How Sun and Smoke Trigger Cancer
December 21st, 2009
Smokers may develop a mutation for every 15 cigarettes smoked, according to new analysis of the genome of a tumor from a lung cancer patient. By comparing the patient’s normal genome sequence to the sequence of the tumor, scientists at the Wellcome Trust Sanger Institute, in London, found that the tumor cells had acquired more than 23,000 mutations, according to research published in Nature on Thursday.
