Lung cancer is the leading cause of cancer-related death worldwide, with NSCLC accounting for 85% of all lung cancers 2. Lung adenocarcinoma has the highest incidence among lung cancer patients, with a sex-specific incidence of about 30% in men and 37% in women in the United States 3. The strongest risk factors for lung cancer are tobacco use and age, although small-cell lung cancer and squamous cell lung cancer have a stronger association with tobacco use than does lung adenocarcinoma 3. A cancer diagnosis is most often unexpected because cancer typically doesn´t cause signs and symptoms in its earliest stage especially lung cancer. Young adults are often misdiagnosed due to the misconception that cancer is an "older person´s disease". Although lung cancer has a low survival rate, early detection and treatment allow patients increase years of survival. The presence of cancer of the lungs is rare in adolescent patients, particularly in those under 20 years of age. A cancer that begins in the lungs is most often found in older patients with a history of tobacco use. Many people think of lung cancer as a disease of older people, but lung cancer does occur in young people.
