Skin is a battlefield for mutations

Normal skin contains a patchwork of mutated cells, yet very few go on to eventually form cancer and scientists have now uncovered the reason why. Researchers genetically engineered mice to show that mutant cells in skin tissue compete with each other, with only the fittest surviving. The results suggest that normal skin in humans is more resilient to cancer than previously thought.
