Body fat
causes cancer according to a scary report from
the American Institute for Cancer Research and the
World Cancer Research Fund that reviewed 7000 studies. Obesity creates "a low-grade chronic inflammatory state" that promotes cancer. This report seems more foreboding than others of its ilk, e.g.: "Even small amounts of excess body fat, especially if carried at the waist, increase risk." Drinking is also carcinogenic: better limit yourself to 2 drinks a day if you're male and 1 if you're female. (Of course,
breathing is also bad, and so is
sunlight. ) Conclusion: you can live a really long time if you don't like to eat or drink, though you want to avoid taking this to
extremes.

Devil facial tumor disease has ravaged the population of Tasmanian Devils in the last decade. DFTD is a
transmissible cancer, i.e. the tumor cells themselves (which differ genetically from their host animal) are the agent responsible. The disease is spread by biting and other contact, and the resulting grotesque tumors interfere with feeding and lead to starvation.
Poor immune response may be partially responsible. This is actually not the only such disease: canine transmissible venereal tumor is an
analogue that has been known to be contagious since the 19th century. (CTVT, however, gets a proper immune response.)
