Countless pulmonary nodules are found each year during chest X-rays or CT scans. Most nodules are noncancerous (benign). A solitary pulmonary nodule is found on up to 0.2% of all chest X-rays films. Lung nodules are more commonly found on more sensitive scans such as lung CT scans, where they are discovered upto 50% of the time. Risk factors for malignant pulmonary nodules include a history of smoking and older age.
