Present-day relevance
Lung cancer begins in the tissues of the lung. The two broad groups are non-small cell lung cancer (the most common) and small cell lung cancer. Low-dose CT screening is recommended for certain adults with a significant smoking history, within an age range set by guidelines. Whether screening is appropriate depends on individual risk and is decided with a clinician.
