ELI5: If cancer is caused by your cells making errors when they duplicate, won't all multi-celled organisms, provided they live long enough, eventually get cancer?

Holy shit, front page!

By sheer statistical probability, yeah. 

There are organisms like naked mole rats that have numerous barriers to tumor development that enable them to resist cancer so well that we've never documented it in the species. However, *eventually* we would expect there to be mutations in enough of the genes that prevent tumor formation for one to form. DNA replication and DNA maintenance can't be 100% perfect.
