The risk of lung cancer in smokers dependent genes

Scientists have genetic variations that could contribute to an increased risk of lung cancer in smokers and ex-smokers. Three research teams have published their research in the journals Nature and Nature Genetics. Each team identified a genetic variation in two regions of chromosome 15, which are often found in people, but also the risk for those who smoked or smoke, experts say. Approximately 15% of the total number of current and former smokers in the presence of two copies of the genetic changes that are inherited, one from each parent, increases the risk of lung cancer by 70-80%. If there is only one copy inherited genetic changes that increase the risk of lung cancer by 28%. Lung cancer caused by tobacco dependence is 80% of lung cancers. Smokers have an average risk of lung cancer is 10%, compared with 1% in people who have never smoked. Scientists believe that they hope is a very important step has identified people with an increased risk for lung cancer, and that this will help. The occurrence of diseases
