Low-Dose CT Lung Cancer Screening in India
Quick answer
Low-dose CT screening uses reduced-radiation CT to look for small lung nodules in heavy current or former smokers. Finding lung cancer early improves treatment options. It is for people meeting age and smoking criteria, not for everyone, because false alarms are common.

Frequently asked questions
What if a nodule is found?
Most nodules are harmless. Small ones are usually checked with a repeat scan later.
Is it worth screening if I have never smoked?
Routine screening is not generally recommended for non-smokers. Discuss specific risks with a doctor.
How is it different from a normal chest CT?
It uses much less radiation and no contrast. It is designed for screening, not detailed diagnosis.
