The key to discovering a cure to cancer? Scientists say it could be inside elephants.
Researchers say elephants have an "army of tumor-fighting proteins" in their bodies that seek out and destroy mutated cells.
That gives them an exceptionally high resistance to cancer - more than five times greater than that found in humans.
Scientists are still figuring out how to apply these proteins to a cancer cure - but say it proves the importance of preserving elephant populations and habitats.
