How Painful Is A Thyroid Biopsy Do They Numb You For A Thyroid Biopsy
Thyroid biopsies can be performed with very little discomfort. We treat the area where the needle goes in using a numbing cream, a numbing spray, and/or a numbing injection. There may be gentle pressure during the biopsy procedure.
Afterwards, an icepack can soothe the area and reduce swelling. Patients can also use over-the-counter acetaminophen to treat pain.
How Long Does It Take To Get The Results Of A Fine
A fine-needle aspiration biopsy of the thyroid gland is an effective method to determine whether or not a thyroid nodule is cancer. The procedure is relatively simple procedure that is usually performed in a doctor’s office and usually takes less than 20 minutes. Complications are rare but include bleeding, bruising, and infection. Results are generally available within 1 week and help determine what further interventions or treatments are needed.
What To Expect During Your Thyroid Biopsy
A biopsy of your thyroid nodule or lymph node will be recommended for solid nodules > 1.5-2cm , abnormal lymph nodes, and occasionally very suspicious appearing nodules that are 1cm in size. Current guidelines do not recommend thyroid biopsy of nodules < 1cm.
Dr. Goldfarb will perform an ultrasound-guided biopsy that same day in the office and a pathologist will look at the slides in real time to provide a preliminary diagnosis before the appointment is over.
This consists of a very small needle being inserted into your nodule or lymph node 2-3 times on ultrasound guidance. The entire process will take 5-10 seconds per biopsy pass. It will feel slightly uncomfortable and a little strange, but is not overtly painful.

Total Thyroidectomy With Central Neck Dissection
A central neck dissection is when the lymph nodes closest to your thyroid in the central part of your neck are removed during your thyroidectomy.
This is done whenever abnormal lymph nodes are identified on ultrasound before surgery. Sometimes, for patients with larger and/or more extensive papillary thyroid cancer and for all medullary thyroid cancer, this lymph node surgery will be done prophylactically.
How The Test Is Performed
This test may be done in the health care provider’s office or in a hospital. Numbing medicine may or may not be used. Because the needle is very thin, you may not need this medicine.
You lie on your back with a pillow under your shoulders with your neck extended. The biopsy site is cleaned. A thin needle is inserted into your thyroid, where it collects a sample of thyroid cells and fluid. The needle is then taken out. If the provider cannot feel the biopsy site, they may use ultrasound or a CT scan to guide where to put the needle. Ultrasound and CT scans are painless procedures that show images inside the body.
Pressure is applied to the biopsy site to stop any bleeding. The site is then covered with a bandage.

How Do I Prepare For A Thyroid Fna
A thyroid FNA is a day procedure for most people. It takes up to half an hour, followed by a short period afterwards when you will be watched until you have recovered and can leave the hospital or radiology practice. You are generally allowed to resume normal, but non-strenuous, activities for the rest of the day.
You can eat and drink normally before and after the procedure. You will not require a general anaesthetic where you would be asleep, although you may be given local anaesthetic to numb the area of the skin where the FNA needle is inserted.
When you make your appointment for the thyroid FNA, you need to let the hospital radiology clinic or department know if you are taking any blood thinning medication, such as warfarin, clopidogrel, dabigatran, prasugrel, dipyridamole or asantin .
Blood thinning medications will need to be stopped for a period of days, or your normal dose reduced, before this procedure is carried out. It is very important that you do not stop any of these medications or change the dose without consulting both your own doctor and the hospital or radiology clinic where you will have the FNA. They will give you specific instructions about when to stop and restart the medication. These drugs are usually prescribed to prevent stroke or heart attack, so it is very important that you do not stop taking them without being instructed to do so by your doctor or the radiology practice, or both. Aspirin is usually not stopped.
Advancing Molecular Testing In Thyroid Patients
As the field continues to evolve, molecular testing is poised to provide even more precise and clinically valuable diagnostic information to guide appropriate treatment for patients with thyroid nodules. In addition to refining physicians ability to resolve indeterminate thyroid nodules, molecular testing will likely increase in use to inform optimal therapy and measure therapy response, among other uses.
As a physician who has been managing patients with thyroid nodules for over 15 years, I believe the opportunity to provide excellent patient care has never been greater than it is now.

