Just a hypothesis I thought of:

A lot of cancer cells are developed because of constant background radiation, if you get older you just were exposed to more of it.

Elephants have a much higher volume to be affected by it, so just from an evolutionary perspective they had to develop a better resistance. The ones who got cancer early couldn't reproduce as well.

Does that make sense? Or does the article say exactly that?

Why not have a read and find out?

Validating your hypotheses? How quaint!

Well it just says many cells should mean a lot of cancer.

We are not even sure if we need a certain amount of background radiation.
