The quick guide

What it means: A fast-growing lung cancer, almost always linked to smoking. Doctors describe it as limited stage (one side of the chest, treatable with one radiation field) or extensive stage (spread further).

How it's found: Biopsy plus scans, including a brain MRI.

How common it is: About 13 to 15% of lung cancers.

How treatment works

🌱 Early-stage

Limited stage: chemo (cisplatin or carboplatin with etoposide) given together with chest radiation; very small tumors may have surgery. Durvalumab after chemoradiation is an option. Brain radiation or MRI checks may follow.

🔁 Advanced or metastatic

Extensive stage: chemo plus immunotherapy (atezolizumab or durvalumab), then immunotherapy maintenance.
Later options include tarlatamab, lurbinectedin or other chemo, and clinical trials.

Approvals depend on stage and prior treatment. Your care team will decide what fits you.
