New view of cancer: 'Epigenetic' changes come before mutations

...eased tumor evolution. Many of the properties of advanced tumors, including the ability to spread, or metastasize, are inherent properties of the progenitor cells that give rise to the primary tumor, Feinberg notes. These properties do not necessarily require other mutations to occur. "Greater attention ...
