a procedure in which a sample of thyroid tissue is withdrawn for laboratory examination. The sample can be withdrawn through a needle or a surgical incision may be made to obtain a piece of thyroid tissue.
Expect that your endocrinologist will need to do some prep work before the biopsy. This prep work can include asking you to lie down on your back while they use an ultrasound to find the growth. The endocrinologist will mark the area on your neck with a washable marker. These markings are used as a guide to help them remember where to place the needles.
There will be the use of local anesthesia, as well as the use of the fine needles to extract the cells. Because of this, there will be a little bit of blood and some dull pain after the procedure. Your endocrinologist will place a bandage over the area where they performed the biopsy.
Thyroid removal is not necessary for a biopsy.
This is done by extracting cells from the thyroid using a very fine needle. It is usually done under local anaesthetic and then the cells are sent to a cytopathologist to be analysed.
If a needle biopsy is done, no special preparation is needed. If a large needle biopsy is being done, the doctor may order some tests to determine the clotting ability of the blood.

how many days takes to get results for thyroid biopsy? Tanks
The test is generally performed when a lump or a nodule is detected in the thyroid. The test may also be ordered if the thyroid gland is enlarged and the cause is not apparent. The biopsy is usually a test for thyroid cancer.
If an open incisional biopsy is being done, a general anesthetic is required and the patient will be asked to refrain from eating or drinking anything 8-12 hours before the test.
Typically an endocrinologist will perform a fine needle biopsy. Meanwhile an ear, nose and throat doctor - also known as an otolaryngologist - performs the surgical removal of the thyroid.
Some does and don'ts before you undergo a thyroid fine needle biopsy and blood test are: do ask questions, don't go alone, do expect discomfort, don't expect quick results, and do take good care of yourself before and after the biopsy.
The "fine needle aspiration" (FNA) can be done in the doctor's office. An anesthetic is not usually given. The patient will be asked to lie on his or her back. A pillow will be placed under the shoulders and the neck will be extended.
The most accurate diagnostic tool for thyroid cancer is a biopsy. In this process a sample of thyroid tissue is withdrawn and examined under a microscope by a pathologist. This usually takes a day or so.
To acquire a sampling of the cells in a thyroid nodule, an endocrinologist or a radiologist will need to perform a fine needle biopsy. The cells extracted will then be evaluated by a pathologist to determine if the growth is benign or malignant, and if surgery is needed. As for a fine needle biopsy will cause thyroid cancer to metastasize, talk to your doctor.Related Article: How to Prepare for a Needle Biopsy
