When Is Surgery Needed
All thyroid nodules that are found to contain cancer or highly suspicious of containing a cancer should be removed surgically. Most thyroid cancers are curable with treatment. If the nodule appears benign on FNA or is too small to biopsy , it may be closely followed with ultrasound examination every 6 to 12 months.
This table is a broad idea about the possible treatments for the conditions.
Type of thyroid nodule
|Adenomas Follicular and Hurthle cell neoplasms||There is a 20% risk of cancer in these cases.;Surgical removal;of affected lobe of thyroid gland is needed.|
|Cancer Papillary, follicular & medulary cancer||Total thyroidectomy with or without removal of lymph nodes is needed.|
|Multi nodular goiter –;contains multiple nodules or cysts||Does not usually require any treatment unless there is symptom due to;pressure;and for;cosmetic;reason when surgery is needed.|
|Thyroid Cyst; contain blood or fluid||Does not usually require any treatment unless there is symptom due to;pressure, pain;and for;cosmetic;reason when surgery is needed.|
|Hyperfunctioning Nodule; nodule produces excess thyroid hormone causing server symptoms||Needs medical treatment for controlling excess hormone and then surgery to remove the gland.|
|Parathyroid tumor;- causes calium imbalance in the body.||The affected parathyroid gland needs;surgical removal.|
How Important Is The Microscopic Evaluation Of The Thyroid Cancer That Is Removed By The Surgeon
The pathologic microscopic examination of any thyroid surgical specimen is very important and demanding. There are multiple pitfalls encountered in deriving a precise and accurate diagnosis. That diagnosis significantly impacts upon subsequent investigation, treatment and ultimate prognosis. The more experienced the pathologist, the more likely the diagnosis will be accurate and complete.
Papillary Thyroid Cancer Overview
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 throid 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!

About The Lymph Nodes
The lymphatic system helps protect us from infection and disease. It also drains lymph fluid from the tissues of the body, before returning it to the blood.
The lymphatic system is made up of fine tubes called lymphatic vessels. They connect to groups of lymph nodes throughout the body.
Lymph nodes are small and bean-shaped. They filter bacteria and disease from the lymph fluid. When you have an infection, lymph nodes often swell as they fight the infection.
Papillary Thyroid Cancer: Who Gets It
Papillary thyroid cancer can occur in people of all ages from early childhood to advanced ages although it is most common in people between age 30 and 50. Papillary thyroid cancer affects women more commonly than men, and it is most common in young women. Thyroid cancer is now the fifth most common malignancy among women in the United States. Since it can occur at any age, everybody should be aware of any changes in their thyroid gland and make sure their doctor feels the thyroid gland when getting a routine check-up. For more details on who gets papillary thyroid cancer, the increasing incidence, and ages of patients affected, go to our page on the Incidence of Papillary Thyroid Cancer.

How Will Recurrent Thyroid Cancer Be Found
In the past, radioactive iodine whole body scans were the primary tool used to detect recurrent thyroid cancer. However, the primary tools used today include the blood test marker of thyroid cancer and the neck ultrasound. If the serum thyroglobulin is elevated and the disease is not localized with a neck ultrasound, other radiologic studies are often used to identify the site of disease. These studies may include CT, MRI, and/or FDG PET scanning.
Cancer In Nearby Lymph Nodes
Sometimes cancer is found in lymph nodes that are near to where the cancer started. For example, breast cancer cells may travel to lymph nodes in the armpit or above the collar bone .
If a surgeon removes a primary cancer, they often remove some of the nearby lymph nodes. The lymph nodes are examined to see if there are any cancer cells in them.
The risk of the cancer coming back may be higher if the nearby lymph nodes contain cancer cells. Your doctors may suggest you have more;treatment;after surgery to reduce the risk.
Cancer in lymph nodes that are further away is called;secondary cancer. Cancer found in nearby lymph nodes is usually treated differently to cancer in lymph nodes that are further away from the primary cancer.

