A recent study by the Wildlife Conservation Society (WCS) says that cancer is a major threat to wild animal populations as well.
A newly published paper in the July edition of Nature Reviews Cancer compiles information on cancer in wildlife and suggests that cancer poses a conservation threat to certain species. The WCS authors highlight the critical need to protect both animals and people through increased health monitoring.

In certain situations, cancer threatens the survival of entire species. The Tasmanian devil, the world's largest carnivorous marsupial, is at risk of extinction due to a cancer known as devil facial tumor disease. This form of contagious cancer spreads between individual Tasmanian devils through direct contact (primarily fighting and biting). To save the species from this fatal disease, conservationists are relocating cancer-free Tasmanian devils to geographically isolated areas or zoos.
