According to the Seattle Cancer Care Alliance, lung, or pulmonary, nodules have numerous causes, including fungal or bacterial infection, sarcoidosis, lymphoma, lung cancer and cancers metastasized from other organs. The Mount Sinai Beth Israel Lung Nodule Center adds that medical conditions that cause swelling, thickening and scarring of pulmonary tissues, such as healed pulmonary infarcts and chronic bronchopneumonias, can also cause lung nodules.
