What Size Thyroid Nodule Should Be Removed

Why Do Some Benign Nodules Require Surgery

Thyroid RFA what size should you consider treating your nodule.

As mentioned above, thyroid nodules are common and occur in 40% of women and 30% of men during their lifetime. Most nodules are benign, but some of these nodules require thyroid nodule surgery. Thyroid nodules are often diagnosed as benign by needle biopsy during patient evaluation. Although these nodules are benign, almost all of them grow or enlarge over time. Therefore, nodule size is one of the reasons for benign thyroid nodule surgery. Any nodule that is 4 cm or larger should be surgically removed with a thyroid nodule. Thyroid surgery is also highly needed for nodules that have abnormal or suspicious cells on biopsy. This allows for definitive diagnosis and treatment.

What Is A Normal Size For Thyroid Nodules

Thyroid nodules range in sizeyour doctor will decide what to do depending on their size.

  • Tiny nodules, which are less than 1 cm in diameter. These arent usually biopsied.
  • Nodules larger than 1 cm with suspicious features are biopsied. Those that are slightly larger and have fewer suspicious features may not be biopsied until they reach a size of 1.5 to 2 cm.
  • Very large nodules are surgically removed. This is necessary because of an increased risk for thyroid cancer and potential to damage nearby structures in the neck.

Nodules of any size that get bigger should also be biopsied.

A common misconception is that nodules can be shrunken by medications, such as thyroid hormone replacement. This was an approach used by doctors a long time ago, but it was found to be ineffective. In fact, it can cause harm to the heart in the form of irregular and fast heartbeats and weaken bones so it is no longer a recommended treatment. Dr. Arakawa

What Is A Grade 3 Thyroid Nodule

Introduction: The Bethesda System classifies suspicious thyroid nodules or those with a large size after fine-needle aspiration depending on the risk of malignancy through its cytology study. Bethesda category 3 implies atypia of uncertain significance or follicular lesion of undetermined significance.

Thyroid Nodule Removal: Summary

Thyroid nodules are very common. Thyroid nodule removal, involving surgical resection of half or the whole thyroid, is often necessary to diagnose and cure these nodules, particularly when they are cancerous. Large nodules , multiple nodules with or without a thyroid goiter , and ones that are atypical or suspicious require thyroid nodule removal. Even benign nodules may need surgery depending on symptoms, growth, or size.

Expert evaluation and treatment for thyroid nodules are paramount. Our team of thyroid cancer experts is here to help and guide you every step along the way and will be there for you after your thyroid nodule removal. To learn more and become a patient, please see our resources below.

Navigating The Debate On Managing Large Thyroid Nodules

Papillary Cancer Management

1. Background

Thyroid nodules are an increasingly common incidental finding in the general population, with the increased use of imaging technologies. They are especially common in older adults, females, and individuals with iodine deficiency or radiation exposure . Studies estimate a prevalence of up to 6% by palpation, 1968% with ultrasound, and 865% by autopsy . Detecting and treating thyroid malignancy early in these nodules is ideal, but navigating algorithms for the management of thyroid nodules may pose complex clinical decisions for clinicians.

However, increasingly more studies show much lower FNA false-negative rates, 05.2%, in large 4cm nodules . These studies suggest monitoring is more appropriate than surgery . In addition, a meta-analysis from 2018 found that there were not large enough differences in false-negative rates to support routine surgery .

The purpose of this project was to describe the patients at the University of Vermont Medical Center with 4cm thyroid nodules and determine the proportion of patients who had surgery that was potentially not necessary for diagnostic purposes, predictors associated with unnecessary surgery, and the cost of unnecessary thyroid surgeries.

Are Large Thyroid Nodules Cancerous

Most thyroid nodules are benign, but about 2 or 3 in 20 are cancerous. Sometimes these nodules make too much thyroid hormone and cause hyperthyroidism. Nodules that produce too much thyroid hormone are almost always benign. People can develop thyroid nodules at any age, but they occur most commonly in older adults.

Causes Of Thyroid Nodules

Thyroid nodules, masses in the thyroid gland, can be the result of benign cell overgrowth or actual discrete tumors comprised of thyroid cells that can be benign or cancerous. Thyroid nodules can sometimes contain fluid, which usually collects due to bleeding from the fragile blood vessels in thyroid tumors, so called cystic degeneration. This event sometimes causes the sudden onset of pain and swelling in the front of the neck, which typically subsides over several days.

Fortunately, more than 90% of thyroid nodules are not cancers, but malignancy should be considered in every affected person. Often patients with small thyroid nodules, less than 1 cm in diameter, and no risk factors for thyroid cancer can simply be reexamined or imaged by sonography to be sure the nodule is not enlarging. For larger nodules, additional studies are usually indicated, as described below.

What Is The Main Cause Of Thyroid Nodules

The majority of thyroid nodules are caused by an overgrowth of normal thyroid tissue. The cause of this overgrowth is usually unknown, but there is a strong genetic basis. In rare cases, thyroid nodules are associated with: Hashimotos thyroiditis, an autoimmune disease that leads to hypothyroidism.

