Nodular density mass in lung
My doctor found a nodular density mass that measures 17mmx7mm in my lower right lung. I have had two scans within 6 months and there has been no change. I am supposed to have another scan in 3 months to make sure that there is still no change.
My question is what are the possible causes of this mass and how long should I continue to have these scans if there is no change? When I asked my doctor he said it is nothing to worry about but would not ellaborate.
A lung mass can represent a variety of processes, from insignificant to severe. The list of causes is long. The level of suspicion for a severe problem, particularly lung cancer, depends on a number of factors including, personal risk (smoking, family history, age), characteristics of the mass on CT scan, and growth. Common non-malignant causes include a granuloma (type of scar) from prior histoplasmosis infection, scar from a prior pneumonia, and hamartoma (a benign congenital nodule).
If it is stable, there is less to worry about. However, if you are concerned, an option would be to seek a second opinion from a pulmonary specialist, such as a pulmonologist or a thoracic surgeon.
