Hi, welcome to HCM.
Lymhnodes are draining sites for any pathology in lungs. They are situated in central part of lung known as mediastinal region. If your physician is telling that there are enlarged lymphnodes
, then he nay be thinking for any underlying pathology in lungs.
It will be better if you take opinion from radiologist
for the same xray. Also it is only significant if you have any symptoms like cough, fever
, chest pain
, weight loss
, breathlessness. Otherwise no need to worry. Just for fitness purpose you can go for more xrays.
Hope I have answered your query.
