Thyroid nodules
- Symptoms
Most thyroid nodules do not cause symptoms. Thus, most people may only realize they have a thyroid nodule when it is large enough to be noticed in the mirror, or found by chance during a physical examination, or incidentally picked up on investigations like ultrasounds, CT scans or
PET scans.
Sometimes, bleeding into a thyroid cyst or nodule may cause a sudden painful swelling in the neck. Occasionally, advanced thyroid cancer may cause a hoarse voice or difficulty swallowing.
