Lung nodules are usually old foci left over from previous lung diseases, which need to be treated as soon as they are found.
Lung nodules are old lesions that appear after a series of repairs to lung tissue damage caused by lung disease, and may appear as nodular lesions in the lungs, with a hard texture, and the center of the lesion is usually inactivated or dead cells, while the lesion is surrounded by macrophages and lymphocytes in the form of nodules.
Lung nodularity is a common benign lung lesion, usually associated with fibrous tissue proliferation, which is more dense on CT and does not require specific treatment.
