signs of thyroid cancer
Preparing for Your Thyroid Biopsy - UF Health Endocrinology in Jacksonville
Most thyroid nodules are asymptomatic, non-palpable, and only detected by ultrasound or other anatomical imaging studies. The following features raise the suspicion of cancer:
- neck swelling
- difficulty breathing
- A constant cough that isn't caused by a cold
An FNAB helps determine whether a nodule is malignant or benign. But about 30 percent of the time, the results are inconclusive or indeterminate and cannot tell you whether cancer is present. In this case, the recommended follow-up is a repeat FNAB, a punctured needle biopsy, or a lobectomy/thyroidectomy to remove part or all of the thyroid gland. After removal, a pathologist examines the thyroid nodule closely to diagnose or rule out thyroid cancer.
For large thyroid nodules, 4 cm or larger, FNAB results are very inaccurate, misclassifying half of all patients with apparently benign lesions. In addition, inconclusive FNA results indicate a high risk of differentiated thyroid carcinoma. Diagnostic lobectomy is strongly considered in patients with a significant thyroid nodule, regardless of FNA results.

What are thyroid nodules?
ANDthyroidIt is located in the lower front part of the neck, below the larynx and above the collarbone.
A thyroid nodule is a lump in or on the thyroid gland. Thyroid nodules are found in about 6% of women and 1 to 2% of men; they are ten times more common in older people, but often go undiagnosed.
Whenever a nodule in thyroid tissue is discovered, the possibility of malignancy must be considered. More than 95 percent of thyroid nodules are benign, but tests are needed to determine whether a nodule is cancerous.
Benign nodules include:
Most thyroid nodules are benign, but some thyroid nodules are thyroid cancer
A small percentage of thyroid nodules are malignant. You cannot tell whether a thyroid nodule is cancerous based on symptoms or lack of symptoms. These thyroid nodules, which are cancerous, tend to grow very slowly. The very rare thyroid nodule, which is an aggressive thyroid cancer, can present with a large thyroid mass, a solid or immovable mass, or even a change in voice quality. Only in those very rare cases, when the thyroid nodule is an aggressive thyroid cancer, is there an urgent need for immediate thyroid cancer evaluation and surgery by the surgeon most experienced in thyroid cancer. Otherwise, thyroid nodules require careful evaluation and advice from a surgeon experienced in thyroid cancer. In other words, the vast majority of thyroid nodules can be treated without urgency. Take your time, make quick decisions Thyroid nodules allow enough time for resolution in almost all cases. So relax if you're here because you just found out you have a thyroid nodule. Read and understand what this means. And remember that in almost all cases you have time to find out! we created aThyroid nodules and cancer guide appTo help you, they can better understand your thyroid nodule, determine your next steps, and assess your risk for thyroid cancer.

But what if it is thyroid cancer?
A cancer diagnosis is always worrisome, but even if a nodule is thyroid cancer, you still have reason to be hopeful.
Thyroid cancer is one of the most treatable types of cancer. Surgery to remove the gland usually corrects the problem, and recurrence or spread of cancer cells is rare. People who have thyroid surgery may need to take thyroid hormone afterwards to keep their body chemistry balanced.
Whether benign or not, a troublesome thyroid nodule can be successfully treated. Choosing an experienced specialist can give you more opportunities to personalize your treatment and get better results.
Can a breast biopsy tell what stage of cancer you are at?
During a biopsy, the doctor removes small pieces of breast tissue from the suspicious area for laboratory testing for cancer cells.The need for a breast biopsy does not necessarily mean you have cancer.. Most biopsy results are not cancer, but a biopsy is the only way to be sure.

