Reasons You Wouldn’t Have A Thyroid

Frequently Searched Questions | Thyroid Cancer

People can lose their thyroid or have a poor-functioning thyroid for several reasons.


The most common reason people lose their thyroid gland is a surgical procedure called a thyroidectomy. This procedure usually occurs to treat thyroid cancer by removing some or all of the thyroid gland. Sometimes, a doctor will also do a thyroidectomy to treat thyroid nodules, goiter, or enlargement if it interferes with your breathing ability or is otherwise concerning.

Congenital malformation

Some people are born with a malformed thyroid gland or without one altogether. Although it is rare in developed countries, some babies are born with congenital hypothyroidism, leading to long-term intellectual and physical disabilities if left untreated.

There are some instances where you still physically have a thyroid gland, but it is under-functioning:

Radioactive iodine

RA is used to treat hyperthyroidism or Graves’ disease. An overactive thyroid increases your metabolism, which can have damaging health consequences. Often, RA overtreats the thyroid gland, leading to an underactive state. In these cases, people go from hyperthyroidism to hypothyroidism.

Hashimoto’s thyroiditis

This autoimmune condition is one of the leading causes of hypothyroidism. In Hashimoto’s thyroiditis, the immune system attacks your thyroid gland, causing chronic inflammation that eventually suppresses your ability to make thyroid hormones.


What Is Thyroid Cancer

Thyroid cancer is a solid tumor cancer that usually shows up as a nodule, or mass, in the thyroid gland, which is located at the front base of your throat. It occurs when rogue cells reproduce too rapidly for the immune system to control. There are several types of thyroid cancer, but two types papillary thyroid cancer and follicular thyroid cancer are by far the most common, accounting for some 95 percent of cases. Between 1% and 2% of people will get thyroid cancer at some point during their lifetime. It affects three times as many women as men and is most common after age 30, though it can occur in any age group. Thyroid cancer is more likely to be aggressive in older adults.

Papillary And Follicular Thyroid Cancer Stage Iv

If you are at stage IV, it means the cancer has spread. Your doctor assigns the letters âA,â âBâ and âCâ to show how far.

  • Stage IVA The cancer has spread beyond your thyroid. It now is under your skin, or it affects your larynx, esophagus or trachea. A smaller tumor in more distant lymph nodes is also considered stage IVA.
  • Stage IVB The tumor has grown toward your spine or into nearby large blood vessels, like the carotid arteries. These carry blood to your brain, face, and neck. It might have also spread to your lymph nodes.
  • Stage IVC The cancer has spread beyond the thyroid, and to distant sites of the body. It may be in your lungs, bones, and lymph nodes.

How Is Thyroid Cancer Managed Or Treated

Treatments for thyroid cancer depend on the tumor size and whether the cancer has spread. Treatments include:

  • Surgery: Surgery is the most common treatment for thyroid cancer. Depending on the tumors size and location, your surgeon may remove part of the thyroid gland or all of the gland . Your surgeon also removes any nearby lymph nodes where cancer cells have spread.
  • Radioiodine therapy: With radioiodine therapy, you swallow a pill or liquid containing a higher dose of radioactive iodine than whats used in a diagnostic radioiodine scan. The radioiodine shrinks and destroys the diseased thyroid gland along with cancer cells. Dont be alarmed this treatment is very safe. Your thyroid gland absorbs almost all of the radioiodine. The rest of your body has minimal radiation exposure.
  • Radiation therapy: Radiation kills cancer cells and stops them from growing. External radiation therapy uses a machine to deliver strong beams of energy directly to the tumor site. Internal radiation therapy involves placing radioactive seeds in or around the tumor.
  • Chemotherapy: Intravenous or oral chemotherapy drugs kill cancer cells and stops cancer growth. Very few patients diagnosed with thyroid cancer will ever need chemotherapy.
  • Hormone therapy: This treatment blocks the release of hormones that can cause cancer to spread or come back.

Thyroid cancer care is a team sport. Dr. Lieb says you can expect to be cared for by many people during your cancer treatment, including your primary care physician, your endocrinologist, and your surgeon. There will also be pathologists and social workers. Depending on the type of thyroid cancer, you may also see a nuclear medicine team, vascular surgeon, voice specialist, and imaging professionals.

Thyroid Hormone Replacement Therapy

Thyroid hormone replacement therapy is often prescribed after thyroid surgery to replace the hormones that are no longer being produced by your thyroid tissue. Depending on how much of your thyroid was taken out, you may have to take the medication most commonly levothyroxine for the rest of your life.

Thyroid hormone replacement can also help prevent the growth or recurrence of thyroid cancer. It does this by lowering your circulating level of the hormone TSH, which is secreted by your brains pituitary gland and tells your thyroid to make more thyroid hormone. High TSH levels can stimulate the growth of thyroid cancer cells. Higher doses of replacement thyroid hormone tell your body to make less TSH, slowing the growth of any thyroid cancer cells and lowering the odds of your cancer coming back.

