Key points from article :
Naked mole-rats are near immune to cancer.
So far this resistance has been put down to greater efficiency in cancer suppression genes.
Alpha-2-macroglobulin (A2M) appears to inhibit tumor growth in multiple mammalian species.
Naked mole-rats have a very high level of A2M in their tissues.
Older humans exhibit lower levels of A2M than their younger counterparts.
The study was published in the Plos ONE journal.