What if you have a cancerous thyroid nodule?
thyroid cancer. However, 5 to 10% of thyroid nodules are malignant or cancerous.most do not cause symptoms. Rarely, they can cause neck swelling, pain, difficulty swallowing, difficulty breathing, or changes in the sound of your voice as they grow.
Thyroid Nodules and Treatment: Know the Facts
For many patients, the news that they have a thyroid nodule immediately sets off alarm bells.Do I have cancer? Do I need an operation? Should I be concerned?
The answer to these questions is usually, but not always, no. Thyroid nodules are nodules that form on the thyroid, a butterfly-shaped gland located at the base of the neck. Nodules can be solid or contain a variable amount of fluid. If they are completely filled with fluid, they are called thyroid cysts.
Thyroid nodules are more common in women than men and become more common with age. The exact reason why some people develop thyroid nodules and others do is not unknown, but nodules tend to run in families.
Most thyroid nodules are benign and will not cause any problems if left untreated. However, about 5 to 10 percent of thyroid nodules are cancerous, and even then, a patient may not need immediate surgery because mostthyroid cancergrows slowly.
If you've been diagnosed with a thyroid nodule, the first step is to see an endocrinologist, a doctor who specializes in disorders of the endocrine glands, such as the thyroid.
Most thyroid nodules are benign and will not cause any problems if left untreated. However, about 5 to 10 percent of thyroid nodules are cancerous, and even then, a patient may not need immediate surgery because most thyroid cancers are slow growing.

What are the symptoms of thyroid nodules?
Thyroid changes can be seen or felt, but most thyroid nodules do not cause symptoms. They are often discovered during a routine physical exam or through medical imaging, such asultrasonicÖComputed tomographyInvestigations carried out for other reasons. Sometimes the tissue in a nodule produces too much thyroid hormone, causing hyperthyroidism, which can be detected by a blood test for thyroid-stimulating hormone. However, most thyroid nodules, including cancerous ones, actually do not function, which means that tests such as the TSH test are normal.
It is important to see your doctor if you:
- Swelling or lump in the neck.
- hoarseness or other voice changes.
- Difficulty swallowing or persistent sore throat.
- Difficult breathing.
- Pain in the front of the neck
- a persistent cough
What are the symptoms of a thyroid nodule?
Molecular Markers for Thyroid Cancer - Masha Livhits, MD and Michael Yeh, MD | UCLAMDCat
Most thyroid nodules do not cause symptoms. Thyroid nodules are usually discovered accidentally during a routine physical exam or during imaging tests such as a CT scan or an ultrasound of the neck, which are done for completely different reasons. Occasionally, patients themselves find thyroid nodules when noticing a lump on the neck when looking in the mirror, putting on the collar, or putting on a collar. Sometimes abnormal thyroid function tests can be the reason why a thyroid nodule is found. Thyroid nodules can produce excessive amounts of thyroid hormone, leading to hyperthyroidism. However, most thyroid nodules, including cancerous ones, actually do not function, which means that tests such as the TSH test are normal. Rarely, patients with thyroid nodules complain of neck, jaw, or ear pain. If a lump is large enough to compress the windpipe or esophagus, it can cause difficulty breathing and swallowing or a tickle in the throat. Rarely, hoarseness can be caused when the lump invades the nerve that controls the vocal cords, but this is usually related to thyroid cancer.
The main points to remember are the following:
- Thyroid nodules usually do not cause symptoms.
- Thyroid tests are usually normal, even when cancer is present in a nodule.
- The best way to find a thyroid nodule is to make sure your doctor examines your throat!

