Of course, but if it's possible in one mammal, there's no real reason why it shouldn't be possible in another. I highly doubt that our vulnerability to cancer is somehow intrinsic to what makes us human.

This is obviously far off, but genetic modification opens up a whole new world of possibilities.

Maybe we should tell the scientists then. Apparently they've been doing it wrong for all these decades...

Naked mole rats aren't even rats, per se - they are the only species in its genus and the only known eusocial mammal. (I wonder if E. O. Wilson studied them?)
