I quickly looked through my files on animal diseases - these files are small as the topic is of very limited interest - and did not find anything on cancer in wild chimps. I do have parts of articles on atherosclerosis in wild elephants (and primates - it seems baboons are the best studied primate in this regard), pneumonia in bighorn mountain sheep, tuberculosis in wild deer in India, viral and bacterial diseases in marine mammals [I believe cancer is found in marine mammals but did not photocopy that section of the subject reference. If my memory is correct, the reference I have parts of, had some unpleasant photos of dolphins with large tumors and cancers.] Also: encephalitis in multiple animal species, conjunctivitis in birds, etc. If one is willing to spend some time in a good research library, I suspect you might find published evidence of cancer in at least some wild animals. Until the references are cited, those in denial may prevail. Two good references here are: JOURNAL OF WILDLIFE DISEASES WILDLIFE DISEASE NEWSLETTER Those who deny that wild animals get sick, should spend some time reviewing back issues of the above in a good research library. It makes for interesting reading! Tom Billings
