A nodule is a small rounded or irregular area seen in tissue, commonly in the lungs, thyroid, liver, or elsewhere.
Many nodules cause no symptoms and are found incidentally, though some can be linked to a lump, cough, pressure symptoms, or organ-specific complaints depending on where they are.
Imaging helps show the nodule's size, edges, density, and change over time, which are important for deciding whether it is likely benign or needs closer follow-up.
Imaging helps assess size, shape, density, and change over time, which all help determine how concerning it may be.
Some nodules are watched with follow-up scans, while others need biopsy or specialist review depending on the pattern and context.