Is a 2 cm thyroid nodule big?
Cancer risk increased to 15% for nodules larger than 2 cm. Cancer risk did not change for nodules larger than this 2 cm threshold. However, the proportion of rarer types of thyroid cancer, such as Hurthle cell and follicular cancer, increased with progression. increase in nodules.
How are thyroid nodules diagnosed?
AFine needle biopsy of the thyroidIt is a simple procedure that can be performed in the doctor's office. Some doctors numb the skin over the nodule before the biopsy, but euthanasia is not necessary, and patients can usually return to work or home afterwards without ill effects.
This test provides information that no test other than surgery can provide. A needle biopsy of the thyroid provides enough information to support a treatment decision more than 85% of the time when an ultrasound is used.
The use of fine needle biopsy has dramatically reduced the number of patients undergoing unnecessary surgery for benign nodules. However, about 10 to 20% of biopsy samples are interpreted as inconclusive or insufficient, which means that the pathologist cannot be sure whether the nodule is cancerous or benign.
In these cases, a doctor experienced in thyroid disorders can use other criteria to decide on surgery.
Athyroid scanis an image of the thyroid obtained after injecting or ingesting a small dose of a radioactive isotope that normally accumulates in thyroid cells. The check will indicate whether the node is overloaded. Because cancer is rarely found in hot nodules, a scan that shows a hot nodule eliminates the need for a fine-needle biopsy. If a hot nodule is causing hyperthyroidism, it can be treated with radioactive iodine or surgery.

Genetic testing for thyroid nodules: Veracyte/Asuragen and Thyroseq confirmed
There are three commercially available genetic testing companies for thyroid nodules: Veracyte, Asuragen, and Thyroseq. They are similar, but each has some unique benefits. Typically, your doctor will only send your FNA biopsy sample to one of these three. Here are some details about genetic thyroid testing:
- ANDVeracyte / ConfirmThe test is best for determining whether the FNA cytology is benign. This is referred to as a "cut-out" test. It is very good to see if a thyroid nodule is benign. If this test says the needle biopsy is benign, the chance that it is actually cancer is less than 4%.
- BothAsuragenjThyroseqthey are evidence of "government." This means they look for genetic abnormalities known to be linked to a thyroid cancer diagnosis. Finding these specific genetic alterations makes diagnosing thyroid cancer much more likely and may also play a role in determining the best surgery for your cancer.

Can a benign thyroid tumor turn cancerous?
lump thatstarts out benign and rarely becomes cancerous. However, your endocrinologist will likely take occasional biopsies to rule out the possibility. If the nodule is hot or producing too much thyroid hormone, the endocrinologist will likely use radioactive iodine or surgery to remove the nodule.

Table 3demonstrates the clinical and sonographic features of isolated macrocalcifications in benign and malignant nodules. Age and sex were not significantly associated with malignancy in definitively diagnosed isolated macrocalcifications. The location of isolated macrocalcification, the presence of other nodules, and sonographic features, including focal rupture of calcification at the anterior border and lobulated contour of the anterior border, were not significantly associated with malignancy. In all five patients who underwent computed tomography of the neck, nodules with isolated macrocalcifications correlated with gross calcified nodules on CT images.

What does the biopsy tell us?
A biopsy can show one of FIVE possible results: The biopsy can be non-diagnostic, benign, indeterminate, suspicious or malignant.
- Not Diagnosis:Non-diagnosis is a technically flawed biopsy. This occurs when a biopsy does not remove enough cells that the cytologist cannot detect. It is usually necessary to repeat them.
- Benigno:Most thyroid nodule biopsies are benign. This suggests that the lump is not cancerous. Patients can almost always avoid surgery for a benign diagnosis unless the nodule is large and is pressing on nearby structures or the nodule is growing.
- Undetermined:Indeterminate means that the biopsy removed enough cells, but the cytopathologist was not sure whether it was benign or malignant. Indeterminate results occur in about 30% of thyroid biopsies. This is a gray area and means that the risk of cancer is around 10-30%. These nodules require additional treatment, such as B. a repeat biopsy, molecular marker testing, or surgical removal. In some cases, we recommend molecular profiling for indeterminate biopsies.
- Suspicious or malignant malignancy:Findings that fall into these two categories are a strong indicator that the cancer is present and usually requires surgical removal.
US investigation and image analysis
All ultrasound examinations were performed using a 5-12 MHz linear transducer and a real-time ultrasound system. A senior radiologist with 21 years of experience performing thyroid ultrasound and interventional procedures retrospectively reviewed all ultrasound images of 3061 patients with 1 cm nodules. The evaluator, blinded to cytopathologic biopsy diagnoses and final diagnoses, retrospectively evaluated all 3852 nodules for the presence of isolated macrocalcifications. An isolated macrocalcification was defined as a calcified nodule with complete posterior acoustic shadowing and no identified soft tissue components within the calcified nodule. The reviewer retrospectively evaluated the sonographic features of isolated macrocalcifications, including size, location, presence of other thyroid nodules, and the presence of a focal anomaly or lobulated outline at the anterior border of a calcified nodule.

