My friend Lee had a scare a few years ago. She thought she might have thyroid cancer. It all began when she had a CT scan for something else and it showed a nodule or lump on her thyroid.
Then she had a fine needle aspiration biopsy, which came back suspicious for papillary cancer, the most common type of thyroid cancer.
Just because it was suspicious didn’t automatically mean she had cancer, but her odds were 60 to 70 percent. The next step was surgery to find out for sure.
Your thyroid is a butterfly-shaped organ in your neck, just below the voice box and above the collarbone. Its job is to produce hormones that regulate how the body uses and stores energy. Common problems are an overactive (hyper) or underactive (hypo) thyroid. Lumps on the thyroid are also pretty common.
In the United States, about 0.1 percent or 300,000 new nodules are detected every year. Supposedly, by the age of 60 about half of us have one that can either be felt or shows up on an imaging test like Lee had.
What causes thyroid nodules?
According to the Mayo Clinic, several conditions can cause nodules to develop in your thyroid:
- Iodine deficiency Uncommon in the United States where iodine is routinely added to table salt and other foods.
- Overgrowth of normal tissue Sometimes called a thyroid adenoma; usually serious only if large; some can lead to hyperthyroidism.
- Cyst Fluid-filled and usually benign.
- Chronic inflammation (thyroiditis) A disorder called Hashimoto’s disease, which causes an inflamed thyroid and is the most common cause of hypothyroidism, may increase the risk of nodules.
- Multinodular goiter A goiter is simply an enlarged thyroid. If it contains several nodules, it’s called a multinodular goiter.
- Thyroid cancer Uncommon
The odds of a thyroid nodule being cancer are about 5 percent, says Maine Medical Center endocrinologist, Dr. Daniel Oppenheim. As he points out, “That means 95 percent of the time a nodule is benign.”
Thyroid nodules are most common in:
- Elderly people
- Women
- People with an iodine deficiency
- People with a history of radiation exposure
An ultrasound of the thyroid is probably the best way to pick up and evaluate nodules, but it is not recommended as a routine screening exam. I asked Dr. Oppenheim why, if ultrasound was such an important tool, it wasn’t used for routine screening — like getting a mammogram. “The difficulty,” he said, “is thyroid nodules are very common and overwhelmingly benign. If you were to do an ultrasound on everybody, you would no doubt find lots of nodules that have no clinical meaning whatsoever.”
Instead, he says your health care provider should do a thorough exam of your thyroid and neck during your annual physical. An ultrasound should be ordered if a nodule is felt, you have symptoms or have risk factors.
Risk factors for thyroid cancer
- History of radiation exposure to the head and neck
- Family history of thyroid cancer
- Age under 14 or over 70
- Being a man
- A diet low in iodine
Thyroid nodule symptoms
Most thyroid nodules don’t cause any symptoms and are so small you don’t even know you have one. If it’s larger, you may:
- Be able to feel it
- Notice swelling in your neck
- Feel as if something is in your throat
- Have trouble swallowing
- Have trouble breathing
Treatment for thyroid nodules
If a needle biopsy comes back negative for cancer or the nodule is too small to biopsy, the usual course of treatment is to follow it with regular ultrasound exams.
When a nodule is suspicious for cancer, it’s usually removed surgically, along with surrounding thyroid tissue. “And then,” says Dr. Oppenheim, “what is called a frozen section is done in the operating room — the pathologist is able to look under the microscope and get a sense of what the problem might be. Typically, if it’s clearly benign at the point, the surgeon will stop and that will be the end of the surgery. If the nodule is clearly thyroid cancer, the surgeon will remove the rest of the thyroid gland and usually some lymph nodes from the neck as well.”
Sometimes it isn’t possible to determine if a nodule is cancer right there in the operating room. That’s why it’s important to have a conversation with your surgeon ahead of time so you’re both on the same page about how to proceed. Would you want the surgeon to go ahead and take out your entire thyroid even though it might not have cancer or stop the surgery, knowing you might have to go back into the operating room if it turns out you do have cancer?
If the nodule is benign, even if only part of the thyroid is removed, it’s usually necessary to take thyroid medication because the gland won’t be able to produce the right amount of hormones anymore. “Missing half a thyroid or a whole thyroid really doesn’t make much difference in terms of subsequent treatment if the nodule is benign,” Dr. Oppenheim says.”Some people say, ‘Just take it out while you’re in there.’ Others say, ‘No, I really want to keep as much of my parts as I possibly can. I’m willing to take the risk of a second operation.'”
