Thyroid Cancer - What To Expect When You've Been Diagnosed
Everything You Want & Need To Know About Thyroid Cancer
I was diagnosed with thyroid cancer in 1999. Little did I know I was to learn more about the thyroid, and thyroid cancer, than I ever cared to! It has been a long road, and I learned much along the way. I hope by sharing my journey with thyroid cancer with you, it will help you with yours.
When I Was First Suspected of Having Thyroid Cancer
Back in the fall of 1998, I went for a regular physical examination. My doctor was feeling around my throat when she asked "Have you ever noticed this lump in your neck?" I replied "You said something about that last year". So she told me that I needed to go see a Ears-Nose-Throat specialist. She said it was probably nothing to worry about, but that I should get it checked out.
It took a couple of months before I got an appointment with the specialist. He was a great doctor, and he examined me thoroughly. He found what he believed was a nodule on my neck, and told me that he thought I might have thyroid cancer. I just looked at him in disbelief! I think perhaps when you hear the word "cancer" that it feels as if your life stops at that point. I suppose it is the shock, especially when you aren't expecting to hear anything like that!
I was scheduled for some x-rays and sonograms, which determined that I had a two nodules in my thyroid gland.
What and Where Is My Thyroid Gland?
Your thyroid is a gland that is located in your neck. It lays against and around your larynx, and is about where your Adam's apple is located (if you are a man). It is shaped somewhat like a butterfly, with the lobes of the thyroid being the butterfly's "wings". The two lobes are connected by the isthmus, which can change in shape and size.
The thyroid gland controls how you feel and how your body functions. It produces hormones that circulate in your blood throughout the rest of your body.
One of the main effects of thyroid hormones is to regulate your body's metabolism. In other words, how your body metabolizes carbohydrate, protein, and fat. This is why some people who have weight problems can attribute the gain or loss to low or high thyroid hormone.
The thyroid hormones also regulate your growth and development; and physical and mental development and function. It also affects your heart rate.
Biopsy of Thyroid Gland
Fine Needle Aspiration
The next step was for me to have a biopsy of the nodule on my thyroid gland. This is called a "Fine Needle Aspiration". I was sent to yet another specialist for this. I laid on a table, and the nurse brought in what appeared to be an extremely huge needle. This was to deaden the area where the biopsy was to take place.
It was a horrible experience! The nurse slowly injected the anesthetic, and I had a really difficult time staying still! The biopsy? It was a piece of cake after that! The doctor simply inserted the needle through the skin into the nodule, and withdrew a bit of it.
It took a week or so to get the results, and they believed that yes, I did have thyroid cancer. I was referred back to the ENT specialist to discuss my options.
What Is Thyroid Cancer?
Basic Facts about the thyroid cancer
Thyroid cancer is the most common endocrine cancer. It is defined as a malignant tumor or growth originating within the thyroid gland. It is also called thyroid carcinoma. It is one of the few cancers that has increased in incidence over recent years. More than 48,000 people were newly diagnosed with thyroid cancer in the United States in 2011, and more than 200,000 people were newly diagnosed worldwide in the same year.
Thyroid cancer occurs across all age groups, but is more common in people age 20 to 55. It is common more often in women in than men.
The cause of thyroid cancer is unknown. However, you will have a higher chance of getting thyroid cancer if you were exposed to large amounts of radiation during childhood, or received radiation treatment for medical problems in the head and neck area at a young age. The cancer may not occur until 20 years or more after the radiation exposure. Most people who have thyroid cancer, however, were never exposed to radiation.
Thyroid cancer is highly treatable if diagnosed early. Prognosis depends on a number of factors, including:
1) Type of thyroid cancer (there are 4 types)
2) Size of the tumor
3) Whether the cancer has spread to other parts of the body
4) Your age at the time of diagnosis
I was 39 years old when diagnosed with papillary / follicular thyroid cancer. This puts me in the right age & sex category, and like most people, I was not exposed to radiation when I was young. I guess I was just (un)lucky!
The "Good Cancer"
Thyroid cancer is called the "good cancer" because many types of thyroid cancer are highly survivable.
