How Is Goiter Diagnosed
Several tests can be used to diagnose and evaluate goiter, including the following:
- Physical exam: Your doctor may be able to tell if the thyroid gland has grown by feeling the neck area for nodules and signs of tenderness.
- Hormone test: This blood test measures thyroid hormone levels, which tell if the thyroid is working properly.
- Antibody test: This blood test looks for certain antibodies that are produced in some forms of goiter. An antibody is a protein made by white blood cells. Antibodies help defend against invaders that cause disease or infection in the body.
- Ultrasound of the thyroid: Ultrasound is a procedure that sends high-frequency sound waves through body tissues. The echoes are recorded and transformed into video or photos. Ultrasound of the thyroid reveals the glands size and finds nodules.
- Thyroid scan: This imaging test provides information on the size and function of the gland. In this test, a small amount of radioactive material is injected into a vein to produce an image of the thyroid on a computer screen. This test is not ordered very often, since it is only useful in certain circumstances.
- CT scan or MRI of the thyroid: If the goiter is very large or spreads into the chest, a CT scan or MRI is used to measure the size and spread of the goiter.
How Is A Thyroid Biopsy Performed
A thyroid biopsy, also called a fine needle aspiration , uses a small needle to take a little sample of the cells in the thyroid nodule. The possible outcomes from a biopsy are:
Non-diagnostic: Non-diagnostic is a technically failed biopsy. There were not enough cells taken during the biopsy so the cytologist was not able to determine anything. These usually need to be repeated.
Benign: Most thyroid nodule biopsies come back benign, meaning your doctor is highly re-assured that it’s not cancerous. Patients can almost always avoid surgery unless the nodule is large and pushing on adjacent structures like the airway.
Indeterminate: Indeterminate means there was enough cells taken during the biopsy, but the cytopathologist was not sure if it is benign or malignant. Indeterminate results occur in about 20% of thyroid biopsies. This is a gray zone and means that the risk of cancer is about 10-30%. These nodules require additional work-up such as a repeat biopsy, molecular marker test, or surgical removal.
Suspicious for Malignancy or Malignant: Results categorized in these two categories are a strong indicator that there is cancer present and usually require surgical removal.
Patients usually wait one week for the cytopathologist to examine the cellular characteristic of the biopsy sample. If your doctor is reassured that it’s benign based on the biopsy result, further work-up is stopped and serial ultrasound surveillance is recommended usually once a year.
How Are Thyroid Nodules Diagnosed
Because thyroid nodules dont always have symptoms, you may not notice the condition until your doctor notices it during a physical exam. Nodules can be detected by symptoms expressed by the patient or by your doctor feeling for lumps on your neck. If a thyroid nodule is diagnosed, your doctor will likely recommend that you see an ear, nose and throat specialist, such as New York ENT, to properly diagnose the condition. Your New York ENT doctor may conduct one of the following tests, depending on the individual:
- Thyroid ultrasound provides images of the nodule
- Blood tests checks the levels of thyroid hormones
- Thyroid scan measures the temperature of the nodule
- Fine needle aspiration evaluates the nodule to rule out cancer

What Causes Hashimotos Thyroiditis
Hashimotos thyroiditis is an autoimmune disease where the immune system malfunctions. We do not know exactly why it occurs, but we think it is multifactorial. Excessive iodine may trigger thyroid disease. There is likely a hormonal component because women are affected much more commonly than men. Lastly, there is likely a genetic component because Hashimotos thyroiditis runs in families who have thyroid disease or autoimmune diseases. Some anecdotal evidence suggests that dietary gluten may contribute to Hashimotos thyroiditis and dietary changes may improve some symptoms.
Regardless of the cause, we know that the immune system is finding our thyroid gland abnormal and mounts an antibody attack against the gland. Instead of the immune system protecting the body, the immune system makes antibodies that attack the thyroid gland. A large number of lymphocytes or white blood cells, that are part of the immune system, build up in the thyroid and produce antibodies. These antibodies are anti-thyroid antibodies that are more specifically called thyroid peroxidase antibodies and the anti-thyroglobulin antibodies.
How Are Goiters Treated
Depending on the test results, a goiter might not need to be treated. If it does, treating the thyroid disease causing the goiter usually will decrease or control the enlargement.
Surgery might be needed if the thyroid keeps getting bigger even with treatment and causes discomfort or a very large lump in the neck.

Prevention Of The Nodules
Thyroid nodules prevention methods cant give 100% insurance the tumors wont appear. But it can reduce the risks. What can one do to prevent the nodules? First of all, watch sufficient amount of vitamins, especially iodine. Check the daily amount necessary and consult your doctor whether you should take the supplements.
Among other methods to prevent thyroid nodules and reduce the risks, one can avoid sun exposure and get physiotherapy to the neck.
Thyroid nodules prevention should also include regular US once a year. Especially patients with the small knots and tumors of any kind in the past.
What Are Prognosis For Thyroid Nodules
The prognosis of thyroid nodules is determined by the nodule histological form. When the formation is benign the nodules and cysts are mostly fully recovered. But one should know thyroid cysts can reoccur again. And each case can be different in its difficulty and prognosis. Thats why regular examination is required after the tumor appeared once.
What for thyroid cancer, its not a common thing in the patients with the nodules. Besides, even when it comes to malignancy , the rate of successfully treated cases is high enough. There are 70-80% of the fully treated tumors. But once the cancer appears, we should be aware and monitor it carefully for metastasis.

