You will be asked to lie on your back. A pillow will be placed under your shoulders. Your neck will be extended. The site of the biopsy will be cleaned. For an FNA, your doctor will insert a tiny hollow needle into the nodule to collect a sample of tissue. For a CNB, your doctor will make a small cut in the skin.

After the procedure, pressure will be applied to the biopsy site. A bandage will be applied.

The transducer will send images to a screen for your doctor to view. These images will be used to locate the nodule and to guide the needle. This helps to make sure your doctor got a sample of the nodule and not the surrounding “normal” tissue.
