What Are Thyroid Nodules?
Thyroid nodules are small lumps that form in the thyroid gland. The thyroid sits at the front of your neck. Most nodules are not cancerous. However, some can cause health problems. For example, they may affect how your thyroid works. Sometimes, they may grow or feel uncomfortable.

What Is Ultrasonography (USG)?
Ultrasonography, or USG, is a safe imaging test. It uses sound waves to create pictures of the inside of your body. Doctors often call it an ultrasound. USG does not use radiation.

These waves bounce back and create images on a screen. The whole process takes about 15 to 30 minutes. There is no pain, and you can go home right after.
What to Expect During the Procedure
