A thyroid nodule is a growth or lump in the thyroid gland, and many are benign.
Many thyroid nodules cause no symptoms, but some are noticed as a neck lump, pressure when swallowing, hoarseness, or symptoms related to thyroid hormone imbalance.
Ultrasound helps when a thyroid lump is felt, when blood tests suggest thyroid disease, or when doctors need to decide whether biopsy or follow-up is appropriate.
Ultrasound helps assess the nodule's size and appearance and can guide fine needle aspiration when needed.
Some nodules are simply monitored, while others need biopsy, endocrine review, or surgery depending on their features and lab context.
This entry explains the finding. The next step is having a radiologist interpret your specific scan, not a general definition.
