Interested to see if reseach has been done on cancer rates in wild animals and what some of the causes might be. I'm not looking for zoo animals or domestic animals. Wild Animals should be the population for the study. Since only the strong mate in the wild, their genes are much strong then humans and can't help but put two and two together to think cancer is a result of bad decisions. I've heard that cancer in wild animals might be due to air and water polution. Just looking to see if there is any data on the issue.
Answer:
Yes, all animals including sharks get cancer. There is no immunity for any living cell . . all are susceptible to cancer whether it is human, pet, wild animal, or plant life. Cancer is an ancient disease that has been around since recorded time and beyond. There are fossilized remains of creatures that had cancer. It is not a new disease at all . . but there are more survivors so it makes it seem like it is new. Although there are carcinogens and things that place people at a higher risk for cancer . . there are absolutely no clear reasons why one person will get cancer and another will not. No one knows why a non-smoker will get lung cancer and no one can tell you why a heavy smoker does not always get cancer. As for wild animals getting cancer . . the majority of them die in the wild from their cancer. Some species can be brought to the brink of extinction from cancer.Tasmanian devil may become endangered species because of cancer
The population falls sharply as scientists search for a cure
http://www.iht.com/articles/2007/02/16/n...If you go to Entrez PubMed it contains articles for wild animals that have been found with various cancers and tumors, including many species of sharks and wild animals and birds from different continents."Cholangiocarcinoma with metastasis in a captive Adelie penguin (Pygoscelis adeliae).Renner MS, Zaias J, Bossart GD.
SeaWorld Cleveland, 1100 SeaWorld Drive, Aurora, Ohio 44202, USA.A captive male Adelie penguin (Pygoscelis adeliae), wild caught in 1976, died unexpectedly. Necropsy revealed cholangiocarcinoma with metastases to lung, pancreas, mesentery, and cloaca, the first known case of a penguin hepatic tumor.PMID: 12785690 [PubMed - indexed for MEDLINE]""Lymphosarcoma in a raccoon (Procyon lotor).Hamir AN, Hanlon CA, Rupprecht CE.
Department of Pathobiology, School of Veterinary Medicine, University of Pennsylvania, New Bolton Center, Kennett Square 19348, USA.A case of lymphosarcoma in a captive adult female raccoon (Procyon lotor) from northeastern Pennsylvania (USA) was observed in 1991. Prior to its death the raccoon had lost weight. At necropsy the carcass was in poor body condition and had pale mucous membranes. The thoracic and abdominal lymph nodes were enlarged, soft, and pale tan. Microscopically, there was effacement of normal lymph node architecture by sheets of mononuclear cells. These were well-differentiated small lymphocytes with distinct cell borders. Nuclei of these cells were darkly stained and mitotic figures were frequently seen. Similar but lesser numbers of neoplastic cells were seen in the parenchyma of liver, spleen, and the pancreas. Since the neoplasm involved several organs, we propose that the condition was of multicentric origin. Gross lesions, histopathologic findings and the organs involved differed from a previously described case of lymphosarcoma in a raccoon.PMID: 9359068 [PubMed - indexed for MEDLINE]""Lymphocytic leukemia and lymphosarcoma in a rabbit.Toth LA, Olson GA, Wilson E, Rehg JE, Claassen E.
Department of Comparative Medicine, University of Tennessee, Memphis 38163.Lymphocytic leukemia and lymphosarcoma were diagnosed in a rabbit with lethargy, emaciation, and pallor. The diagnosis was made on the bases of results of hematologic analysis, cytologic evaluation of a bone marrow specimen, and histologic examination. The lymphosarcoma was identified to be of T-cell origin. Leukemia is rarely diagnosed in rabbits, although lymphosarcoma is fairly common in this species.PMID: 2211315 [PubMed - indexed for MEDLINE]"
The only creature known to be immune to cancer are sharks and research is on to see why? that is as far as i know!
no they dont get cancer
Check out the research of Peyton Rous. His work in the early 1900s was on cancers in wild rabbits. Their cancer was attributed to Rous sarcoma virus.Monkeys can get cancers from the SV40 virus.Polluted rivers have produced fish with tumors.So, wild animals can and do get cancer.
