Thick phlegm, smokers, lung ciliary epithelial cells are already damaged, cleaning ability and immune protection function are reduced, and the incidence of lung infection is relatively high.

Is there any blood in the cough sputum? Do you have a family history of lung cancer or any other family?

Personally, I don't think you have any problems, if you want to confirm the diagnosis and do a needle biopsy, you should have a subpleural nodule that should be more hopeful.

I'm just a little chest tightness and shortness of breath cough now, but the doctor said it has nothing to do with this, I'm scared.

The doctor said it was okay if it didn't matter.

Pay more attention to yourself.

If such a nodule is found, bronchoscopy or CT-guided percutaneous lung puncture should be further refined to clarify the nature of the nodule ride. If it is a nodule formed by pure cancer of the lung in the early stage, surgery should be performed to remove the lesion in time. If it is a ground-glass nodule caused by pneumonia, there is usually fever, cough, yellow sputum, and increased white blood cells, and the nodule can be absorbed through active anti-inflammatory and anti-infection**.

It is also possible that the ground-glass nodules caused by the invasion of the lungs by Mycobacterium tuberculosis bacilli, there will generally be low-grade fever, night sweats, and fatigue in the afternoon.
