Why do elephants rarely get cancer ? With their bodies having a hundred times more cells than humans, you'd think that they would be a hundred times more likely to see the development of cancerous cells. But that's not the case. In fact, studies show that fewer than 5% of the animals die of cancer, compared with up to a quarter of humans.

There could be some interesting repercussions for cancer research. Dr Joshua Schiffman is an oncologist at the University of Utah School of Medicine in the US.