Is Surgery The Most Definitive Way To Diagnose A Nodule

Thyroid Nodule Biopsy

Most often, a needle biopsy is done before surgery to help diagnose the type of treatment. Patients should know that thyroid biopsy depends only on the people who perform it and the pathologists who evaluate the cells and that it is good and reliable. The results of a needle thyroid biopsy are classified according to the Bethesda system to report thyroid cytopathology for thyroid nodules. The diagnostic categories are as follows:

  • Not diagnostic or satisfactory
  • Atypia of unknown significance or follicular lesion of unknown significance
  • Follicular neoplasm or suspected follicular neoplasm
  • Suspected of malignancy

Most thyroid nodules are found incidentally when a person has a scan for another reason. A thyroid nodule is more likely to be talked about when it causes symptoms, such as: -A feeling of fullness in the throat -Difficulty swallowing -Hoarseness or change in voice -Cough that isnt due to a cold or other respiratory infection

The vast majority of thyroid nodules are benign, meaning they are not cancerous. However, a small percentage of thyroid nodules can be cancerous, and these need to be treated differently.

Thyroid Nodules And Treatment: Get The Facts

For many patients, being told they have athyroid nodule instantly raises red flags. DoI have cancer? Will I need surgery? Should I be worried?

The answer to these questions is usually, butnot always, no. Thyroid nodules are lumps that form within your thyroid, abutterfly shaped gland located at the base of your neck. Nodules can be solidor contain a variable amount of fluid. If they are completely fluid-filled,they are called thyroid cysts.

Thyroid nodules are more common in womencompared to men and more likely to occur as you get older. The exact reason whysome people get thyroid nodules and others dont is not known, but nodules tendto run in families.

Most thyroid nodules are benign and cause no problems if left untreated. However, approximately 5 to 10 percent of thyroid nodules are cancerous but even then, a patient might not need surgery right away because most thyroid cancers grow slowly.

If you have been diagnosed with a thyroid nodule, the first step is to see an endocrinologist a doctor who specializes in conditions of the endocrine glands, such as the thyroid.

Most thyroid nodules are benign and cause no problems if left untreated. However, approximately 5 to 10 percent of thyroid nodules are cancerous but even then, a patient might not need surgery right away because most thyroid cancers grow slowly.

Surgery For Thyroid Nodules & Cancers

Most noncancerous, or benign, thyroid nodules do not need treatment unless they are a cosmetic concern or cause symptoms including problems with swallowing, breathing, or speaking and neck discomfort. In these situations, NYU Langone doctors may recommend surgery or a minimally invasive procedure called radiofrequency ablation.

Doctors may also recommend surgery to manage a thyroid nodule if a biopsy shows its cancerous or if genetic testing shows its likely to be cancerous.

People with toxic nodules or toxic multinodular goiters that are causing the thyroid to produce high levels of thyroxinea condition called hyperthyroidismmay also be recommended for surgery

People who have a lobectomy can often go home the day of surgery, but those who have a total thyroidectomy usually need to stay in the hospital overnight. You may experience minor discomfort for a few days, which can be managed with pain medication.

A thyroidectomy stops or decreases production of thyroxine. Your doctor replaces thyroxine with a synthetic hormone called levothyroxine, taken by mouth daily. This medication helps keep your metabolism functioning properly and prevents hypothyroidism.

If you have thyroid cancer, doctors may prescribe levothyroxine to keep thyroid-stimulating hormone levels on the low side or even fully suppressed to minimize the growth of any remaining thyroid cancer cells.

Some people produce enough thyroxine after a lobectomy and do not need levothyroxine. An NYU Langone endocrinologist assesses your hormone levels after lobectomy to determine whether you need medication.

Thyroid Molecular Markers Allow Patients To Avoid Surgery

We want to help patients find that perfect balance between under-treatment and over-treatment. The people-gram shows how molecular testing can help patients avoid unnecessary surgery.

Left Path: Before the use of molecular markers, everyone with an indeterminate biopsy went to surgery. Of those who went to surgery, cancer was found in only 25% of those cases . 75% of the surgical patients turned out not to have needed surgery at all because their nodules were benign .

Right Path: Today, if you have an indeterminate biopsy, you also undergo molecular testing. 50% of patients were categorized as benign from the molecular test and safely avoided surgery. Of the surgical patients who received a suspicious molecular test result , cancer was found in 50% of those patients .

It is very rare that patients end up having cancer because of a false negative test. Still, it is UCLAs standard of care to have a safety net and follow every patient after molecular testing, regardless of their result. Those patients will get ultrasounds every 12 months to ensure that nodules do not grow or change in appearance.

At What Size Should Thyroid Nodules Be Removed

Asked By : Glenn Martinez

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.

Could The Number Of Nodules Be One Of The Reasons For The Need For Surgery

Thyroid Nodules Explained

Multiple thyroid nodules, especially when part of the thyroid is enlarged , may require surgery. Even if a nodule or 2-3 nodules are benign on a needle biopsy, an enlarged thyroid with multiple nodules often requires thyroid nodule surgery for several reasons. First, monitoring and biopsy of more than 2-3 nodules is very difficult and impractical. Second, multiple thyroid nodules and goiters often eventually cause symptoms. Symptomatic thyroid nodules require thyroid nodule surgery. The most common sign or problem of multi-nodular goiter is the unpleasant aesthetic appearance of a large lump in the neck or symptoms caused by the actual size of the goiter. Symptoms of goiter size may include a lump in the throat, difficulty swallowing, difficulty breathing, and even in severe cases, a change in voice or a very harsh voice. Finally, thyroid nodules or thyroid goiters that have grown under the clavicle and inside the thoracic cavity always require thyroid removal.
