What Does Hypoechoic Thyroid Nodule Mean

But What If Its Thyroid Cancer

What is a Thyroid Nodule and How Can It be Treated?

A cancer diagnosis is always worrisome, but even if a nodule turns out to be thyroid cancer, you still have plenty of reasons to be hopeful.

Thyroid cancer is one of the most treatable kinds of cancer. Surgery to remove the gland typically addresses the problem, and recurrences or spread of the cancer cells are both uncommon. People who undergo thyroid gland surgery may need to take thyroid hormone afterward to keep their body chemistry in balance.

Whether its benign or not, a bothersome thyroid nodule can often be successfully managed. Choosing an experienced specialist can mean more options to help personalize your treatment and achieve better results.

Laboratory Radiographic And Other Tests That Are Likely To Be Useful In Diagnosing The Cause Of This Problem

In patients who are asymptomatic diagnostic work up can be started in the outpatient setting after the patient has been discharged. For symptomatic individuals, or in specific patients who desire initiation of the work up in the hospital, the following approach can be used .

Initial laboratory testing for patients with thyroid nodules should include TSH, thyroid peroxidase antibodies, and a free thyroxine or FT4 to assess thyroid function. In patients with a history of MEN2, a serum calcitonin level should be measured. All patients with a palpable thyroid nodule, evidence of a goiter, or incidental finding on computed tomography or magnetic resonance imaging should also undergo ultrasound. Ultrasound can help identify the number of nodules, their size and location, and any evidence of worrisome sonographic signs.

If there are symptoms, evidence of thyroid dysfunction, worrisome ultrasound characteristics, or questions as to how frequently to follow up, patients should be referred to an endocrinologist.

What Does A Hypoechoic Nodule On My Thyroid Mean

Hypoechoic means below or beneath and echoetic means to emit sounds. A hypoechoic nodule is one that emits noxious substances from its surface. These are called hypoxic nodules. They are found in the bodys tissues such as blood vessels, nerves, organs and other soft tissue. When these nodules get big enough they cause damage to vital organs like the heart and brain.

A hypoechoic nodule on your thyroid gland may mean that it is leaking toxins into your bloodstream. If you have a large number of them then you could develop symptoms similar to those associated with cancer. The main source of these toxins is food. But if there are too many of them, then they can leak out through your skin and enter your blood stream.

The most common type of hypoechoic nodule is called a thyrotropin releasing hormone receptor positive hyperplasia . T4 PR refers to the fact that the thyroid produces this hormone. TRH stands for triiodothyronine receptor.

When a person consumes food, the stomach breaks it down into tiny little bits. These bits are called molecules. Your body cannot use the nutrients in these molecules directly. Instead, they must undergo a process which involves wrapping them inside a protein coating.

This process is called bioavailability.

If too much builds up in your blood then you may experience symptoms such as those listed below.

The main types of nodules that have been found on the thyroid are described below:

Most Thyroid Nodules Are Benign But Some Thyroid Nodules Are Thyroid Cancer

A small percentage of thyroid nodules are malignant . You can not tell if a thyroid nodule is malignant due to symptoms or lack of symptoms. Those thyroid nodules that are cancer, tend to be very slow growing. The very rare thyroid nodule that is an aggressive thyroid cancer may present with a large thyroid mass, firm or non-mobile mass or even change in vocal quality. Only in these very rare circumstances, when the thyroid nodule is an aggressive thyroid cancer, is there an urgent need for prompt evaluation and thyroid cancer surgery by the most highly experienced thyroid cancer surgeon. Otherwise, thoughtful evaluation and consultation by an expert thyroid cancer surgeon is required for thyroid nodules. In other words, the vast majority of thyroid nodules can be worked up without a sense of urgency. Dont make rash, quick decisionsthyroid nodules in almost all cases provide plenty of time to get figured out. So chill if you are here because you just found out you have a thyroid nodule. Read and understand what this means. And realize that in almost all cases, you have time to figure this out! We have created a Thyroid Nodule and Cancer Guide app to help, you can to better understand your thyroid nodule, determine what you next steps are, and examine your risk of thyroid cancer.

