Do you have history of smoking?
Family history of lung cancer?
I never smoked nor have I been around smoke, my grandfather died of lung cancer because he smoked(cigarettes and cigars) all his life since teenager. Nobody else and no other cancer in my family.
Thank you very much for the useful information.
With a negative history of smoking; and the fact that none of your parents had it, its extremely unlikely that this nodule represent a lung cancer.
Moreover you did not lose any weight; and do not have other symptoms suggestive of lung cancer such as coughing out blood (hemoptysis).
Infact in over 99% of the cases, such pulmonary nodules turn out to be of benign nature. This simply represent a calcification, granuloma, or an old healed lesion from a previous chest infection.
Therefore, stay relaxed and do not panic.
At your age the possibility of cancer is least likely; with no symptoms suggestive of cancer, no history of smoking, the chances are almost negligible.
To be absolutely sure about this, your doctor may order a CT scan of the chest which will rule out any serious possibility like a cancer, and will help put your mind at ease.
