What is the primary indication for lung cancer screening with low dose CT scans?

• A. Aging population
• B. Family history of cancer
• C. High risk due to smoking history
• D. Asthma diagnosis

Answer: (C)

The primary indication for lung cancer screening with low dose CT scans is high risk due to smoking history. This is grounded in extensive research indicating that individuals with a significant history of smoking are at a much higher risk of developing lung cancer. Low dose CT scans have been shown to effectively detect lung cancer at earlier stages in this at-risk population, allowing for timely intervention and treatment, which can significantly improve outcomes. While an aging population is a factor in the overall incidence of lung cancer, it is not a specific criterion for screening. Family history of cancer can certainly contribute to an individual's risk profile; however, the major risk factor that drives lung cancer screening protocols is smoking history. Asthma diagnoses are unrelated to lung cancer risk and do not impact the decision to conduct lung cancer screenings. Therefore, focusing on those with a significant smoking history is critical in identifying high-risk individuals who would benefit most from screening measures.