Shrinking Nodules A Success Story

What Does Hypoechoic Thyroid Nodule Mean? Must Check!

Id like to share the success story of a client who was able to reverse her nodules with nutrition, supplements and treating Blastocystis hominis. Her thyroid antibodies are also now in the remission range . This 60 year old woman with asthma, Hashimotos and past exposure to Chernobyl had consecutive ultrasounds on an annual basis to monitor her thyroid nodule. As of 2018, this person still does not have any nodules on her thyroid ultrasound. She did, however, have a flare in asthma and thyroid antibodies in 2017 after having dairy. As a side note, I think the significant dairy reactivity may be due to the Chernobyl exposure and the radioactive toxins concentrated in the milk from cows in Eastern Europe. My theory is that this exposure made people highly sensitized to dairy proteins.

Here are the results from her first test:

11/5/10: First ultrasound

FINDINGS: There is a 6 x 3 x 4 mm hypoechoic solid nodule in the right lobe with multiple small but discrete hyperechoic foci likely due to calcifications. There is a 2 x 4 x 2 mm partly calcified solid nodule in the left lobe that demonstrates shadowing.IMPRESSION: There are bilateral calcified thyroid nodules. The nodules measure under 1 cm in diameter. The nodules are nonspecific in appearance and results should be correlated with clinical and laboratory data. Follow up ultrasound needed in 12 months due to the calcifications.

Us Characteristics Of Thyroid Nodules: Malignant Versus Benign

There is considerable overlap between the appearance of benign and malignant nodules and no single imaging feature can be considered pathognomonic. However, the simultaneous presence of 2 or more suspicious sonographic findings increases the risk of thyroid malignancy. The following discussion comments on the relative value of the various US features of thyroid nodules in suspecting thyroid malignancy.

What Are The Signs And Symptoms Related To Thyroid Nodules

Most thyroid nodules do not cause any symptoms. Some thyroid nodules show up as a painless lump in the neck that you can feel or see. Thyroid nodules usually move up and down with swallowing.

When thyroid nodules become large they may cause symptoms by pressing on the airway or esophagus. These are also called compressive symptoms. Compressive symptoms include:

  • discomfort with swallowing

At the UCLA Endocrine Center in Los Angeles, multiple layers of evaluation are designed to help you avoid invasive tests and surgery whenever possible. Consultation, ultrasound, and FNA can all be performed in a single visit.

Initial evaluation of a newly discovered thyroid nodule begins with:

  • Assessment by an endocrinologist or endocrine surgeon
  • Thyroid function tests
  • Neck ultrasound performed by your doctor

An ultrasound is a highly accurate tool to visualize your nodule. There is no associated radiation with ultrasounds and it is non-invasive. Ultrasounds are cost-effective as most patients really don’t need any other imaging because the ultrasounds are the best way to look at the thyroid, all present nodules, and the lymph nodes in the neck.

Our cytopathologists evaluate over 1000 samples per year, so we are confident in the accuracy of our biopsies. When biopsy does not give a clear answer, we automatically use molecular profiling to refine the diagnosis.

Preoperative Diagnosis Of Thyroid Carcinoma

Two diagnostic procedures play a major role in the preoperative diagnosis of thyroid cancerthe ultrasound examination of the neck, revealing one or more thyroid nodules and the fine needle aspiration biopsy .With the discovery of a thyroid nodule, a complete history and physical examination focusing on the thyroid gland and cervical lymph nodes should be performed. Family history of thyroid carcinoma, prior head or neck irradiation, a growing or fixed nodule with neck lymphadenopathy, male gender as well as some age groups (< 18 and > 70 years of age are clinical factors that are associated with a higher risk of thyroid carcinoma .

