'Patchwork' tumors prevalent across multiple cancer types
E-Mail Researchers at the Francis Crick Institute, as part of an international collaboration of scientists through the Pan-Cancer Analysis of Whole Genomes Consortium, have analysed the whole genomes of tumour samples from over 2,600 patients with different types of cancer. They identified a high prevalence of genetic diversity within individual tumours, which they further characterised. Their findings confirm that, even at late stages of development, tumour evolution is driven by changes that benefit the cancer. When cancer cells divide, errors occur in the process of copying their DNA. T...
