Lung cancer is the leading cause of cancer death worldwide. People at risk for lung cancer who get screened are likely to catch 80% of lung cancer at an early stage when it is most curable.* Computed tomography (CT) screenings are the best tests doctors have to find lung cancer early. The U.S. Preventive Services Task Force (USPSTF) recommends annual screening for lung cancer in adults aged 50 to 80 years who have a history of smoking two packs a day for 10 years and currently smoke or have quit within the past 15 years. The Lung Cancer Screening Program offers seamless referral to the Stanford Medicine Cancer Center if treatment is needed. *According to the American Lung Association