Testing Lymph Nodes For Cancer
A swollen lymph node can be felt with your fingertips and sometimes, and if large enough, can be seen. However, there are other areas of the body where lymph nodes are more difficult to find and dont present symptoms on the surface. The only way to confirm a cancer diagnosis in the lymph nodes is through a biopsy.;
A biopsy is performed by using a long, thin needle to remove part of the lymph nodes or lymphatic tissue and reviewing it under a microscope to see if there are cancerous cells. The number of cancer cells will determine the course of treatment. There are additional tests to also determine how far cancer has spread and the cancer stage. All of this plays a part in the type, frequency, and outlook of treatment.;
If you are wondering, is cancer of the lymph nodes terminal, understand that cancer spreadto the lymph nodes does not automatically determine which stage its in.3 Typically, if its traveled far from its originating tumor source, it could indicate a later stage, though there are several tests that can be performed to get a clearer picture. These include:
Not all of these tests are necessary to confirm cancer staging, but they each help deliver more information to make an accurate diagnosis. Furthermore, cancer staging is assigned at the time of diagnosis but can be restaged following treatment. This is based on if cancer has stopped its growth or metastasized to other areas of the body.
Symptoms Treatments And Prognosis For Papillary Thyroid Carcinoma
Papillary thyroid cancer is the most common type of thyroid cancer. You may have even heard your doctor talk about metastatic papillary thyroid cancer . This article will focus on papillary thyroid cancer basics, including papillary thyroid cancer symptoms, treatments, and prognosis. You can read a general overview of thyroid cancer in our Introduction to Thyroid Cancer article.
Visit our Patients’ Guide to Thyroid Cancer for complete information on all types of thyroid cancer, including papillary thyroid cancer.
Papillary thyroid carcinoma is the most common thyroid cancer. About 80% of all thyroid cancers cases are papillary thyroid cancer.1;
Most commonly, papillary thyroid cancers are totally asymptomatic. However, the most common symptom is a mass in the neck. Papillary carcinoma typically arises as a solid, irregular or cystic mass that comes from otherwise normal thyroid tissue. This type of cancer has a high cure rate10-year survival rates for all patients with papillary thyroid cancer estimated at over 90%. Cervical metastasis are present in 50% of small papillary carcinomas and in more than 75% of the larger papillary thyroid carcinomas.
But what do doctors look for;in diagnosing papillary thyroid cancer?
Characteristics of Papillary Thyroid Cancer
Considerable controversy exists when discussing the management of well-differentiated thyroid carcinomas both papillary thyroid cancer and even follicular thyroid cancer.

Secondary Cancer In Distant Lymph Nodes
Cancer cells can break away from the primary cancer and travel through the lymphatic system to lymph nodes further away from where the cancer started. These are known as distant lymph nodes. If cancer cells settle in the distant lymph nodes, it is known as;secondary or metastatic cancer.
When the cancer cells in the distant lymph nodes are examined under a microscope, they look like cells from the primary cancer. For example, when a lung cancer has spread to distant lymph nodes, the cancer cells look like lung cancer cells.
The aim of;treatment;in this situation is usually to destroy as many cancer cells as possible. This can help control the cancer.
Hurthle Cell Cancer Patients With Medium Risk Or High Risk Of Their Cancer Recurring May Require Additional Studies Including:
Radioactive Iodine Whole Body Scanning
This is generally performed with elevated blood levels of TSH. Elevated TSH levels can be obtained by withholding thyroid hormone and making the patient hypothyroid or by giving the patient TSH injections called Thyrogen. Both methods of raising TSH levels are equal in delivering radioactive iodine. A low iodine diet is required for at least two weeks before this examination.
CT scanning of the neck and or chest
In hurthle cell cancer patients with extensive angioinvasion , soft tissue extension or spread to neck lymph nodes, above 50 years of age, a baseline CT scan of the chest should routinely be obtained and periodically re-examined approximately once annually. The baseline CT scan can be used in comparison if Thyroglobulin levels are shown to be increasing during the period of follow-up or recurrence is ever discovered.
A PET scan is a special imaging study using a specially designed sugar that lights up on nuclear imaging and when combined with a CT scan is called a PET/CT scan. PET/CT scan is expectantly useful for hurthle cell cancer follow-up when there is:
- an angry appearing hurthle cell cancer microscopically
- distant spread in the body of the follicular thyroid cancer
- neck recurrence of the hurthle cell cancer
- significant elevation of thyroglobulin levels above what would be anticipated for the known disease
- when there is known recurrent cancer but no detectable thyroglobulin.

Thyroid Cancer In Patients Younger Than 45
The prognosis of a patient under the age of 45 with a differentiated thyroid cancer is good. The thyroid cancer staging system takes this information into account, and classifies these cancers simply into two groups based on whether they have spread to distant organs:
Stage 1: The primary tumor can be any size and the cancer may or may not have spread to lymph nodes. Distant sites in the body are not affected.
Stage 2: The primary tumor can be any size and the cancer may or may not have spread to lymph nodes, but cancer cells have spread to distant areas of the body.
If Treatment Does Not Work
Recovery from thyroid cancer is not always possible. If the cancer cannot be cured or controlled, the disease may be called advanced or terminal.
This diagnosis is stressful, and for some people, advanced cancer is difficult to discuss. However, it is important to have open and honest conversations with your health care team to express your feelings, preferences, and concerns. The health care team has special skills, experience, and knowledge to support patients and their families and is there to help. Making sure a person is physically comfortable, free from pain, and emotionally supported is extremely important.
People who have advanced cancer and who are expected to live less than 6 months may want to consider hospice care. Hospice care is designed to provide the best possible quality of life for people who are near the end of life.
You and your family are encouraged to talk with the health care team about hospice care options, which include hospice care at home, a special hospice center, or other health care locations. Nursing care and special Nursing care and special equipment can make staying at home a workable option for many families. Learn more about advanced cancer care planning.

