Why elephants rarely get cancer

Cancer is just another mutation, but it's a mutation out of control that makes people sick and a mutation that kills people, and that makes it a problem for society. That mutation appears from different reasons, one of the being the chemicals that are in our air and our food - something that makes the cancerigens - and tere are some ways to avoid cancer (at least in some degress). There is also natural radioactivity, ultraviolet waves and viruses that can give people cancers, so there is no perfect protection yet from all of these factors.

Things like eating healthy, not smoking, have a good sleep and a good diet help a person the have a healtier longer life, and the evolution of food (as how it's made and as prices) makes that harder.

One interesting fact about elephants is that they're a lot less likely to get cancer than other animals (including us). Another interesting fact is that unlike most warm-blooded animals, their big testes are deep inside their bodies. It turns out, these two facts may be related.
