When should I consider getting a lung cancer screening and what does it involve?

Lung cancer screening with low-dose computed tomography (LDCT) is recommended for adults aged 50-80 who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years.

The Screening Process

• Duration: The scan takes approximately 30 seconds
• Preparation: No fasting required, wear comfortable clothing without metal
• Radiation: Very low dose, equivalent to about 1.5 millisieverts
• Results: Usually available within 1-2 weeks

What Happens After

• Normal results: Continue annual screening
• Suspicious findings: Additional imaging or biopsy may be recommended
• False positives: About 25% of initial screenings show nodules that are benign

Early detection through screening can reduce lung cancer mortality by up to 20% in high-risk populations.