Total removal of the thyroid gland
The ENT told me that it would be best if I had a total thyroidectomy. This is where the whole thyroid gland is removed. Some people only have part of it taken out, but there is always a chance of recurrence. Depending on what was found after surgery, I might have to have radiation.
Of course, he had to tell me about the complications of surgery:
1) Raspy voice (He said I might sound like Demi Moore)
2) Possible loss of voice
3) If they cut in the wrong place, I might not be able to swallow and/or breathe
4) Low calcium levels in the blood, if the parathyroid glands are damaged during the procedure.
5) Infections and bleeding
I have to admit, this scared me a lot! Mostly, I was scared of being put to sleep by the surgery and never waking up. After all, I was only 39, and had big plans for my 40th birthday!
So the next thing I did, was get a 2nd opinion. I had another fine needle biopsy, and this time, without the area being deadened. It didn't hurt near as much as the first one did! Results were still the same, and I decided to go with the surgery.
Removal of My Thyroid Gland
The surgery wasn't as bad as I expected. I arrived at the hospital early in the morning, got into my gown, and was knocked out pretty quickly. I don't remember what happened at all! However, when I did awaken, I was in pretty bad pain and was receiving morphine through an IV. When I reached up to my neck, I found the wound covered with steri-strips.
The doctor came in,and told me that they had found papillary cancer with a follicular variant. They removed the entire thyroid, in addition to one of my parathyroid glands. Everything looked good, and I should be out of the hospital the next day.
**As an aside to this story.***
I was released the next day, and had a good afternoon. I woke up in the night coughing, and couldn't breathe. A friend took me to the emergency room, where I was seen by a doctor. He said I looked fine, and sent me home. Two days later I was back in the ER, and learned I had pneumonia! I spent the next 4 days in the hospital recovering from that!
4 Types of Thyroid Cancer
Papillary, Follicular, Medullary, and Anaplastic
1) Papillary thyroid cancer is the most common type of thyroid cancer. It accounts for about 80% of all thyroid cancers. It generally grows very slowly, but can often spread to lymph nodes in the neck. It also can spread elsewhere in the body.
2) Follicular thyroid cancer accounts for about 10-15% of all thyroid cancers. Follicular thyroid cancers usually do not spread to the lymph nodes, but in some cases can spread to other parts of the body, such as the lungs or bones.
3) Medullary thyroid cancer accounts for 5-7% of all thyroid cancers. Medullary thyroid cancer is easier to treat and control if found before it spreads to other parts of the body. Sometimes it spreads before a thyroid nodule is discovered. The treatment for this type of thyroid cancer is surgery. The long-term prognosis is not as positive as it is for papillary or follicular thyroid cancer.
4) Anaplastic thyroid carcinoma is the least common type of thyroid cancer. It accounts for only 1-2% of all thyroid cancers. It is seen more commonly in people over age 60 than in younger people. In many people, it is seen together with other forms of thyroid cancer. This rarest type of thyroid cancer is difficult to control and treat because it is very aggressive and can spread rapidly within the neck and to other parts of the body.
What Are Radioactive Iodine Ablation Treatments?
Also Known As Radioiodine, I-131 or RAI
Some people, like me, receive radioactive iodine treatments after surgery. This is to get rid of any remaining cancer cells or tissue that the surgeon might have missed, or that are located in other parts of the body. This is a painless, but very strange, procedure.
If RAI is part of your treatment, you will probably receive it between 3 and 6 weeks after your surgery. You will swallow the RAI in the form of either one or more capsules (pills) or a liquid. RAI works because the thyroid gland needs iodine and absorbs it from the bloodstream. When you swallow the RAI (the isotope I-131), it goes through your bloodstream to your thyroid tissue. The radiation destroys thyroid cells, both cancerous and normal thyroid cells, with minimal effects on the rest of your body.
The dosage of I-131 used for ablation is measured in millicuries. The dose for remnant ablation may range from 30 millicuries to 100 millicuries. Sometimes the dose is higher (100 to 200 millicuries) for people with more extensive disease. The first time I had RAI treatments, the dosage of I-131 was 100 millicuries. The second time, it was 150.
