There is a corellation between beeing hunted by a predator (external death stimulus) and not beeing hunted by a predator (internal death stimulus). Predators life a dangerous life, for them theire daily activity is a eds.
Obviously the benefits of cancer suppressing DNA in a population apply only if you are either to well hidden (naked mole rat, sloth) or to big to be predated (Rhino, Elephant, Whale).
Sorry, we as humans are part of a predatable species, so live fast and leave a devourable corpse for your descendants to mourn was our main strategy. If in search for human compatible cancer avoidance, the biggest interest should be on the most well hidden monkey - or the biggest (silverback).
Interesting is also how the re-productive cycle factors into this. If a individual takes a long time to grow up- cancer is a selector tortoises, if the reproduction is fast (mice/birds) cancer is basically not important. If every mice would get cancer after year 2 - the species still would continue.
