A single genetic mutation made humans more susceptible to cancer

Since we split from chimpanzees, a single letter change in our DNA appears to have made us more likely to get cancer, possibly as a trade-off for extra fertility

A tiny change in our DNA that occurred after we evolved away from other primates has made us more prone to getting cancer, new research suggests.

Cancer is relatively rare in other primates. For example, autopsies of 971 non-human primates that died at Philadelphia Zoo in Pennsylvania between 1901 and 1932 found that only eight had tumours.
