DNA repair plays a critical role in protecting the genome of the cell from the insults of cancer-causing agents such as those found in tobacco smoke. Reduced DNA repair capacity would, therefore, constitute a significant risk factor for smoking-related cancers. Recently, a number of polymorphisms in several DNA repair genes have been discovered, and it is possible that these polymorphisms may affect DNA repair...