It can take a few adjustments to find the correct dosage of thyroid hormone replacement. During this time, you may need to see the doctor every 6 to 8 weeks for a blood draw to determine if your levels are optimal.

What Is A 5

A relative survival rate compares people with the same type and stage of thyroid cancer to people in the overall population. For example, if the 5-year relative survival rate for a specific stage of thyroid cancer is 90%, it means that people who have that cancer are, on average, about 90% as likely as people who dont have that cancer to live for at least 5 years after being diagnosed.

The thyroid gland is a butterfly-shaped organ at the base of your neck. Although small, this mighty organ controls several essential functions all over the body, including regulating cellular metabolism and managing growth and development. When the thyroid gland is not working correctly, the whole body can be affected.

Pathological Analysis And Staging

Living With Thyroid Cancer: The New Normal

Surgical specimens were analyzed and classified as papillary thyroid carcinoma or follicular thyroid carcinoma according to World Health Organization standard at the time of initial treatment. The present study used the histological classification given in the original pathology report. Considering that multiple revisions of the WHO standards took place over the course of the study and samples were analyzed by many different pathologists, we only classified patients as having papillary, follicular, or Hürthle cell DTC.

The primary tumor diameter was determined based on macroscopic analysis of the surgical specimen, when possible. This also was true for invasive carcinoma, with the pathologist making a best estimate in widely invasive cases. For multifocal tumors or in patients with both a papillary and a follicular carcinoma, the diameter of the largest tumor focus was taken for the primary tumor diameter. In cases of an unclear classification at the time of initial diagnosis, specimens were sent to the reference pathologist on thyroid histology for Germany.

Histological grading was not determined or reported because this is not recommended by the WHO. For the present study, we only included those tumors that were classified as papillary or follicular thyroid cancers, without including those classified as poorly differentiated or insular thyroid carcinomas.

What Are The Symptoms Of Thyroid Cancer

You or your healthcare provider might feel a lump or growth in your neck called a thyroid nodule. Dont panic if you have a thyroid nodule. Most nodules are benign . Only about three out of 20 thyroid nodules turn out to be cancerous .

Surgery For Papillary Thyroid Cancer

Papillary thyroid cancer is treated with surgery. It is important to understand that the best chance of cure is to have an expert thyroid cancer surgeon from the beginning. A surgeon who performs surgery for papillary thyroid cancer on a daily basis has a higher cure rate than a surgeon who performs thyroid surgery several times per week, or does other types of thyroid surgery . Surgery for thyroid cancer has become very specialized, so it is important for you to be comfortable with your choice of surgeon.

Death From Other Causes

Thirty-eight patients died from causes other than thyroid cancer. Two died from another pre-existing primary tumour and nine from a cardiac cause. The two patients who died from another pre-existing primary tumour suffered from chronic lymphatic leukaemia and acromegaly respectively and belonged to a group of 26 patients with a history of a primary tumour diagnosed before thyroid carcinoma. Ten of these 38 patients had evidence of persistent thyroid cancer at their latest visit.

What Is Differentiated Thyroid Cancer

Most thyroid cancers are differentiated, according to the American Cancer Society, which means that when the cells are looked at under a microscope they appear similar to normal thyroid cells. Papillary, follicular, and Hurthle cell thyroid cancer are all types of differentiated thyroid cancer. When the cancerous cells are not similar in appearance to normal thyroid tissue, the cancer is called poorly differentiated or undifferentiated. Medullary and anaplastic thyroid cancers fall into this category.

What Are The Symptoms Of A Anaplastic Thyroid Cancer

Unlike almost all other thyroid cancers, anaplastic thyroid cancer usually has symptoms. Although it almost never causes hyperthyroidism or hypothyroidism , it usually grows so fast and grows locally invasive into surrounding tissues that either its rapid growth rate or local invasion produces its first symptoms. The most common symptoms of anaplastic thyroid cancer are the rapid growth of a neck mass and changes to voice and and swallowing. However, rarely does it make people feel bad. Most importantly, anaplastic thyroid cancer is most commonly diagnosed by expert cytologists following fine needle aspiration analysis of cells obtained from the thyroid gland itself or neck lymph nodes containing metastatic anaplastic thyroid cancer!

Types Of Thyroid Cancer

There are 4 main types of thyroid cancer. They are:

  • papillary carcinoma this is the most common type, accounting for about 6 out of 10 cases it usually affects people under the age of 40, particularly women
  • follicular carcinoma accounts for around 3 out of 20 cases of thyroid cancer and tends to affect older adults
  • medullary thyroid carcinoma accounts for between 5 and 8 out of every 100 diagnosed cases unlike the other types of thyroid cancer, medullary thyroid carcinoma can run in families
  • anaplastic thyroid carcinoma this is the rarest and most aggressive type of thyroid cancer, accounting for less than 1 in 20 thyroid cancers it usually affects older people over the age of 60

Papillary and follicular carcinomas are sometimes known as differentiated thyroid cancers, and theyre often treated in the same way.

