A lung nodule is a small mass of dense tissue on the lung. So, what happens after a physician discovers a lung nodule? There are many steps that help medical teams gather more information about the nodule and a patient’s health. One important step is staging. Visit our resources to learn more about what goes into discovering, diagnosing staging and treating lung nodules at Lung.org/lung-nodules or Lung.org/staging. Accurate staging leads to more precise treatment. Ask questions and work with your care team to learn what to expect next. Support for this video was made possible by Olympus.