The next diagnostic step is the clarification of thyroid function by obtaining a serum TSH. If the serum TSH is subnormal, besides serum levels of free T4 and T3, a radionuclide thyroid scan should be performed to document whether the nodule is hyperfunctioning , isofunctioning or nonfunctioning . Autonomously functioning thyroid nodules do not need further cytologic evaluation because the incidence of malignancy is exceedingly low . On the contrary, a higher serum TSH level, even within the upper part of the reference range, is associated with an increased risk of malignancy . Experimental studies have shown that thyroid cell proliferation is TSH dependent and that highly differentiated thyroid carcinomas retain this response to TSH. Suppressive thyroxine treatment for differentiated thyroid cancer is also based on this TSH dependence .

Are Thyroid Nodules Serious

Thyroid Nodule Suspicious For Cancer – What Should I Do?

Most often the answer is no. You usually canât feel thyroid nodules. Even though they happen from an overgrowth of cells, most thyroid nodules arenât cancer.

About 1 in 10 thyroid nodules turn out to be cancer. Benign thyroid nodules are common. Lots of people get them as they get older. If a thyroid nodule isnât cancerous, it may not need any treatment. Doctors might just watch to make sure it doesnât keep growing or begin to cause other problems.

  • Is my thyroid nodule cancer? If it isnt now, does this mean that I am more prone to developing thyroid cancer?
  • Will my children be more likely to get thyroid nodules?
  • What is the best treatment for my thyroid nodules?

How Big Is Too Big

When it comes to thyroid nodules, the size matters quite a bit.

Studies have shown time and time again that larger thyroid nodules tend to turn into thyroid cancer at a higher rate compared to smaller thyroid nodules.

The magic number in terms of size is 1 cm or 10mm.

But size isnt the only thing that matters.

For instance:

It has been shown that even small thyroid nodules can be cancerous if they have certain and specific findings on thyroid ultrasound.

The number of nodules and their size are not predictive of malignancy, as a nodule smaller than 1 cm is as likely as a larger nodule to harbor neoplastic cells in the presence of suspicious US features.

Thyroid Nodules by Popoveniuc and Jonklaas

For this reason, you never want to judge the risk of thyroid cancer based on the size of your nodule alone.

You will notice that while the size is certainly a risk factor, you should also look at other risk factors including whether or not the nodule is causing symptoms, your age, and what the nodule looks like on ultrasound.

As a patient, though, you can use the size of your nodule as a quick and dirty way to assess whether or not you should be worried.

Well the description of being a complex cyst or a solid mass sounds like it may be suspicious for possible cancer. However, this is a very small mass and there is a likelihood that it is not a cancer. Without actually being able to see the images myself, I really cant make mch more of an educated guess than that.

What Causes Thyroid Nodules

Hypoechoic thyroid nodule: What does it mean and risk of ...

Nodules can be caused by a simple overgrowth of normal thyroid tissue, fluid-filled cysts, inflammation or a tumor . Most nodules were surgically removed until the 1980s. In retrospect, this approach led to many unnecessary operations, since fewer than 10 percent of the removed nodules proved to be cancerous. Most removed nodules could have simply been observed or treated medically.

Chronic thyroiditis is an inflammation of the thyroid gland that develops slowly. It frequently leads to a decreased function of the thyroid . Thyroiditis occurs when the body’s immune system destroys the cells in the thyroid gland. Chronic thyroiditis is most common in women and people with a family history of thyroid disease.

What Is A Solid Thyroid Nodule

Thyroid nodules are growths of abnormal tissue that develop on the thyroid gland. These lumps may be solid or cystic and fluid-filled. A solid thyroid nodule is more likely than a cystic nodule to be malignant. More than 90% of all solid nodules, however, are benign.

