Thyroid excisional biopsy

How the Test is Performed:
The test is done in a hospital operating room under a general anesthesia. A sedative is usually given by injection about 1 hour before the procedure. An intravenous (IV) line is placed in a vein, usually in your arm. Throughout the procedure, you are given a mixture of anesthetic gas and oxygen through a hollow tube that is inserted through your mouth and into the airway that leads to the lungs. A small incision is made in your neck and either the entire thyroid or a part of the thyroid lump is removed. The sample is sent to the laboratory to be examined while you are still on the operating table. If thyroid cancer is present, your thyroid is removed. The incision is then closed with stitches.

The endocrine system is the chemical control center of the body. The pituitary gland is often considered the master control; sending out hormones that regulate the function of the thyroid, adrenal glands, ovaries, and testis. Over- or under-production of hormones from any of these glands is associated with many different types of disease.



This CT scan of the upper chest (thorax) shows a malignant thyroid tumor (cancer). The dark area around the trachea (marked by the white U-shaped tip of the respiratory tube) is an area where normal tissue has been eroded and died (necrosis) as a result of tumor growth.
