Elephants have 100 times more cells in their bodies than humans, which should make them far more vulnerable to cancer than we are. But less than 5 percent of elephant deaths are linked to cancer, which researchers credit to the animals’ abundance of cell-suppressing genes -- genes that might represent the next step forward in the fight against cancer.
