Elephants rarely get cancer – and the reason why could help humans

Elephants rarely get cancer – and the reason why could help humans

This is an Inside Science story.

(Inside Science) – “I’ve always been so enamored with elephants — one of the things that’s just amazing to me is that elephants have such an incredibly low rate of cancer. And it doesn’t make any sense that elephants have a low rate of cancer, because they’re so big and their cells are dividing so fast,” explains Matthew LaPlante, author of the book Superlatives: The Biology of Extremes.

For a long time, it was a mystery how elephants managed to grow so big without getting cancer, because every time a cell divides, there is a risk that it could mutate into a cancerous form. And it takes a lot of cell divisions for an elephant embryo to grow into a 13,000-pound animal.

“I mean, this is happening in a petri dish, but it’s really exciting. You have these cancer cells and when — they’re human cells, but they’ve been taught essentially to act like elephant cells would. And so, when a mutation happens that’s cancerous the cells, instead of reproducing, just kill themselves. For a really long time we figured like the way we’re going to have to fight cancer was one cancer at a time, because they’re very different. But this process appears to work for every kind of cancer that they’ve tried it on,” concluded LaPlante.
