Do they give anesthesia for a thyroid biopsy?

Local anesthesia has been commonly used to control patient pain during US-FNABs of thyroid nodules (3, 4). The advantages of using local anesthesia include the ability to obtain multiple aspirates without patient discomfort and that patient fear of procedures using needles can be controlled.

A positive marker indicates the need for a total thyroidectomy instead of a lobectomy, and negative markers may support a decision to forgo surgery for a follicular lesion of undetermined significance. Further studies are needed to determine the utility of these tests for indeterminate nodules.

What percentage of thyroid biopsies are cancerous?

Overall, about 5–10% of thyroid FNAs will have malignant cytology, 10–25% will be indeterminate or suspicious for cancer, and 60–70% will be benign (5, 6). Patients with nodules that are malignant or suspicious for cancer by FNA usually undergo thyroid surgery.

Do they numb you for a fine needle biopsy?

A very small needle is used to inject the pain medicine (lidocaine) into the tissues (skin) around the thyroid. This medicine numbs the area beneath the skin. The area will stay numb for a little while after the procedure is over.

How do they numb you for a needle biopsy?

An anesthetic may be injected into the skin around the area to numb it. In some cases, you'll receive an IV sedative or other medication to relax you during the procedure. Sometimes general anesthesia is used during a needle biopsy.

Is a fine needle aspiration painful?

An FNA is an outpatient procedure most often done in the doctor's office. Your doctor might use a numbing medicine (called a local anesthetic), but it's not needed in all cases.

At what size do they remove thyroid nodules?

Thyroid nodules are often diagnosed as benign by needle biopsy during a patient evaluation. Although these nodules are benign, almost all of them will enlarge or grow over time. Thus, size is one reason for benign thyroid nodule surgery. Any nodule that is 4 cm or larger should be removed with thyroid nodule surgery.

What symptoms can thyroid nodules cause?

Most thyroid nodules don't cause symptoms. For people who do have symptoms, they may have trouble swallowing or breathing or have a feeling of fullness, pain, or pressure in the throat or neck. Some people might notice a lump in their neck when they look in the mirror, but this is uncommon.
