Special genetic mutation protects some people, the lungs from damage and cancer, according to scientists from the University of Nottingham. They conducted a study involving 50 thousand patients with obstructive pulmonary disease (COPD). Most of the patients smoked at the time of the study or give up bad habits after diagnosis.
Because tobacco smoke narrows the bronchial lumen. The result is coughing, discomfort in the chest area. COPD is a disease of smokers, 80% of all patients with COPD was Smoking.
Scientists were able to isolate a series of mutations that protect the lungs from damage by tobacco smoke. Cells of the lung tissue, such people recover quickly and regenerates. The researchers say that if these people didn't smoke, their respiratory system work even better.
