nodule - (mineralogy) a small rounded lump of mineral substance (usually harder than the surrounding rock or sediment) mineralogy - the branch of geology that studies minerals: their structure and properties and the ways of distinguishing them.
The nodule is small, has a smooth border, and has a solid and even appearance on an x-ray or CT scan. You are young and do not smoke. Your doctor may then choose to just watch the nodule on x-rays. Repeat chest x-rays or chest CT scans are the most common way to follow the nodule. Sometimes, lung PET scans may be done. If repeated x-rays show that the nodule size has not changed in 2 years, it is most likely benign and a biopsy is not needed.
