Order in which cancer-driving mutations occur affects the chance of tumour development
Nature, Published online: 03 December 2025; doi:10.1038/d41586-025-03748-4What happens to the thousands of intestinal cells that have tumour-initiating DNA mutations? A study in mouse models shows that most are eliminated by strong negative selection, but those that survive create a more-permissive environment for subsequent mutations, opening up routes for cancer to develop.
