Thyroid Cancer Symptoms, Diagnosis,Cost and Treatments

According to the National Cancer Institute, there are over 56,000 new cases of thyroid cancer in the US each year, and the majority of those diagnosed are papillary thyroid cancer—the most common type of thyroid cancer. Females are more likely to have thyroid cancer at a ratio of 3:1. Thyroid cancer can occur in any age group, although it is most common after age 30, and its aggressiveness increases significantly in older patients. Approximately 1.2 percent of all men and women will be diagnosed with thyroid cancer during the course of their lifetime.

This article will highlight some common thyroid cancer signs and symptoms as well as thyroid cancer prognosis and treatments.

Visit our Patients' Guide to Thyroid Cancer for more comprehensive information on types, causes, diagnosis, and treatments for the different types of thyroid cancer.

Thyroid Cancer Symptoms

Thyroid cancer frequently presents without any symptom whatsoever.  When a symptom does present, the most common symptom is a lump in the neck. Less commonly, patients may have symptoms including hoarseness or change in voice.  Symptoms of pain are very uncommon except in inflammatory conditions of the thyroid and the rarer of thyroid cancers called medullary thyroid cancer.

Although as many as 75% of the population will have thyroid nodules, the vast majority are benign. Young people usually don't have thyroid nodules.  However, children and adolescents with thyroid nodules are most commonly benign, but the overall risk of thyroid cancer is markedly higher than in the adult population.  As people age, they are more likely to develop a thyroid nodule. By the time we are 80 years of age, 90% of us will have at least one thyroid nodule.

Fewer than 1% of all thyroid nodules are malignant (cancerous). Thyroid nodules are most commonly identified due to routine physical examination or x-ray studies obtained for other reasons.  The below MRI study was obtained for a patient complaining of neck pain following a motor vehicle accident.  The red arrow points to a right thyroid mass (the right and left sides are reversed in x-rays) which was confirmed to be papillary thyroid cancer by ultrasound-guided needle biopsy.

Types of Thyroid Cancer

There are 4 main types of thyroid cancer, and some are more common than others.

Thyroid cancer type and incidence:

  • Papillary and/or mixed papillary/follicular thyroid cancer: ~ 85%
  • Follicular and/or Hurthle cell thyroid cancer: ~ 10%
  • Medullary thyroid cancer: ~ 3%
  • Anaplastic thyroid cancer: ~ 1%

Thyroid Cancer Prognosis

Most thyroid cancers are very curable. In fact, the most common types of thyroid cancer (papillary and follicular thyroid cancer) are the most curable. In younger patients, less than 50 years of age, both papillary and follicular cancers have a more than 98% cure rate if treated appropriately. Both papillary and follicular thyroid cancers are typically treated with at least complete removal of the lobe of the thyroid gland that harbors cancer.  A thyroid gland that has a thyroid cancer nodule within it and has multiple other nodules in both sides of the thyroid or when cancer has spread to lymph nodes in the neck is a clear indication for complete removal of the thyroid gland.

Only expert thyroid surgeons should perform thyroid surgery for nodules that may be cancers or patients with known thyroid malignancy.  When expert evaluation of patients with thyroid nodules and cancers combined with expert thyroid surgery provides patients with the best outcomes.

The bottom line is that most thyroid cancers are papillary thyroid cancer, and this is one of the most curable cancers of all cancers. More than 98% of patients with papillary thyroid cancer remain alive after five years.  Unfortunately, nearly 11% of patients with papillary thyroid cancer continue to have thyroid cancer following their initial thyroid cancer surgery.  The most important thing for a patient with a new diagnosis of thyroid cancer is to not be in a rush, take a deep breath, and seek evaluation and care by thyroid cancer experts.

This video for newly diagnosed thyroid cancer patients addresses the most common concerns.


Medullary thyroid cancer is significantly less common but has a worse prognosis. Medullary cancers tend to spread to large numbers of lymph nodes very early on and therefore require a much more extensive operation than the more localized thyroid cancers, such as papillary and follicular thyroid cancer. Extensive means more thorough and a wider or broader area. However, in almost all expert thyroid surgery, all major nerves, blood vessels, and muscles are spared!

Medullary thyroid cancer may also be a genetically inherited cancer and special testing and counseling are indicated for patients with medullary thyroid cancer to determine whether there is a family risk associated with this type of cancer.

Medullary thyroid cancer requires complete thyroid removal plus a dissection to remove the lymph nodes of the front and often along the sides of the neck.

