After successful treatment of pulmonary tuberculosis (TB), it is common for small scars and calcium deposits to form in the lungs. This is called post-tuberculosis lung calcification. It means your body has healed after fighting the TB infection.
Why Does This Happen?
When TB bacteria infect the lungs, your immune system builds tiny walls (granulomas) to trap them. Over time, these granulomas heal and may become hard and calcified. On a chest X-ray or CT scan, these healed spots show up as small white areas — often called Ghon focus or Ranke complex.
Are These Lung Calcifications Dangerous?
No. In most cases, these calcified spots are harmless.
They do not mean you still have active TB.
Most people with these spots feel completely normal and have no symptoms.
They do not turn into lung cancer.

How Will I Know If I Have Them?
Your doctor may see these spots on a routine chest X-ray or scan.
They appear as small, round, white marks in your lung tissue or nearby lymph nodes. Sometimes, there may also be mild scarring or thickening on the lung lining (pleura).
Do I Need Any Treatment for Post-TB Lung Calcification?
No special treatment is needed for these old, healed TB spots.
You do not need antibiotics or surgery for them.
Regular follow-up scans are usually not needed, unless you develop new symptoms.
When Should I See a Doctor Again?
Although old calcified TB spots are inactive, you should always watch out for signs of new lung problems. See your doctor if you have:
A cough that lasts more than 2 weeks
Coughing up blood
Fever, night sweats, or unexplained weight loss
Chest pain or breathing difficulty
How to Keep Your Lungs Healthy After TB?
Complete your full TB treatment if you ever have TB again.
Avoid smoking — it damages your lungs and increases infection risk.
Eat a balanced diet and stay active to keep your immune system strong.
Visit your doctor for check-ups if you have other lung issues.
Key Takeaway
Post-tuberculosis lung calcification means your lungs have healed after TB.
It is common, not dangerous, and does not need treatment.
If you ever have new symptoms, talk to your doctor early.
