Thyroid Nodules

Thyroid Nodules are common and often detected incidentally during physical examination or imaging studies. Most nodules are benign, but a small percentage may represent Thyroid Cancer, making proper evaluation essential. These nodules may be solid, cystic, or mixed in composition and can vary in size.

Many thyroid nodules do not cause symptoms. However, larger nodules may produce visible neck swelling, difficulty swallowing, throat discomfort, or voice changes due to pressure on nearby structures. Some nodules become overactive, producing excess thyroid hormones and leading to Hyperthyroidism, which causes weight loss, palpitations, and anxiety.

Diagnosis involves thyroid function tests, ultrasound imaging, and fine-needle aspiration cytology (FNAC) to assess malignancy risk. Most benign nodules require only observation and periodic monitoring. Treatment is recommended if nodules are cancerous, suspicious, large, or causing compressive symptoms. Options include surgical removal (thyroidectomy), radioiodine therapy, or minimally invasive procedures.

Early detection and appropriate management help prevent complications and ensure optimal thyroid function, supporting overall metabolic balance and long-term health.
