wounds of another," said Ms Pearse.
