Lung cancer is often closely linked to smoking. a recent study found that one in four smokers with specific gene defects will have lung cancer.
Chairman of the study, Richard Houlston, professor of molecular and population genetics at the Institute of Cancer Research in the UK said that smokers generally have an increased risk of lung cancer by 15 percent, this value is much higher compared with nonsmokers. However, in smokers who have a gene defect, the risk increased by 10 percent, to 25 percent.
