A thyroid nodule is a small lump that forms in the thyroid gland, located at the front of your neck. These nodules can vary in size and are often discovered during routine check-ups.
Thyroid nodules are very common. More than half of adults may develop them, especially after the age of 50, however some nodules needs investigation.
They can develop from normal thyroid tissue growth, fluid-filled cysts, thyroid inflammation, but could also be thyroid cancer.
Many nodules do not cause symptoms. If symptoms occur, they may include a lump in the neck. Depending on the size and location of the nodules it can cause difficulty swallowing, hoarseness, and sometimes even signs of an overactive thyroid such as weight loss or fast heartbeat.
Most thyroid nodules are benign, but approximately 7–15% can be cancerous. It's important to have them evaluated by a specialist.
Doctors usually do a neck exam, an ultrasound scan, thyroid blood tests, and sometimes a fine needle aspiration (FNA) to test the cells.
The treatment for thyroid nodules depends on their type. Options include monitoring with scans, surgery, medications or radioactive iodine for overactive nodules. Our specialists will recommend the best approach for your condition.
See a doctor if you notice a new neck lump, if the lump grows quickly, causes swallowing or breathing problems, or if you have a family history of thyroid cancer.
