The main cause of lung cancer is cigarette smoke. Several studies indicate that there is a clear dose-effect relationship between inhaling tobacco and development of lung cancer.
Studies report that the risk of having lung cancer is 14 times higher among smokers than non-smokers (up to 20 times for heavy smokers, e.g. 20 cigarettes per day).
Cigarette smoke is responsible for the vest majority of lung tumors.
Air pollution, family history of lung cancer, as well as various pathological conditions affecting the normal lung physiology may also contribute to increase the possibility of being affected by this disease.
THE CONTINUOUS MONITORING OF A GENETIC MUTATIONAL PROFILE
Smokers, or people at risk of developing lung cancer, can undergo a yearly checkup of their mutational profile to monitor the potential onset of lung cancer.
