A thyroid biopsy is a procedure to obtain a small sample of thyroid tissue for analysis in a laboratory. This analysis can help diagnose various thyroid disorders, such as cancer. It can also be used to characterize thyroid disease and help in treatment planning.

In most cases, no special preparation is needed. If you are on medication, your doctor might advise you regarding which medication you can take on the day of your biopsy. No fasting is required, and no anesthesia is needed, so you can drive yourself to and from your appointment.

You will be given a local anesthetic to numb the area where the needle enters your body. The needle is inserted into the suspicious area of the thyroid gland in your neck, precisely guided by the doctor using ultrasound imaging. The sample is then obtained by the needle and the needle is removed. A band-aid is then placed where the needle was inserted. It only takes a few minutes and you can resume most normal activities immediately.

Biopsy results are typically available within one week of the procedure. Your doctor will discuss the findings with you, along with any recommendations.
