A nodule is a small mass of tissue which forms in or on the body, usually in response to injuries. Nodules are typically hard and they can be easily felt. For the most part, the masses are benign, requiring no medical action, but sometimes they can interfere with the function of the body, or they may be malignant.
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.
