Nodule

A nodule is a small, rounded mass or lump that can develop in various tissues, often indicating an abnormal growth. In medical contexts, nodules can be found in the lungs, thyroid, or skin and may vary in significance from benign to malignant. They can also occur in geology, where they refer to compact lumps of mineral matter embedded within a rock. Nodules often require monitoring or biopsy to determine their nature and associated risk.
