Not too surprising in theory. During development, the body requires very fast growth. Very fast growth increases the chance of mutations. If the selective pressure to develop quickly diminishes, then I would expect that uncontrolled growth (cancer) would be less likely as well. It would be interesting to see if this is observable in other animals (those with the shortest development times, which require the fastest bursts of growth, should be at higher risk for cancer or should have evolved solutions like extra telomerases).
