Why Do Thyroid Nodules Occur? | Diagnosis & Non-Surgical Treatments

RIVEA Vascular Institute | 03 April 2026

The thyroid gland plays a vital role in regulating metabolism. Thyroid nodules are common and may appear as a swelling in the neck, sometimes causing discomfort or difficulty swallowing.

Diagnosis typically involves ultrasound and, if required, FNAC to determine whether the nodules are benign or cancerous.

While surgery has been the traditional treatment, minimally invasive options such as Radiofrequency Ablation (RFA), Microwave Ablation, and Thyroid Artery Embolization are now available. These treatments reduce nodule size safely, often as day-care procedures with quicker recovery.
