  • The effect of radon. This gas is in the soil, in the basements and first floors of homes. Radiation from radon contributes to the development of mutations in cells of the respiratory tract, including the lungs.
  • Genetic predisposition. In the presence of lung cancer among blood relatives the likelihood of developing this disease increases.
  • His advanced age. Physiological aging of the body reduces its resistance to malignant processes.
  • Professional activities. The likelihood of developing lung cancer is higher among representatives of professions related to exposure to fugitive dust-producing carcinogens. This, for example, asbestos, cadmium, chromium, arsenic.
