Thyroid Nodule

📖What is Thyroid Nodule?

A thyroid nodule is a discrete lump or growth within the thyroid gland that can be solid or fluid-filled, and is a common finding often detected incidentally during a physical exam or imaging performed for another reason. The vast majority of thyroid nodules are benign, arising from colloid accumulation, cysts, or benign adenomas, but a small percentage represent thyroid cancer. Most nodules do not cause symptoms unless they grow large enough to be visible or press on surrounding structures like the trachea or esophagus. Evaluation focuses on distinguishing benign nodules from those requiring further workup or removal.
