Pulmonary Nodule

What is a pulmonary nodule?
A pulmonary nodule is a round or oval-shaped growth in the lung. You might also hear it called a “spot on the lung”, “coin spot” or “coin lesion”.  A pulmonary nodule is usually 3 centimeters or smaller in diameter, has a smooth edge, and is solid in appearance. 

What causes a pulmonary nodule?
A pulmonary nodule can be caused by an infection, inflammation, or an old scar. You might hear the term granuloma.  A granuloma is a growth that is caused by inflammation. The inflammation can either be a result of a previous infection or a disease that is non-infectious (rheumatoid arthritis, sarcodosis, etc).  Most of the time, a pulmonary nodule causes no symptoms and requires no treatment.

Does this mean I have cancer?
Greater than 90% of pulmonary nodules less than 2 centimeters are non cancerous.

What happens next?
A repeat low dose CT chest is recommended based on the size of your nodule.   If your pulmonary nodule does not get bigger in 2 years, then it is most likely not cancer.  You will be notified of that information, if needed.  This is based on National Comprehensive Cancer Network guidelines (NCCN).  (LINK)