The least common type of thyroid cancer is anaplastic thyroid cancer, which has a very poor prognosis. Unless diagnosed early and found during a thyroidectomy, most cases of anaplastic thyroid cancer lead to a rapid and untimely death.  Anaplastic thyroid cancer tends to be found after it has spread, and is one of the most incurable cancers known to mankind.  Note: Chief Justice William Rehnquist had anaplastic thyroid cancer. You can read about anaplastic thyroid cancer for an in-depth discussion.

The only chance for cure, today, in anaplastic thyroid cancer is when the complete removal of the tumor can be obtained and there is no evidence of spread to other sites in the body (distant spread).  This situation is rarely found.  Anaplastic thyroid cancer patients require chemotherapy and radiation therapy unlike other types of thyroid cancer.  New evolving therapies show some promise in these most aggressive cancers.

Thyroid Cancer and Chemotherapy?

c is unique among cancers. In fact, thyroid cells are unique among all cells of the human body. They are the only cells that have the ability to absorb iodine. Iodine is required for thyroid cells to produce thyroid hormone, so they absorb it out of the bloodstream and concentrate it inside the cell.

The most common thyroid cancers are made up of cells that retain this ability to absorb and concentrate iodine. This provides a perfect "targeted" strategy.

Radioactive Iodine is given to the patients with certain types of thyroid cancers called “differentiated thyroid cancers” following complete removal of their thyroid gland.  These differentiated thyroid cancers include the most common thyroid cancers of papillary thyroid cancer and follicular thyroid cancers. If there are any normal thyroid cells or any remaining thyroid cancer cells in the patient's body (and any thyroid cancer cells retaining this ability to absorb iodine), then these cells will absorb and concentrate the radioactive iodine.

Since most other cells of our bodies cannot absorb the toxic iodine, they remain unharmed. The thyroid cancer cells, however, will concentrate the poisonous radioactive iodine within themselves and the radioactivity destroys the cell from within—no sickness, hair loss, nausea, diarrhea, or pain.  Some normal cells such as your saliva glands, tear glands, breast tissue and bone marrow also will absorb some iodine and receive some potential risk of damage.

Less than twenty percent of patients with papillary or follicular thyroid cancer need or may benefit from radioactive iodine therapy.  Indications for radioactive iodine treatment are based on findings at the time of the operation and final review of the microscopic findings of cancer.  Papillary and follicular thyroid cancers which have spread outside of the thyroid gland itself spread to lymph nodes, or grown into blood vessels are reasons to treat with iodine therapy.  Without such findings, radioactive iodine is not indicated.

Patients with medullary thyroid cancer do not need iodine therapy because medullary cancers never absorb the radioactive iodine. Newer targeted therapies have been developed for medullary thyroid cancer and have been shown to be beneficial when medullary thyroid cancers have spread to distant sites.

Small isolated papillary and follicular thyroid cancers are often cured with simple (complete) surgical therapy alone. This varies from patient to patient and from cancer to cancer. This decision will be made between the surgeon, the patient, and the referring endocrinologist. Remember, a single dose of radioactive iodine therapy is extremely safe. If you need it, take it.

Overview of Typical Thyroid Cancer Treatment

  • Thyroid cancer is usually diagnosed by sticking a needle into a thyroid nodule or removal of a worrisome thyroid nodule by a surgeon.
  • The thyroid nodule is looked at under a microscope by a pathologist who will then decide if the nodule is benign (95% to 99% of all nodules that are biopsied are benign) or malignant (less than 1% of all nodules, and about 1% to 5% of nodules that are biopsied).
  • The pathologist decides the type of thyroid cancer: papillary, follicular, mixed papillary-follicular, medullary, or anaplastic.
  • The patient must be comprehensively evaluated with a thorough high-resolution ultrasound.  Not only must the thyroid be completely examined.  But the entire lymph nodes of the neck need to be examined to determine whether there is any spread to lymph nodes.  Any suspicious lymph nodes must be biopsied prior to surgery so that the correct surgical procedure can be done the first time!  You can find out more about the importance of high-resolution ultrasound in the evaluation of your thyroid nodule or cancer your in this video on thyroid nodules.

The entire thyroid cancer must be surgically removed sometimes with just partial removal of the thyroid gland or total removal of the thyroid gland.  With the use of high-resolution ultrasound before your operation and by expert inspection by your surgeon during your operation, the lymph nodes in the neck are examined to see if lymph nodes also need to be removed.

