What Are the Causes of Nodules in the Lungs?
A lung nodule is a small mass of abnormal tissue growth in the lungs. The nodules can be generally divided into benign or malignant lesions, but there are many causes for their presence in the lungs. The majority of lung nodules are benign, but the website LungNodules Organization indicates that approximately 40 percent of the lesions are malignant. Even if a lesion is benign upon initial testing, practitioners will monitor continually to check for changes in appearance that can signify malignant transformation.