What Causes Graves Disease
The bodys immune system reacts to the thyroid gland and produces special proteins that attack the thyroid gland. This is called an autoimmune reaction. These antibodies then stimulate the thyroid gland causing increased production and release of thyroid hormones. The exact reason for why the autoimmune reaction is initiated is not fully understood but, in some people, it can be triggered by infection, stress or smoking. Most patients however have a family history of thyroid problems thus suggesting that there is a link.
Lumps Caused By Thyroid Cancer
As mentioned above, thyroid cancer commonly causes a lump to develop in the neck. These lumps typically form near the base of the neck, above the breastbone , and its common for them to be painless and to quickly grow in size. While the thyroid gland usually isnt palpable, when a nodule forms, the lump can often be felt through the skin on the neck, and in some cases is even visible. Oftentimes, the lump will feel noticeably firmer than the tissue surrounding it.
Its a smart ideaespecially if you have risk factors for thyroid cancerto familiarize yourself with how your neck normally feels, and then continue checking your neck on a regular basis for any signs of an abnormality. To check for a thyroid lump, you should:
- Sit or stand up straight
- Ensure that your neck muscles are relaxed
- Tip your head backward and swallow
- Lightly palpate the area surrounding your thyroid gland while doing so to see whether you can feel any lumps or signs of asymmetry
Its important to remember that the presence of a lump in the neck doesnt necessarily indicate thyroid cancer. In fact, the strong majority of thyroid nodules are benign, with less than 5% being cancerous. Nonetheless, a lump near the thyroid gland should never be overlooked. Upon discovering a lump in the neck, its important to promptly consult with a trained medical professional who can diagnose the cause and confirm whether the lump is cancerous.

Vocal Cord Nodules: Causes Symptoms And Treatment Options
Feeling a scratch in your throat? Sounding a little hoarse lately? While a mildly sore throat seems minor, the cause could be more severe than you think.
Vocal cord nodules are small growths on your vocal cords. Your vocal cords are located inside of your voice box, also known as your larynx.
In addition to changing the way your voice sounds, nodules could also cause a number of speech issues.
Vocal nodules most commonly develop in women and children. Nodules are also one of the most common causes of hoarseness for children.
If youre worried that sore throat indicates youve developed vocal cord nodules, dont stress. Instead, it helps to stay informed. Heres everything you need to know about vocal cord nodules.
What Causes Thyroid Cancer
In most cases, the cause of thyroid cancer is unknown. However, certain things can increase your chances of developing the condition.
Risk factors for thyroid cancer include:
- having a benign thyroid condition
- having a family history of thyroid cancer
- having a bowel condition known as familial adenomatous polyposis
- acromegaly a rare condition where the body produces too much growth hormone
- having a previous benign breast condition
- weight and height

Thyroid Nodule Symptom # : Uncomfortable Pressure Sensation On The Breathing Tube
- What to do about it?
A thyroid nodule that causes problems with breathing should almost always be removed with surgery. This is a routine operation because this symptom is pretty common. There is an uncommon thyroid cancer that can present with these pressure on the trachea symptoms, but the vast majority of people with this symptom have a large, benign goiter that needs removed. An ultrasound scan should be done in all patients who have problems breathing related to the thyroid gland.
How Doctors Treat Thyroid Pain
Conventional treatment for a painful thyroid will depend on the cause of the pain.
Typically, thyroid pain is treated with anti-inflammatory NSAIDs like ibuprofen, or corticosteroids like prednisone. If youre found to have hypothyroidism, you may be prescribed T4 thyroid replacement therapy with levothyroxine.
If youre diagnosed with hyperthyroidism, beta blockers may be prescribed to reduce symptoms. Anti-thyroid procedures, such as radioactive iodine treatment or even removal of your thyroid gland, may be recommended.
Radioactive iodine treatment permanently damages your thyroid gland to prevent it from producing excess thyroid hormones. Thyroid removal is a permanent solution. Both approaches leave you hypothyroid for life. A much better approach is to treat the underlying cause of autoimmunity to try to preserve your thyroid gland and its function.
Functional medicine treatment for a thyroid condition attempts to address the root causes of your thyroid symptoms. This may include diet and lifestyle changes, as well as treatment to improve your gut health. Often, drastic measures like thyroid removal can be avoided with this approach.

