Thanks for your question on Healthcare Magic.
I can understand your concern.
I have gone through the CT report you have mentioned.
Term 'mm' means millimeters.
You are having Calcified lymphnode and nodule. Calcification means old healed lesion.
Chronic
cigarette smoking can cause calcification. It can also cause similar emphysema. So your CT report is suggestive of early lung damage caused by the cigarette smoking.
So you should quit smoking as soon as possible.
To know the severity of emphysema, PFT (Pulmonary Function Test) is must.
If PFT is showing obstructive defect then you should start inhaled
bronchodilator (formoterol or
salmeterol) and inhaled corticosteroid (ICS) (
budesonide or
fluticasone).
Don't worry, you will be alright but first quit smoking.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