Thank goodness, Lee’s nodule was benign — no cancer. “It was the best news,” she says.
For a variety of reasons, her thyroid was totally removed. She will always be on medication but says she’s grateful she won’t have to worry in the future.
What about cancer and other thyroid issues?
According to the American Cancer Society, “The chance of being diagnosed with thyroid cancer has risen in recent years and is now more than twice what it was in 1990.”
In a future post, I’ll take a look at why the rate of thyroid cancer has risen, as well as how it is detected and treated. I’ll also look at hypo- and hyperthyroidism.
For more information about the thyroid, visit the American Thyroid Association or let me know if you have any questions, and I’ll do my best to find you the answers.
Diane “Great article Diane. We are experiencing this in our family right now. Thanks for your timing!”
I’ll send out lots of positive energy Jaye.
I’m very happy that your friend Lee has a positive outcome. Thyroid cancer isn’t one that I see a lot written about, so this was informative. I am interested as to why the rate of thyroid cancer has risen so dramatically, so I ‘ll be looking for that next post
Me too, Jacquie. We go back a long way! I’ll let you know when I write the next post.
“I had the exact same thing with 2 inconclusive biopsies, they operated to take out my thyroid and did a biopsy on the table and it was benign so I still have my thyroid!”
Thank you Beth. I’m so glad you’re ok and that you could keep your thyroid!
Thank you for sharing Lee’s story!
You are quite welcome Maggie!
Hope your friend Lee is doing well. Must have been pretty scary. Think I’ll head down to the kitchen and make sure there is iodine in the salt I’m using.
When I read your comment Ken, I realized that I should add information about what causes benign nodules to my post. Lack of iodine is certainly one, but not so much in the United States, where too many food products are laced with salt and more salt (iodized)!
My situation was the opposite. I was asymptomatic and went to an ENT for an unrelated ear problem. In the process of completing the exam, he found my thyroid was swollen on the Right side. An Ultrasound and Fine Needle Biopsy followed along with a second opinion. I was scheduled for a partial Thyroidectomy with a pathologist on the OR. They determined the Nodule was Papillary Cancer so the ENT took the entire Thyroid. The Nodule was less than 1 cm and my Thyroglobulin levels have come back undetectable twice now so I don’t need to do the Iodine treatment. Now I am adjusting to the replacement hormone. All this since January 2014 with the surgery being March 21. It’s been a crazy ride.
Bridget, thank you for sharing your story. It’s great news that it was caught so early, but even so, a lot of upheaval for you. I understand what that’s like. I hope next year will be less chaotic for you.
This hits home for me and my family. We have a family history of thyroid disease, I was diagnosed with an enlarged thyroid with nodules wrapping themselves around my windpipe after becoming pregnant with my first child. Had surgery to remove most of my thyroid, as well as a couple lymph nodes. Tests revealed papillary carcinoma in one nodule. It was caught early. I’d like to see you discuss the symptoms of hypothyroidism, hyperthyroidism and to please get the word out that the traditional TSH test is NOT effective in all treatment of thyroid disease nor is treatment with T4 only medication appropriate for every patient. http://www.stopthethyroidmadness.com/ and http://thyroid.about.com/ are excellent resources that I have used for many years to improve my health post-thyroid surgery.
Jen, thank you for the information and yes, I’ll write a separate post about other thyroid conditions, as well as testing. If you don’t mind, I might followup with you by email when I do.
Diane, that’s fine. I just don’t want others to go through the years of mismanagement that I went through. What works for one patient does not necessarily work for another. This is so true in my family and unfortunately it took me almost 10 years to figure that out. Ten years of experiencing almost every hypothyroid symptom there is even though my TSH level was within “normal” range. Contrary to what doctors will tell you this is not an easy disease to manage and treat and patients who are told by their doctors that if you’re going to have any cancer then thyroid cancer is the “good” cancer to have, I would have serious reservations about continuing with them. Two more sources that have gotten me through the rough years – http://thyroidbook.com/ and http://dearthyroid.org/. Thyroid patients need to be their own advocates and research, research, research!