Thyroid Nodule Symptom # : A Sense That You Need To Swallow Something
- What to do about it?
Like all thyroid nodules that cause symptoms, these patients need a thyroid ultrasound to look at the size, location, and characteristics of the thyroid, how many nodules are present, and where they are located. Often thyroid glands that are big won’t have any ultrasound characteristics that are worrisome for cancer, so most of theses do not need a FNA thyroid needle biopsy. Thus big thyroids comprised of lots of nodules often don’t need a biopsy, which is in direct contrast to nodules that are single, or those that can be seen or felt . However, if a thyroid is big enough that it is causing the patient to be aware of it, and it is causing symptoms of something stuck in the throat, then surgery is probably necessary. Remember, thyroid surgery isn’t just for nodules that we think may be thyroid cancer, surgery is often necessary for benign, non-cancerous thyroid glands which are large and causing the patient symptoms. This situation is quite common. It is also important to know that large thyroid goiters, and nodules that are on the back side of the thyroid are often required to have a CAT scan, since these bigger thyroid glands are not seen as well with ultrasound. This is why you need a good endocrinologist who know which scan to order and which scans are not necessary. Remember, a large thyroid is called a goiter and we have an entire page on thyroid goiters.
When To See A Healthcare Provider
If you feel a new swelling or lump in your neck, or if an imaging test incidentally reveals a thyroid growth, it’s important to schedule an appointment with your healthcare provider right away.
During your appointment, your healthcare provider will:
- Perform a physical examination, including a neck examination
- Order an ultrasound of your thyroid
- Check blood tests that may include a thyroid-stimulating hormone , free thyroxine , and thyroid antibodies
Depending on the results of these tests, your primary care or family healthcare provider may refer you to a healthcare provider who specializes in thyroid care . An endocrinologist may take another look at the thyroid nodule with ultrasound in his or her office and perform a fine-needle aspiration biopsy to see whether cancer cells are present.

The diagnosis of thyroid cancer has been on the rise both in the United States and worldwide, due in large part to the sophistication of high-resolution imaging tests. In other words, these thyroid nodules that would never have been found years ago are now being identified.
While the majority of these small nodules end up not being cancer, determining which ones are is keyâthis is because most thyroid cancers are curable, especially those that are small and have not spread.

How To Perform A Simple Examination To Check For Thyroid Nodules
The thyroid gland makes hormones that travel through your bloodstream to every tissue in your body. These specialized hormones help you stay warm and process energy, while also keeping your organs, brain, heart, and muscles working properly.
If you have a thyroid nodule, you have an abnormal growth in this gland. Fortunately, 90% of these growths are benign, or noncancerous. Some can cause issues, however, and that leftover 10% can even develop into thyroid cancer.
As an experienced endocrinologist in Chelsea, New York, Dr. Ana Maria Kausel can help identify the signs of thyroid nodules. She takes a customized approach to your treatment.
What To Expect During A Doctors Visit
If you experience these symptoms for over two weeks, consider visiting an ear, nose, and throat doctor. An ENT doctor is also known as an otolaryngologist. However, you might also consider seeing an allergist if you believe allergies are the root of your problems.
During your visit, the ENT doctor will:
- Ask if youve been screaming, singing, or straining your voice lately
- Examine your neck, back of your throat, and head
- Examine your vocal cords
The ENT doctor might also ask you to talk at different pitches.
This will make it easier for them to study your vocal folds at work.
During the examination, the ENT will likely use a lighted scope. Theyll use a long tube, called an endoscope, and a flashing light, called a stroboscope, to study your nodules.
The nodules will look like rough patches against your throat.
In some cases, the doctor will record your vocal folds. They might also require a small tissue sample to make sure the growth isnt cancerous.

What Are The Risk Factors For Thyroid Nodules
Risk factors for developing thyroid nodules include:
- Family history. Having parents or siblings who have had thyroid nodules or thyroid or other endocrine cancers increases your chance of developing nodules.
- Age: The chance of developing nodules increases as you get older.
- Gender: Women are more likely than men to develop thyroid nodules.
- Radiation exposure: A history of radiation exposure to the head and neck increases your risk of developing nodules.
Risk factors for developing cancerous thyroid nodules include:
- Family history of thyroid cancer
- A nodule that is hard or is stuck to a nearby structure
- Male gender
Finding Your Thyroid Gland
Your thyroid is at the lower end of the front of your neck, right above your collarbone and below your larynx. The larynx or voice box is a hollow structure connected to your windpipe.
To find your thyroid, slide your fingers midway down the front of your neck, starting from your chin. The first hard spot you touch is thyroid cartilage, which leads to your Adams apple this area is often more prominent in men than women.
The next hard area in your neck is more cartilage, or the cricoid ring encircling your windpipe. Now, two finger-widths lower is your thyroid isthmus, which connects each side of your butterfly-shaped thyroid gland.
You can develop thyroid nodules for several reasons, including having:
- An enlarged thyroid gland
- Increased sweating
You might also feel a lump at the base of your throat when you have a thyroid nodule. These abnormalities usually feel round, and they may move when you swallow. They can also move at the touch of your fingertips.
