Lung cancer screening guidelines

Lung cancer screening is recommended mainly for current or former heavy smokers aged 50 to 80 who have a significant smoking history (about 20 pack-years). It involves a low-dose CT scan to detect lung cancer early, before symptoms appear. The goal is to catch cancer sooner, when treatment is more effective. Screening is generally advised annually if you meet these criteria and are in good health. It's important to discuss individual risk factors and screening benefits with your healthcare provider to determine if it's appropriate for you.