I am going through this right now. Had needle biopsy on 6 nodules…by Dr. Oppenheim. It was painful, but, he was just great doing it…if I can do it anyone can. I’m so glad you are doing this piece. Thyroid trouble is so misunderstood. It can be SO debilitating, yet, you look perfectly normal. I have found that just because you are in normal range…means nothing!!! The thyroid controls SO many things in our body. I hope this is talked about in the next article. Thanks so much for doing this!
Maureen, thank you for your comment. If you’re interested, I’d love to talk with you when I write the followup posts. I hope you’re doing ok.
I hope your friend is feeling well. This is very informative post about thyroid. During my pregnancy my thyroid became low and I started taking medicine. Now I am fine from last 3 years.
It is very sensitive matter and is cause of many more diseases and problems. I am very conscious about thyroid and always take iodized salt.
Anna, thank goodness your thyroid problem was discovered — if not, it could have harmed you and/or your baby. I’m glad you’re fine now and hopefully, you won’t have any more problems.
It’s good to hear your friend is doing okay. This isn’t a cancer that gets much attention, so what a good idea to write such a post.
Thanks Jeri. Not only is it a cancer that doesn’t get a lot of attention, it’s on the rise — a topic for a future post.
I have past cancer history (bilateral mastectomy). I recently had an ultrasound of the thyroid, got a call the next day telling me I need to see a endocrinologist. The referral says bilateral thyronaegaly cyston (R) nodule oh (L). My brother passed away from adrenal gland cancer 3 years ago. My question is am I more likely to have thyroid cancer than someone who doesn’t have a family history of cancer?? I do have an appointment with a endocrinologist next week but kinda want to know what I have to look forward to. Thank you for anything and or any advice and answers.
Sandy, I’m sorry but I don’t have an answer for you. I found some information on the American Cancer Society’s website that might be helpful. Good luck next week. https://www.cancer.org/cancer/thyroid-cancer/causes-risks-prevention/risk-factors.html
Diane, if a fine needle biopsy comes back positive ( I’m waiting for my results ) – do I have options to having my thyroid removed? I’m asking because I am scheduled to have my parathyroid removed next Thursday – so they are checking out my thyroid nodules seeing they will have me in surgery.
But I’m wondering if there are other options and would prefer to keep my thyroid and all organs if possible . . . your quick reply would be appreciated ! and anyone else’s experience as well. Thank you.
Viviane,
I can’t say if you have other options, but I think it’s an important question to ask your doctor. And if you’re not satisfied with the answer, you might consider getting a second opinion. Good luck.
My name is Devon I am 39 years old ..Here is my Story I went for a routine check-up with my primary care physician.. During the physical exam she noticed that I had a lump on the right side of my neck..She thought that it was a enlarged Thyroid so She ordered for a ultrasound to see if her thoughts were correct… No what they found was a 4cm tumor sitting on my right thyroid nodules and two more tumors less than 2cm sitting on my left side Nodules .. I had one FNA ..which came back insufficient in the first Biopsy reading..So I had a second FNA Biopsy which read suspicious Cells … I am now schedule to see a ENT Doctor .. I am very scared as to what else I will be facing…
Devon,
Of course, you’re scared. Hopefully, it will be nothing serious. I’ll be thinking of you and will send lots of positive energy your way. Remember to breathe. That might sound trite, but it works for me when I’m anxious about something.
i have had nodules for several years. first one, then two, four, six,.. now about a dozen. told them to take them out but of course they would not. every year or so i have to go to be poked and go through all that crap to have them looked at. finally, last week they called and said one looked suspicious for cancer. and made me apt with oncologist. I have been reading and listening to youtube stories and info from docs. Its so frustrating. risk risk risk is all i see. of me talking again, to iodine treatments that say that those treatments can shrink them and save you, yet you can get Leukemia from that treatment! then you ask what are the different options, and people like this say ask your doc. But if your doctors only offer same and will not tell you, how the heck are people supposed to know if people who know will not lay it on the table!
Wow, it sounds so frustrating on top of the worrying that you’re already doing. Have you gotten a second opinion?
Thank you for posting these stories. I am going for biopsy tomorrow on thyroid nodules. It helped reading the comments of others who had this done.
I hope everything turns out alright for you Patricia. I’ll be thinking of you.