  • In medullary thyroid cancer, lymph nodes are routinely removed.
  • In the case of anaplastic thyroid cancer, your doctor will help you decide about the need and possibility of a tracheostomy.
  • As early as 5-6 weeks after the entire thyroid has been removed, those patients with indications of a potential benefit of radioactive iodine therapy will undergo radioactive iodine treatment. This is very simple and consists of taking a single pill in a dose that has been calculated just for you. You will need to avoid contact with other people for a couple of days so that others are not exposed to the radioactive materials.
  • One week following the radioactive iodine treatment, you will have to start taking a thyroid hormone pill. No one can live without thyroid hormone, and if you don't have a thyroid anymore, you will need to take levothyroxine (usually one pill a day) for the rest of your life. This is a very common medication (examples of brand names include Synthroid, Levoxyl, Tyrosine).
  • Every 6 to 12 months, you will visit your endocrinologist for blood tests to determine if the dose of daily thyroid hormone is correct for you and to make sure that the thyroid tumor did not return. The frequency of these follow-up tests will vary greatly from patient to patient. Endocrinologists are typically quite good at this and will typically be the type of doctor that you follow up with long-term.

How much does thyroid cancer treatment cost in iran?

Thyroid cancer treatment typically costs starts from $2700. for treatment usually you need surgery and radioactive iodine treatment, which is often recommended for thyroid cancer.

10 common Questions about thyroid cancer

1What are the early signs and symptoms of thyroid cancer?
Thyroid cancer can cause any of the following signs or symptoms: A lump in the neck, sometimes growing quickly. Swelling in the neck. Pain in the front of the neck, sometimes going up to the ears. Hoarseness or other voice changes that do not go away. Trouble swallowing. Trouble breathing.
2Is thyroid cancer deadly?
Thyroid Cancer Prognosis Most thyroid cancers are very curable. In fact, the most common types of thyroid cancer (papillary and follicular thyroid cancer) are the most curable. In younger patients, less than 50 years of age, both papillary and follicular cancers have a more than 98% cure rate if treated appropriately.
3What is the survival rate for thyroid cancer?
98% Overall, the 5-year survival rate for people with thyroid cancer is 98%. However, survival rates are based on many factors, including the specific type of thyroid cancer, and stage of disease.
4What happens if thyroid cancer is left untreated?
Treated or untreated, common thyroid cancer unlikely to cause death. ... The study, led by Louise Davies, MD, MS, and Gilbert Welch, MD, MPH, focused on 35,663 patients with papillary thyroid cancer that had not spread to the lymph nodes or any other area at diagnosis.
5How do you detect thyroid cancer?
Blood tests help determine if the thyroid gland is functioning normally. Removing a sample of thyroid tissue. During a fine-needle biopsy, your doctor inserts a long, thin needle through your skin and into the thyroid nodule. Ultrasound imaging is typically used to precisely guide the needle into the nodule.
6What is the main cause of thyroid cancer?
There are four major types of thyroid cancer: papillary, follicular, medullary (MTC), and anaplastic. The cause of thyroid cancer is unknown, but certain risk factors have been identified and include a family history of goiter, exposure to high levels of radiation, and certain hereditary syndromes.
7Does thyroid cancer have stages?
This is called staging. A doctor needs to know the stage of the disease to plan treatment. In stage I papillary and follicular thyroid cancer, the tumor is any size, may be in the thyroid, or may have spread to nearby tissues and lymph nodes. Cancer has not spread to other parts of the body.
8Can thyroid cancer spread quickly?
These cancers do not tend to spread to lymph nodes, but they can spread to other parts of the body, like the lungs or bones. ... Anaplastic cancer is a rare type of thyroid cancer. It often spreads quickly into the neck and to other parts of the body, and is very hard to treat.
9Can you survive stage 4 thyroid cancer?
Stage 4: In this stage, the tumor has spread into neck tissues under the skin, the trachea, esophagus, the larynx, or distant parts of the body such as the lungs or bones. The 10-year outlook significantly declines at this point: Only 21 percent of people diagnosed at this stage are alive after 10 years
10How long can you live after thyroid cancer?
Statistics on the outlook for a certain type and stage of cancer are often given as 5-year survival rates, but many people live longer – often much longer – than 5 years. The 5-year survival rate is the percentage of people who live at least 5 years after being diagnosed with cancer.
