Interestingly, those mammals that are highly resistant to cancer (such as bats or whales), tend to be resistant against all cancers at once, for decades. Maybe a stronger immune system, such as the bats have - it is really incomparable to humans - can whack cancer cells reliably regardless of their particular genetic signature. Much like it can kill various germs without analyzing their DNA/RNA first.
