Since most thyroid nodules do not cause significant problems, the doctor may recommend regular follow-ups by physical examination and ultrasound tests to monitor the size of the nodules and function of the thyroid gland. The doctor may also prescribe medication as a part of thyroid hormone suppression therapy, although scientific evidence has been inconclusive as to its effectiveness in shrinking thyroid nodules. If the thyroid nodules are diagnosed to be causing hyperthyroidism, the doctor may also prescribe radioactive iodine or anti-thyroid medications to cause symptoms to subside.
Surgery may also be undertaken in cases where the nodule is so large that causes trouble breathing or swallowing, or where the nodules are found to be cancerous. However, surgery is done under general anesthesia and necessarily comes with the risk of complications.
Thermal ablation ( by either laser or radiofrequency) is an alternative method of treatment that is minimally invasive and has been proven to significantly reduce the volume size of thyroid nodules. According to published studies by Regina Apostolorum Hospital, Italy in 2003, patients experienced a 50% decrease in nodule volume size in six months, and a 60% decrease in two year, using Laser ablation. Another study by Dr. Baek from Asan Medical Centre, Korea in 2012 had showed that up to 90% reduction in the volume of the thyroid nodule can be achieved at 6 months, using radiofrequency ablation. Thermal ablation, using laser or radiofrequency, is a relatively safe procedure as there is no need for general anesthesia and complications are rare. Normal thyroid tissue is preserved during the treatment and the risk of hypothyroidism after treatment is very low.