Radioactive Iodine Ablation Procedure
What Happens During The Procedure
This type of radiation treatment is different than most, because it is internal. It is also one of the strangest things I have ever experienced!
Most people have this done in the hospital, mainly because you are highly radiated. When you enter the hospital, you have to give up your clothes, and wear a hospital gown & slippers. Everything in your hospital room is covered with plastic wrap, including the toilet seat, faucets, telephone, and flooring.
Someone from the Nuclear Medicine department will bring you your dosage. It is usually in a metal box, and only you can touch it. Swallow the dosage, and then be prepared to wait it out. You will probably not feel different, although you will have a slight metallic taste in your mouth.
When the staff brings you a meal, it is on disposable plates. It will probably be a low iodine diet, as iodine can mess up your RAI. After eating, you'll throw everything away yourself. No hospital staff to wait on you! I had 2 bags in my room, with radiation markings on them.
Now, the best way to get out of the hospital is to take a lot of showers. And I mean a lot! Every hour or so, hop in and wash off. Any radioactive iodine that is not sucked up by the cancer or thyroid cells will be lost through perspiration. Your goal is to get it out of your system so you can go home.
Potential Side Effects
1) A burning sensation or tenderness in the neck area
2) Nausea and upset stomach
3) Swelling and tenderness of the salivary glands
4) Taste changes (usually temporary)
5) Dry mouth
6) Reduction in tear production
I always believed on leaving my hospital room that I must glow in the dark from all of the radiation!
Precautions To Take After RAI
After you leave the hospital, there are precautions you have to take in order to not expose others to your radiation:
1) You must stay at least 3 feet away from everyone for approximately 5 days. This includes your pets. And do not kiss anyone!
2) If you are in the car or on public transportation, do not sit next to anyone for more than an hour. If you are in the car, sit in the back, behind the passengers seat.
3) You should sleep in a separate room, or at least 6 feet away from any other person. Use separate bath towels and launder these and all of your other clothing separately for one week.
4) Use separate eating utensils or disposable eating utensils. Wash eating utensils separately for one week. Do not prepare food for others.
5) Rinse the sink and tub thoroughly after using them. Shower every day.
6) Wash your hands with soap and plenty of water every time you use the toilet. Flush the toilet each time you use it, and wash the toilet seat.
7) If you need to travel by plane or other transportation after receiving RAI, carry an information card or letter of explanation from your doctor. This is because radiation detection devices used at airports, bus and train stations, trash collection sites, and some international borders and in some buildings may detect low radiation levels. Carry the card or letter with you for at least 3 months after receiving RAI.
Whole Body Scan
Follow up to RAI Treatment
Between 2 and 10 days after your RAI treatment, you will have a whole body scan, which is also known as an I-131 scan. You will have this scan in the nuclear medicine department of the hospital or community radiology center. It usually takes between 30 minutes and hour.
Fully clothed, you'll lie still on a narrow bed that moves slowly through a scanner. Some of the newer scanners actually do the moving, and the bed lies still. A monitor will be above your head showing your progress. Unfortunately, since you cannot move, it's tough to see what is happening.
Normally, you won't know the results of your scan until your next doctor appointment. However, in some centers, a nuclear medicine doctor will meet with you afterwards for the result.
About 98% of people who have the scan show a small amount of thyroid tissue. This is because it is difficult for the surgeons to remove every tiny bit of your thyroid. If you see "normal uptake in the neck" in your results, this is what they are referring to. The scan will also show uptake in your salivary glands and digestive tract, and will also provide information about whether and where there is any remaining thyroid cancer.
Thyroid Hormone Replacement Therapy
Since your thyroid was removed surgically, you will receive thyroid hormone replacement therapy (levothyroxine) for the rest of your life. You will have to have blood tests periodically to determine your TSH, T3 and T4 levels. This is what your dosage will be based on.
Levothyroxine comes as a tablet to take by mouth. It usually is taken once a day on an empty stomach, about an hour before breakfast.
There are a lot of drugs that you cannot take at the same time as Levothyroxine. Some of these are antacids and iron tablets. Your doctor or pharmacist will tell you how to take all of your medicines.
