Most lung neoplasms are no cause for worry, but they should all be checked by a healthcare professional, such as an oncologist (cancer specialist), pathologist (doctor who examines tissues in a lab), and pulmonologist (lung specialist), to make sure that it is not cancerous, especially if you are a former smoker or have a nonsmoking first relative with lung cancer..
