In 2017, over 22,000 Poles have been diagnosed with lung cancer. Incidence rates among men and women are 93 and 38 per 100,000, respectively, based on the European Standard Population (2013).1 Lung cancer ranks as the most prevalent malignancy overall, with approximately 18% of cancer cases among men and 10% among women. Lung cancer is also the main cause of cancer-related deaths in both sexes (almost 30% among men and 17% among women) and is the cause of almost 6% of all deaths in Poland. Similar to many European countries, tobacco epidemics was on the rise since the beginning of the 20th century and peaked in the early 1990s (Fig. 1).
