What is a Thyroid Nodule ? How is it Detected ?

Thyroid Nodule ? How is it Detected ?


A thyroid nodule refers to the formation of lumps or growths within the thyroid gland. It is quite common in the population, with an occurrence rate of about 50% in adults, meaning one in two people may have one. It is especially more prevalent in women and smokers. Thyroid nodules usually do not cause symptoms or complaints and are generally not detected unless they grow beyond a certain size.

During a physical examination, nodules are typically detected when they reach a certain size. The increasing use of imaging techniques such as ultrasound and computed tomography (CT) and more frequent health checkups have led to an increase in detection rates. They can be easily identified using thyroid ultrasound. Once a nodule is detected, further investigations, including blood tests, are conducted to determine whether the nodule is producing hormones (toxic or non-toxic nodule).

What Does Multinodular Goiter Mean ?


A thyroid nodule can be solitary (one) or multiple. When a person has two or more thyroid nodules larger than 1 cm, it is referred to as multinodular goiter. Each nodule is evaluated separately using ultrasound. Nodules are classified based on their appearance in the ultrasound images.

What Happens After a Thyroid Nodule is Detected? How is it Monitored ?


Thyroid nodules are typically detected following an ultrasound or a physical examination by a doctor. Thyroid ultrasound is used to assess the shape, size, and appearance of the nodule, which helps determine if there is a risk of cancer. The nodule is graded using the internationally recognized TIRADS (Thyroid Imaging Reporting and Data System) classification system. Based on the recommendations of this grading system, the patient is monitored and typically scheduled for follow-up in 6-12 months. If cancer is suspected, a biopsy may be performed under ultrasound guidance to make a definitive diagnosis.