How To Prepare For The Test
Tell your provider if you have drug allergies , bleeding problems, or are pregnant. Also, make sure your provider has a current list of all medicines you take, including herbal remedies and over-the-counter drugs.
A few days to a week before your biopsy, you may be asked to temporarily stop taking blood-thinning medicines. The drugs you may need to stop taking include:
Be sure to talk with your provider before stopping any drugs.
Medical History And Physical Exam
If you have any signs or symptoms that suggest you might have thyroid cancer, your health care professional will want to know your complete medical history. You will be asked questions about your possible risk factors, symptoms, and any other health problems or concerns. If someone in your family has had thyroid cancer or tumors called pheochromocytomas, it is important to tell your doctor, as you might be at high risk for this disease.
Your doctor will examine you to get more information about possible signs of thyroid cancer and other health problems. During the exam, the doctor will pay special attention to the size and firmness of your thyroid and any enlarged lymph nodes in your neck.

Fine Needle Aspiration Biopsy Of Thyroid Nodules
Procedure and interpretation of results
WHAT IS A FINE NEEDLE ASPIRATION BIOPSY OF A THYROID NODULE?
A fine needle aspiration biopsy of a thyroid nodule is a simple and safe procedure performed in the doctors office. Typically, the biopsy is performed under ultrasound guidance to ensure accurate placement of the needle within the thyroid nodule. You will be asked to lie down on your back with your head tipped backwards, so that your neck is extended. Sometimes, a pillow is placed under your shoulders to help you get in the best position for the biopsy.
During the procedure you may feel some neck pressure from the ultrasound probe and from the needle. You will be asked to remain as still as possible and avoid coughing, talking and swallowing during the biopsy.
Are There Any After Effects Of A Thyroid Fna
It is common to have some pain, swelling and even a little bruise where the needle was inserted into your neck. Simple pain medication available from the chemist, such as panadol or panadeine, can be taken for this. Pain and swelling should be minimal after 48 hours.
It is important to avoid strenuous activity, particularly activity that involves bending over, straining or working over your head , as all of these activities can increase the chance of internal bleeding into the thyroid gland.
It is uncommon to have any change in your voice, severe pain, general neck swelling, or difficulty breathing or swallowing after a thyroid FNA. If any of these things happens, you should phone the hospital or radiology practice where the procedure was carried out and let them know.
If you are experiencing difficulty breathing after the procedure, you should go immediately to the nearest hospital emergency department.

What To Expect During The Procedure
FNA is done with such thin needles that local anesthesia is usually not necessary and discomfort is minimal. However, if the biopsy area is particularly sensitive, local anesthetic can be injected to numb the area of the neck to be biopsied. Though the procedure is quite easily tolerated without the use of numbing medicine, its readily available should you need it.
During the procedure, your endocrinologist will:
- Have you lie on your back and place a pillow under your shoulders to extend your neck.
- Clean the site of the biopsy with an antiseptic solution.
- Insert a thin, hollow needle into the nodule using ultrasound imaging to ensure the needle remains on target.
- Extract a sample of cells from the nodule into the needle, which is withdrawn after 15-30 seconds.
- Apply pressure to the biopsy site, after collecting an adequate sample.
FNA of a single nodule takes between 10-20 minutes. Each nodule requiring evaluation is normally aspirated twice in this manner.Since the needles are so thin, bleeding is usually very minimal and a Band-Aid is not usually necessary. You may feel soreness at the biopsy site for one to two days.
What Do I Need To Know About Thyroid Fine
Thyroid fine-needle aspiration biopsy is a procedure to remove tissue and fluid from a nodule in your thyroid gland. This test helps your healthcare provider diagnose thyroid cancer or find thyroid nodules that are not cancer. Your healthcare provider uses the results to decide if you need more treatment.

