Why the Elephant Didn’t get Cancer:

Follow my logic here: cancer occurs due to mutations in your cells. Elephants have A LOT more cells than people do. Therefore, elephants should have more cancer than people.

p53 heatshock proteins, known in some circles as the “Guardian of the Genome” (soon to be a Marvel movie I’m sure), are one of the key tumor suppressing genes. Humans have 2 genes for p53 proteins. Elephants have 38.
