Lung cancer is a worldwide disease whose mortality rate is high with respect to other types of cancer. In cases of cancer, genetic mutations must occur so that the progenitor cell becomes neoplastic. Consequently, most cancers occur after the fourth decade of life. This stands for lung cancer, which is very uncommon in people aged less than 40 years. Some characteristics are peculiar of younger cases, including a high incidence of adenocarcinoma and a lower male/female ratio (1).
Studies have shown a direct relationship of tobacco smoking with this type of cancer. However, other risk factors described in the world literature, such as TBC infection, living in industrialized countries, and burning of oils, should not be forgotten.
Two cases are described in this report. Both patients are females without apparent risk factors diagnosed with lung cancer. They were intervened surgically and are currently undergoing chemotherapy.