Anaplastic Thyroid Cancer: How Is It Diagnosed

Living With Thyroid Cancer: After Surgery Follow-up Care

Anaplastic thyroid cancer starts as a growth of abnormal cancer cells within the thyroid. As these cells multiply they form a bump or “nodule” within the thyroid that often sticks out of the side or front of the thyroid gland. Unfortunately, since anaplastic thyroid cancers grow at such a rapid pace, rarely are they found early in their formation or incidentally noted on a routine physical examination. Most commonly, anaplastic thyroid cancers are diagnosed by the patient noticing the rapid development of a neck mass or symptoms caused by direct invasion of the anaplastic thyroid cancer causing a change in voice or swallowing. In fact, anaplastic thyroid cancers may grow so quickly, that other family members or observers may comment upon the rapid development of a lump within an individuals neck. However the mass is discovered, your physician feeling this mass or seeing it as a surprise on some other scan will typically order a thyroid ultrasound to look at the thyroid closely and take pictures of the mass or nodule.

Causes Of Thyroid Cancer

Thyroid cancer happens when there’s a change to the DNA inside thyroid cells which causes them to grow uncontrollably and produce a lump.

It’s not usually clear what causes this change, but there are a number of things that can increase your risk.

These include:

  • other thyroid conditions, such as an inflamed thyroid or goitre but not an overactive thyroid or underactive thyroid
  • a family history of thyroid cancer your risk is higher if a close relative has had thyroid cancer
  • radiation exposure in childhood such as radiotherapy
  • a bowel condition called familial adenomatous polyposis
  • acromegaly a rare condition where the body produces too much growth hormone

Are You Contagious During The Incubation Period

You certainly can bewe know that asymptomatic and presymptomatic people may be contagious in the absence of symptoms. In fact, you may be most contagious before you even have symptoms. A 2021 study published by Boston University School of Public Health in JAMA Internal Medicine found that people infected with COVID-19 were most contagious two days before and three days after symptoms appeared. According to Hawkins, most transmissions occur during that time frame, before people realize they are sick. Then, as the viral load decreases over time, spreading the virus to others becomes less likely.

The important takeaway here is that if you were in close contact with someone who tested positive for COVID-19 or has COVID-19 symptoms, it’s best to stay home for a few days until you know for sure you’re not infected. “Don’t disregard a runny nose, sore throat, or headache, because those are symptoms, especially after an exposure,” Hawkins says.

Can I Lower The Risk Of My Cancer Progressing Or Coming Back

If you have thyroid cancer, you probably want to know if there are things you can do that might lower your risk of the cancer growing or coming back, such as exercising, eating a certain type of diet, or taking nutritional supplements. Unfortunately, its not yet clear if there are things you can do that will help.

Adopting healthy behaviors such as not smoking, eating well, getting regular physical activity, and staying at a healthy weight is important. We know that these types of changes can have positive effects on your health that can extend beyond your risk of cancer.

Papillary Thyroid Cancer Overview

Thyroid Cancer Survival Rate: January 2013

Papillary thyroid cancer is the most common of all thyroid cancers . It can also be called papillary thyroid carcinoma since carcinoma implies a certain type of cancer. Since thyroid cancer is relatively common, and papillary thyroid cancer is the most common form of thyroid cancer, it is very likely that you will know somebody that had or has this form of cancer. Papillary thyroid cancer typically starts within the thyroid as growth, or bump on the thyroid that grows out of the otherwise normal thyroid tissue. Papillary thyroid cancer is clearly increasing in its incidence both in the United States and globally–it is one of the few cancers that are becoming more common, but we don’t know why this is happening. Our Introduction to Thyroid Cancer page has a great general overview of all types of thyroid cancer–read it if you haven’t already!

What Causes Canine Thyroid Cancer

Like other types of cancer, the exact cause of thyroid cancer is not clear. However, there are a couple of possibilities:

  • Stimulation of the Thyroid Glands: One possible cause is believed to be stimulation of the thyroid glands over a prolonged period of time.

    This over-stimulation may progressively cause the thyroid gland cells to change. First, a part of the gland may experience abnormal cell overgrowth . This cell overgrowth may eventually form a benign tumor, which may then develop into a malignant cancerous tumor.

  • Use of Fipronil: Another possible cause is the insecticide fipronil .

    In fact, the U.S. Environmental Protection Agency classifies fipronil as a carcinogen as they have found that exposing animals to fipronil in a lab caused benign and malignant thyroid tumors in such animals.

    Also, according to the Journal of Pesticide Reform, fipronil can cause, amongst other things, “drastic alterations in thyroid function” in lab animals.

    Some visitors to this site also commented that their dogs who had been using Frontline® developed thyroid cancer later on.

    Many surgeons prefer the older method of removing the entire thyroid for all thyroid cancers. How much surgery is performed has an important impact on how you are managed afterwards, how much thyroid hormone you need and many other factors. Because there are many choices to make, it is important that you have a surgeon that understands every option and how it will affect your overall cure rate, whether more surgery will be needed in the future, and many other things.