Who Needs A Fna Needle Biopsy Of Their Thyroid Nodule
FNA biopsy should be done on any nodule that the doctor thinks may be cancerous
- FNA needle biopsy of thyroid nodules is generally done on any thyroid nodules that is big enough to be felt. This means that they are larger than about 1 centimeter across.
- FNA biopsy is indicated on any thyroid nodule that causes symptoms. We have an entire page on symptoms caused by thyroid nodules.
- FNA biopsies should be done on any swollen or abnormal lymph nodes in the neck. This may be more accurate in diagnosing thyroid cancer than FNA of the thyroid nodule itself!
- FNA biopsy should be done on thyroid nodules that have a certain characteristic under the ultrasound.
After Your Needle Biopsy
You can get dressed and go about doing your normal activities straight afterwards. Avoid doing anything too strenuous for the rest of the day.
You will have a small dressing where the needle was.
Your doctor or nurse will tell you how to look after this area and the dressing. Ask if you can bath and shower as normal. You might see some bruising at the site. This is normal, it will go after a week or two. Paracetamol can help if youre sore or tender.

What Happens During A Thyroid Fna
An ultrasound machine will be used to locate the nodule or nodules to be sampled and show images or pictures of the nodule or nodules onto a screen.
The ultrasound will be carried out by a technologist or a radiologist , or both.
The FNA procedure will then be explained to you. Instructions about what you can and cannot do after the procedure will be given to you at this time as well. You will be asked to sign a form indicating that you understand what will happen, the small risks involved, and that you agree to have the procedure done. The explanation will generally be provided by the doctor carrying out the procedure. You will have the opportunity to ask any questions at this time.
You will generally be lying on an examination couch for the procedure.
Your neck will be washed with antiseptic.
The procedure is then over. The needle puncture site in your neck will be compressed for a couple of minutes by the doctor who did the FNA or a nurse who assists the doctor. An ice pack may be put on your neck to help reduce swelling and bleeding. You may be taken from the ultrasound room into an observation area for a short time to ensure that you are well enough to go home.

Preparation For Thyroid Biopsy
How Is A Thyroid Biopsy Performed Are You Awake For A Thyroid Biopsy
Thyroid biopsy is a minimally invasive procedure and is often done in the office setting. Patients are awake for the procedure.
A thin needle is carefully inserted into the thyroid nodule. The needles we use are as small, or smaller, than the needles used to draw blood. Most of the time, we use ultrasound to locate the tip of the needle. The thyroid cells that become trapped inside the needle are analyzed under a microscope. At many of our sites, we examine the cells right away to ensure we have enough material for an accurate diagnosis. A single nodule may need several samples taken to have enough cells for examination. At UCLA, we always save an extra sample for molecular testing, if needed.
After the biopsy we place a small band-aid at the needle site.

Do I Need A Biopsy Or Surgery For My Thyroid Nodule
Thyroid nodules are very common. These masses within the thyroid gland are composed of tissue and/or fluid and are estimated to be present in more than 50 percent of those aged 50 and older. Nodules can run in families, are more common in women, and increase in frequency with age.
Patients diagnosed with a thyroid nodule often ask if their nodule needs to be biopsied or surgically removed. Sometimes the answer is yes, but often the answer depends on a number of patient and nodule-related factors. Catherine Sinclair, MD, FRACS, head and neck surgeon at Mount Sinai West, explains why your nodule may, or may not, need special attention.
How do you know if you need a biopsy?
More than 95 percent of thyroid nodules are non-cancerous, although a family history of thyroid cancer in a first-degree relative or whole-body/neck/chest radiation exposure may increase the risk. Nodules have a low cancer risk, so whether to biopsy depends on the size and ultrasound appearance of the mass.
How is risk measured?
What are the symptoms and treatment for thyroid nodules?
In summary, a thyroid nodule may require an operation if there is a high risk of the nodule being cancerous or if the non-cancerous nodule is large and causing symptoms.