What to expect during a thyroid biopsy?
What to expect during a thyroid biopsy depends on the thyroid biopsy technique your doctor has chosen for you. Although most patients receive a fine needle aspiration biopsy, your doctor may also order a core needle biopsy or a surgical biopsy.
fine needle aspiration
A fine needle aspiration is a type of thyroid biopsy done while you are awake. Most patients do not require anesthesia during this procedure. During the test, your doctor will use the imaging guide to insert a small needle into your throat and take a sample of thyroid tissue for analysis. Your doctor may take several samples from different areas of the thyroid, nodules, or lymph nodes near the thyroid. The procedure is performed in a clinical setting and takes about 30 minutes. You can resume your daily activities after leaving the clinic.
Core needle biopsy
A core needle biopsy is similar to a fine needle aspiration, but involves using a larger needle. It can be done when fine needle aspiration does not provide enough information to make an accurate diagnosis.
Surgical biopsy of the thyroid is rarely necessary. During a surgical biopsy, your surgeon will make an incision in your neck to remove the lump. In some cases, it may be necessary to remove part of the entire thyroid gland.
What percent of thyroid biopsies are cancerous? ›
Studies report on possibility of thyroid cancer in about 5% of thyroid nodules. Fine needle aspiration biopsy (FNAB) is the best way to find out whether a thyroid nodule is cancerous or benign. Since most of the thyroid nodules are not cancer, it is important to know which nodules should undergo biopsy.How often are thyroid biopsies cancerous? ›
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 30% of thyroid biopsies. This is a gray zone and means that the risk of cancer is about 10-30%.What percentage of thyroid biopsies are benign? ›
The vast majority — more than 95% — of thyroid nodules are benign (noncancerous). If concern arises about the possibility of cancer, the doctor may simply recommend monitoring the nodule over time to see if it grows. Ultrasound can help evaluate a thyroid nodule and determine the need for biopsy.How accurate is needle biopsy in diagnosis of thyroid cancer? ›
Findings In this systematic review and meta-analysis including 16 597 patients from 36 studies, FNB sensitivity was around 86% and specificity was around 71%. The diagnostic accuracy of thyroid FNB did not significantly change over time. Meaning In this study, FNB remained a reliable test for thyroid cancer diagnosis.What is the chance thyroid nodule is 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.What are the chances of a benign thyroid nodule turning cancerous? ›
Once a biopsy is read as benign there should be a <1% risk that the nodule is actually cancerous.How fast do cancerous thyroid nodules grow? ›
Malignant thyroid nodules are more likely to grow at least 2 mm per year and increase in volume compared with benign thyroid nodules, according to findings published in The Journal of Clinical Endocrinology & Metabolism.What is the average size of a cancerous thyroid nodule? ›
When the analysis of nodule size was compared with the type and distribution of thyroid malignancy, a significant relationship was detected. The majority of cancer cases, having a nodular size of 1.0-1.9 cm, were diagnosed as papillary carcinoma, and 61.9% of cancerous nodules ≥4 cm were follicular carcinomas.What are the characteristics of a cancerous thyroid nodule? ›
Ultrasound can detect the presence, site, size, and number of thyroid nodules, and there have been reports of US characteristics of malignancy, such as ill-defined margin, irregular shape, hypoechogenicity, heterogeneity, absence of cystic lesion and/or the halo sign, the presence of calcification, and invasion to ...Can a radiologist tell if a thyroid nodule is cancerous? ›
The only way to definitively determine if a thyroid nodule is cancerous is to examine it under a microscope. The most common method is called fine need aspiration (FNA) biopsy, where a very small needle is inserted into the thyroid nodule and cells are removed for microscopic examination.