After you take this medication for awhile, you'll learn what dosage makes you feel "normal", and also when to tell your doctor you need a change. Hair loss, cold intolerance and unexplained weight gain are all signals that your dosage might need to be changed.
Unfortunately, not all doctors will listen when you feel you need a change. If you've had thyroid cancer, your TSH level is different than someone who has thyroid disease. It's best to find a doctor who specializes in thyroid cancer, as he/she will have a better understanding of what you require.
Blood Tests & Scans
Follow up procedures
During the first year after your treatment, your physician will order blood tests several times to make sure you are on the right dosage of levothyroxine. Blood testing also helps monitor for persistent or recurrent cancer. Make certain to ask for your results, and keep track of them in a notebook.
After the first year, your doctor may order blood tests less often. Make sure to ask for one on your own if you are feeling tired, cold, or are gaining weight. This is a good indicator that you need to either raise or lower your dosage.
You will have these blood tests for the rest of your life, so get used to it!
The prognosis for any person with a recurrence is better if it is discovered early. This is why life-long monitoring is important.
Other Tests & Scans
Your doctor will determine what other types of procedures you will need for the rest of your life. These tests & scans include:
1) Physical neck examination, including feeling the thyroid bed area. Typically, this is done every 3 to 6 months for the first 2 years, and at least once a year thereafter.
2) Neck ultrasound.
3) RAI Whole Body Scan (for people with papillary or follicular thyroid cancer, or a variant. ) This is somewhat like the ablation, but you don't have to stay in the hospital. First, you'll quit taking your levothyroxine for about 6 weeks. By the time you start feeling really crummy, you'll go to the Nuclear Medicine department at your hospital, where you'll receive a dosage of radioactive iodine. 3-4 days later, you'll report back to the hospital for the scan. Keep in mind that you will have to stay away from others during this time.
4) CT Scan, particularly of the head and neck and/or the chest.
5) MRI, of the head and neck and/or the chest.
6) PET/CT Scan
7) Chest X-ray - normally for low-risk patients whose initial cancer was treated via a lobectomy.
Make certain you get the results from all tests, and write them in your notebook. You will be surprised how often you refer back to them!
Thyroid Cancer - A Life-Long Journey
It has been 15 years since I was initially diagnosed with thyroid cancer. For the most part, I am doing fine. My last whole body scan was done in 2005. I was supposed to have one the next year, but lost my insurance, and couldn't afford it.
I do have blood tests every 6 months or so, mainly to get my levothyroxine prescription renewed. Almost every time, it has to be adjusted. Sometimes I have to fight with the doctors about it, when I'm not feeling "just right". It's just one of those things you have to live with... and I'm thankful every day that I have that opportunity!
In late 2013, my primary care physician ordered a whole body PET/CT scan, that showed possible cancerous cells in the thyroid bed. A follow-up CAT scan of just the neck area did not detect any abnormalities. However, there was a lesion on one of my tonsils, and I'm now following up on this. When you've had radiation of any type (especially external beam radiation), it's possible for it to cause cancer in other places approximately 20 years later.
As of May 2014, it looks as if the lesion is gone on my tonsils. This is good, because the only way to learn if you have cancer in your tonsils is to have them removed. This is not a good surgery when you are an adult! After 3 visits to have it checked out, I'm now free to go on my way for another year.
As for the possible cancer cells in my thyroid bed, I'm still working on that. The doctor wants a re-check in 6 months. When I get a clear go-ahead, or have more tests or treatments, I'll let you know.
If you, or someone you know, has been diagnosed with thyroid disease, you'll need as much information as you can find! Here are some additional resources to help you on your journey:
- Thyroid Cancer Survivors Organization
This organization has a great deal of information on all types of thyroid cancer, and what to expect before and after treatment. They also have a yearly survivors conference. I attended one year, and learned much more than my doctor - or any book -
- American Thyroid Association
More indepth information and up-to-date clinical information on the types and treatment of thyroid cancer. A good place to start if you are looking for a thyroid cancer specialist!
