Hi,
How are you? What other symptoms are present? Lung nodules or small masses of tissue in the lung and may be brought about by infections, such as histoplasmosis or tuberculosis, hamartoma, lung cysts, and vascular abnormalities. Smaller nodules may be harmless but may require monitoring for any changes in size and appearance. Comparison of chest X-ray or CT scan with a previous one may also be done.Additional tests such as  CT scan, positron emission tomography (PET) scan, bronchoscopy or tissue biopsy  may also be performed to rule out malignancy. It is best that you discuss the results with your attending physician for proper evaluation. Take care and do keep us posted.
