  • Lung cancer is the leading cause of cancer death in the United States (US).
  • More than 80% of lung cancer deaths are attributed to tobacco use highlighting the importance of primary prevention.
  • A US trial showed that screening high-risk patients with low-dose computed tomography scans reduced lung cancer mortality by 20% compared with chest radiography.
  • The US Preventive Services Task Force recommends annual lung cancer screening for high-risk patients (30 pack-years, current or quit within 15 years) aged 55 to 80 years.
  • The Centers for Medicare and Medicaid will cover screening but requires programs to engage patients in shared decision-making, offer smoking cessation, and report data to a central registry.