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.
Assigning A Cancer Stage
Cancer stages are typically assigned a Roman numeral and are determined by the TNM testing and other factors.4 The system is used mostly to describe cancers with solid tumors, such as breast, lung, or colon cancer. TNM stands for:;
- Size of tumor and spread into nearby tissue
- Spread of cancer to nearby lymph nodes
- Metastasis, the spread of cancer to other areas of the body
Stage I: The earliest cancer stage is when a tumor has not grown deeply into nearby tissues and has not yet spread to lymph nodes or other areas of the body. In some cases, cancer staging may be described as in situ which means in place and is technically Stage 0. This early stage is the most curable and usually treated by removing the tumor with surgery.
Stage II and III: These progressive stages indicate larger tumors that have grown more deeply into the tissues and may have spread to the lymph nodes, but may not yet have reached other areas of the body.;
Stage IV: This stage is determined to be the most advanced or metastatic cancer, which means it has spread throughout the body, to the lymph nodes, and beyond.

What Do Survival Rates Mean
When you ask your doctor about your prognosis, they may talk to you about something called “5-year survival rates.” There are a few important things to know when you get this information.
Survival rates are based on research done on large groups of people. They can’t predict exactly what will happen to you. Your outlook depends on things like your age, treatment plan, overall health, etc.
Also, the research that these numbers come from was done 5 or more years ago. Treatments have improved since then.
For thyroid cancer, 5-year survival rates are an estimate of the percentage of people with your cancer type and stage who are still alive 5 years or more after diagnosis, compared to the general population. So if your doctor says the survival rate is 96%, it means that people with thyroid cancer are 96% as likely as people without this cancer to be alive 5 years after diagnosis.
There’s one more complication about interpreting survival rates for thyroid cancer. The numbers come from the National Cancer Institute’s Surveillance, Epidemiology, and End Results database, which collects cancer survival statistics. This database does not use the same staging system as your doctor. Instead, it groups thyroid cancers into three stages:
- Localized: The cancer hasn’t spread outside the thyroid.
- Regional: The cancer has spread to nearby tissues.
- Distant: The cancer has spread to other parts of the body, such as the bones.
Papillary thyroid cancer: Regional – 99%, Distant – 78%
Follow Up For Thyroid Cancer
After treatment for thyroid cancer you have regular follow up appointments. Your doctor will ask how you are and check that there are no signs of cancer.; The number of appointments you have will depend upon the type and stage of your thyroid cancer. It will also depend upon your response to your treatment.
Your appointments may be with your specialist in hospital at the beginning, and with your GP later on.
Recurrence Of Thyroid Cancer
Although thyroid cancer recurrence is not common, there are many treatment options available if it happens. If a cancer recurrence is detected in the neck lymph nodes, the best course of action is usually an operation to remove the affected node or additional treatment with RAI ablation. In order to determine the best treatment for recurrent thyroid cancer, it is critical to work with an experienced team of thyroid specialists.
What Are The Types Of Thyroid Cancer
Thyroid cancer is classified based on the type of cells from which the cancer grows. Thyroid cancer types include:
- Papillary: Up to 80% of all thyroid cancers are papillary. This cancer type grows slowly. Although papillary thyroid cancer often spreads to lymph nodes in the neck, the disease responds very well to treatment. Papillary thyroid cancer is highly curable and rarely fatal.
- Follicular: Follicular thyroid cancer accounts for up to 15% of thyroid cancer diagnoses. This cancer is more likely to spread to bones and organs, like the lungs. Metastatic cancer can be more challenging to treat.
- Medullary: About 2% of thyroid cancers are medullary. A quarter of people with medullary thyroid cancer have a family history of the disease. A faulty gene may be to blame.
- Anaplastic: This aggressive thyroid cancer is the hardest type to treat. It can grow quickly and often spreads into surrounding tissue and other parts of the body. This rare cancer type accounts for about 2% of thyroid cancer diagnoses.
