What are Thyroid Nodules?
Thyroid nodules are abnormal growths within the thyroid gland. While most nodules are benign, they can occasionally be cancerous and should be monitored.
Symptoms of Thyroid Nodules
Most people with thyroid nodules do not have any noticeable symptoms. However, some people may feel a lump in their throat, develop difficulty swallowing, or experience hoarseness.
Causes of Thyroid Nodules
Nodules may develop for various reasons, including:
- Biopsy of the neck
- Congenital hypothyroidism
- Exposure to radiation
- Hormonal imbalances
- Genetic syndromes
- Hashimoto’s thyroiditis
Diagnosis of Thyroid Nodules
If your doctor suspects you have thyroid nodules, he or she may order a physical exam, blood test, ultrasound, or biopsy.
Treatment of thyroid nodules depends on their size and whether or not they are cancerous. Small, noncancerous nodules can generally be left alone and monitored by an experienced physician. Larger nodules may require surgery or other forms of treatment.