The thyroid is a butterfly-shaped endocrine gland that regulates a variety of hormone interactions, including the pace at which the body burns energy, manufactures proteins, and maintains heart function. It is comprised of a right lobe and a left lobe, and is located at the base of the throat below the thyroid cartilage also known as the Adam’s apple. When a cystic or solid thyroid nodule occurs, it is often located at the edge of the thyroid. In this case, the nodule may be experienced by the patient as a lump in the throat. Depending on the size of the patient and the lump, the nodule may be visible in the front of the neck.

One cause of a solid thyroid nodule is thyroid cancer, which is diagnosed in less than 10% of all patients presenting with this type of lump. Another cause is iodine deficiency. Iodine is an essential trace element important to proper physical and mental functions. When too little iodine is consumed, thyroid problems, including nodules, may occur. Hashimoto’s disease, a condition characterized by chronic inflammation of the thyroid, may also result in a nodule.

Determining If A Nodule Is Cancerous

A biopsy is the best way to determine whether a thyroid nodule is cancerous.

A doctor may offer a local anesthetic during this is a minimally invasive procedure, but that might not even be necessary. Theres no special preparation for a biopsy, and most people have no recovery time. The peace-of-mind that a biopsy offers can be worth the nerves over the procedure.

In 80% of cases, a fine needle aspiration biopsy will show that a thyroid nodule is not cancerous. In 5% of cases, the biopsy will show cancer.

Your doctor will be able to determine which of the four types of thyroid cancer you have by looking at the cell samples from the biopsy under a microscope.

In the remaining 15% or so of cases, a biopsy cannot provide a definitive answer about whether or not a thyroid nodule is cancerous. If that happens to you, your doctor will discuss the best course of action, which may involve surgery.

Although its frustrating to not get a clear answer from a biopsy, your healthcare providers will be able to continue working to find out whats behind your hypoechoic thyroid nodule.

Whats The Treatment For A Thyroid Nodule

Even a benign growth on your thyroid gland can cause symptoms. If a thyroid nodule is causing voice or swallowing problems, your doctor may recommend treating it with surgery to remove all or part of the thyroid gland.

If the doctor recommends removal of your thyroid , you may not even have to worry about a scar on your neck. Some patients are good candidates for a scarless thyroid procedure, where the surgeon reaches the thyroid through an incision made on the inside of your lower lip.

A newer alternative that the doctor can use to treat benign nodules in an office setting is called radiofrequency ablation . Radiofrequency ablation uses a probe to access the benign nodule under ultrasound guidance, and then treats it with electrical current and heat that shrinks the nodule. Its simple: Most people treated with RFA are back to their normal activities the next day with no problems.

Size Should Not Inform Management Strategy But Symptoms Warrant Action

Thyroid Nodules – When to Worry? (Signs your nodule could be something more)

For multiple nodules, the recommendation is to follow the guidelines for ultrasound evaluation. Importantly, size is a poor predictor for large nodules, particularly those that extend beyond the screen. If all nodules are similar on sonography, biopsy the largest one however, its more important to identify the highest risk nodule to biopsy rather than the largest one. Another caveat: rule out a substernal goiter , which should be referred for surgery.4

Nontoxic goiter with symptoms such as globus sensation , respiratory symptoms dyspnea on exertion, or dysphasia or those with positional stridor, Pembertons sign, superior vena cava syndrome, or result in voice changes should be referred to surgery,4 Dr. Lee said.

Treatment for simple, nontoxic goiter will depend on the presence of any symptoms, if any, size, location, any compression of trachea but when with concerns, management should be to monitor for growth and development of hyperthyroidism.7

Treatment of goiter with levothyroxine is no longer recommended as results have been mixed and there is significant risk of TSH suppression with adverse effects on bone, particularly in postmenopausal women, and increased risk for cardiovascular disease.7 Of note, diffuse goiters appeared to respond more favorably to treatment than discrete nodules.

Radioactive iodine may be considered to manage lesser symptoms and for those who are not candidates for surgery.8 Recent radiograph studies support the use of iodinated contrast dye.
