Lung Nodule on CT
A small spot on the lung is usually benign — but always needs a plan.
Routine health-check CT scans increasingly turn up small, unexpected lung nodules. Most nodules under 8 mm are benign — but each one needs a structured plan rather than a wait-and-see approach.
We follow international (Fleischner Society) guidelines and offer Radial EBUS for safe sampling of peripheral nodules without open surgery.
Symptoms we look out for
- Usually no symptoms — found incidentally on imaging
- Occasionally a persistent cough, blood in sputum, or weight loss in higher-risk nodules
Diagnostics we offer
Our treatment approach
- Risk stratification by size, density, shape and your smoking history
- Surveillance CT at the right interval (3, 6 or 12 months) for low-risk nodules
- PET-CT and tissue diagnosis for nodules >8 mm or with suspicious features
- Multidisciplinary referral when malignancy is confirmed
Common questions
I was told my nodule is 5 mm and to repeat the CT in a year — is that safe?
Yes. A 5 mm nodule in a low-risk patient has a very low chance of being cancer, and the recommended follow-up is exactly that — a repeat scan to confirm stability.
Will I need surgery?
Most patients do not. Radial EBUS, CT-guided biopsy and PET-CT can answer the question without surgery in the majority of cases.
