Lung cancer is the first cause of death in patients with tumor disease. Although smoking is the first risk factor, other factors (environmental, occupational, dietary and genetics) can also contribute in its development. Clinical symptoms frequently go undetected until the disease is advanced. The capacity of annual Low-dose spiral computed tomography (CT) screening to reduce lung cancer mortality in high-risk patients is nowadays a field of great interest. In the last years, lung cancer treatment has improved dramatically, both in early stages of the disease, based on new techniques of radiotherapy in inoperable patients, as in the case of metastatic disease, with the discovery of molecular markers enabling a targeted and individualized therapy.
