Research ties disease to specific mutations
(NEWSER) - Scientists have mapped the genomes of skin and lung cancer, allowing them to know which specific mutations cause the disease. The development, hailed as a major breakthrough, could lead to earlier detection and better drug treatments. Melanoma and lung cancer are triggered by sets of tens of thousands of errors, mostly caused by overexposure to the sun and cigarette smoke, respectively. One researcher likened the process to Russian roulette—"Most of the time the mutations will land in innocent parts of the genome, but some will hit the right targets for cancer." More»
