Why is a thyroid biopsy ordered and why is it performed?

During ultrasound imaging of the thyroid gland, sonographically suspected nodules are also evaluated with Doppler ultrasound. Usually, the doctor performing the ultrasound distinguishes whether the thyroid nodules are benign or malignant.

Not all thyroid nodules are malignant and not all nodules require a biopsy. However, some nodules may be highly suspicious and some may be intermediate nodules. In these cases, the physician performing thyroid ultrasound recommends a biopsy. In order to determine the type of treatment, biopsy is performed from suspicious nodules under ultrasound guidance. The aim is to clearly understand the content of the nodule.

A very thin dental needle used for dental anesthesia is inserted into the nodule under ultrasound guidance, the cell is collected by moving it slightly inside and exited. The extracted content is then spread on a slide, air-dried or transferred in a special liquid to the pathologist. The patient should not speak or swallow during this time.