The least common type of thyroid cancer, anaplastic thyroid cancer, has a very poor prognosis.How can you tell the difference between a benign and malignant thyroid nodule? ›
It is widely accepted that Sonography and ultrasound guided FNA Cytology are the modalities of choice for comparison of benign and malignant nodules.What is considered early detection of thyroid cancer? ›
Most early thyroid cancers are found when patients see their doctors because of neck lumps or nodules they noticed. If you have symptoms such as a lump or swelling in your neck, you should see your doctor right away. Other thyroid cancers are found by health care professionals during a routine checkup.How often are needle biopsies wrong? ›
Although tests aren't 100% accurate all the time, receiving a wrong answer from a cancer biopsy – called a false positive or a false negative – can be especially distressing. While data are limited, an incorrect biopsy result generally is thought to occur in 1 to 2% of surgical pathology cases.Can a thyroid biopsy be wrong? ›
Fine-needle aspiration biopsy (FNAB) is an efficient and reliable means for the evaluation of thyroid nodules, and it has been shown to have a diagnostic sensitivity of 89% to 98% and a specificity of 92%.Can you tell if a thyroid nodule is cancerous from an ultrasound? ›
Imaging, especially with the use of high resolution ultrasound, helps to differentiate a malignant nodule from a more common benign thyroid nodule and identify a malignant nodule against a background nodular goitre, the incidence of which varies between 1% and 3% .Can thyroid nodules grow and not be cancerous? ›
An overgrowth of normal thyroid tissue is sometimes referred to as a thyroid adenoma. It's unclear why this occurs, but it's not cancerous and isn't considered serious unless it causes bothersome symptoms from its size. Some thyroid adenomas lead to hyperthyroidism. Thyroid cyst.Are cancerous thyroid nodules curable? ›
Your thyroid cancer treatment options depend on the type and stage of your thyroid cancer, your overall health, and your preferences. Most people diagnosed with thyroid cancer have an excellent prognosis, as most thyroid cancers can be cured with treatment.What makes a thyroid nodule highly suspicious? ›
There are certain factors that make a nodule suspicious for thyroid cancer. For example, nodules that do not have smooth borders or have little bright white spots (micro-calcifications) on the ultrasound would make your doctor suspicious that there is a thyroid cancer present.Can you live with benign thyroid nodules? ›
The prognosis for noncancerous (benign) thyroid nodules is great. They often don't need treatment, and only about 1% of benign thyroid nodules cause thyroid disease, which is treatable.

Benign nodules include: Multinodular goiter, also called a nontoxic goiter.
What are suspicious thyroid biopsy results? ›
“Suspicious” thyroid biopsy: this happens usually when the diagnosis is a follicular or hurtle cell caused lesion. Follicular and hurtle cells are normal cells found in the thyroid. Current analysis of thyroid biopsy results cannot differentiate between follicular or hurtle cell cancer from noncancerous adenomas.What is moderately suspicious thyroid nodules? ›
“Moderately suspicious” or TR4 nodules are 4 to 6 points, and TR5 nodules or “highly suspicious” have sums of 7 points or more. For TR4 nodules, the guidelines recommend fine-needle aspiration if the nodule is 1.5cm or larger, and follow-ups if larger than 1cm.What percentage of thyroid biopsies are inconclusive? ›
Occasionally (~20% of cases), a biopsy will return an inconclusive result (the nodule pathology is described as 'indeterminate', 'atypical' or 'suspicious'). In such cases, the need for surgery may be less clear.Which thyroid carcinoma is most common and has best prognosis? ›
