“Antithyroid medication, radioactive iodine, and surgery are all effective treatments and can restore thyroid function to normal. Radioactive iodine and surgery also can “cure” the hyperthyroidism by removing the thyroid.”
American Thyroid Association
Your thyroid cancer treatment options depend on the type and stage of your thyroid cancer, your overall health, and your preferences.
Most cases of thyroid cancer can be cured with treatment.
Most people with thyroid cancer undergo surgery to remove all or most of the thyroid. Operations used to treat thyroid cancer include:
Thyroid surgery carries a risk of bleeding and infection. Damage can also occur to your parathyroid glands during surgery, which can lead to low calcium levels in your body. There’s also a risk of accidental damage to the nerves connected to your vocal cords, which can cause vocal cord paralysis, hoarseness, soft voice or difficulty breathing.
After thyroidectomy, you’ll take the thyroid hormone medication levothyroxine (Levoxyl, Synthroid, others) for life.
This medication has two benefits: It supplies the missing hormone your thyroid would normally produce, and it suppresses the production of thyroid-stimulating hormone (TSH) from your pituitary gland. High TSH levels could conceivably stimulate any remaining cancer cells to grow.
You’ll likely have blood tests to check your thyroid hormone levels every few months until your doctor finds the proper dosage for you. Blood tests may continue annually.
Radioactive iodine treatment uses large doses of a form of iodine that’s radioactive.
Radioactive iodine treatment is often used after thyroidectomy to destroy any remaining healthy thyroid tissue, as well as microscopic areas of thyroid cancer that weren’t removed during surgery. Radioactive iodine treatment may also be used to treat thyroid cancer that recurs after treatment or that spreads to other areas of the body.
Radioactive iodine treatment comes as a capsule or liquid that you swallow. The radioactive iodine is taken up primarily by thyroid cells and thyroid cancer cells, so there’s a low risk of harming other cells in your body.
Side effects may include:
Most of the radioactive iodine leaves your body in your urine in the first few days after treatment. You’ll be given instructions for precautions you need to take during that time to protect other people from the radiation. For instance, you may be asked to temporarily avoid close contact with other people, especially children and pregnant women.
Radiation therapy can also be given externally using a machine that aims high-energy beams, such as X-rays and protons, at precise points on your body (external beam radiation therapy). This treatment is typically administered a few minutes at a time, five days a week, for about five weeks. During treatment, you lie still on a table while a machine moves around you.
External beam radiation therapy may be an option if you can’t undergo surgery and your cancer continues to grow after radioactive iodine treatment. Radiation therapy may also be recommended after surgery if there’s an increased risk that your cancer will recur.
Chemotherapy is a drug treatment that uses chemicals to kill cancer cells. Chemotherapy is typically given as an infusion through a vein. The chemicals travel throughout your body, killing quickly growing cells, including cancer cells.
Chemotherapy is not commonly used in the treatment of thyroid cancer, but it may benefit some people who don’t respond to other therapies. For people with anaplastic thyroid cancer, chemotherapy may be combined with radiation therapy.
Alcohol ablation involves injecting small thyroid cancers with alcohol using imaging such as ultrasound to ensure precise placement of the injection. This treatment is helpful for treating cancer that occurs in areas that aren’t easily accessible during surgery. Your doctor may recommend this treatment if you have recurrent thyroid cancer limited to small areas in your neck.
Targeted drug therapy uses medications that attack specific vulnerabilities in your cancer cells.
Targeted drugs used to treat thyroid cancer include:
These drugs target the signals that tell cancer cells to grow and divide. They’re used in people with advanced thyroid cancer.
Palliative care is specialized medical care that focuses on providing relief from pain and other symptoms of a serious illness. Palliative care specialists work with you, your family and your other doctors to provide an extra layer of support that complements your ongoing care. Palliative care can be used while undergoing other aggressive treatments, such as surgery, chemotherapy or radiation therapy.
When palliative care is used along with all of the other appropriate treatments, people with cancer may feel better and live longer.
Palliative care is provided by a team of doctors, nurses and other specially trained professionals. Palliative care teams aim to improve the quality of life for people with cancer and their families. This form of care is offered alongside curative or other treatments you may be receiving.
“Even though the diagnosis of cancer is terrifying, the prognosis for most patients with papillary and follicular thyroid cancer is usually excellent.”
American Thyroid Association
Thyroid cancer may be diagnosed after a person goes to a doctor because of symptoms, or it might be found during a routine physical exam or other tests. If there is a reason to suspect you might have thyroid cancer, your doctor will use one or more tests to confirm the diagnosis.
This would include:
–Family History and Physical Exam
–Imaging tests may be done for a number of reasons:
People who have or may have thyroid cancer will get one or more of these tests.
Ultrasound uses sound waves to create images of parts of your body. You are not exposed to radiation during this test.
This test can help determine if a thyroid nodule is solid or filled with fluid. (Solid nodules are more likely to be cancerous.) It can also be used to check the number and size of thyroid nodules as well as help determine if any nearby lymph nodes are enlarged because the thyroid cancer has spread.
For thyroid nodules that are too small to feel, this test can be used to guide a biopsy needle into the nodule to get a sample. Even when a nodule is large enough to feel, most doctors prefer to use ultrasound to guide the needle.
Radioiodine scans can be used to help determine if someone with a lump in the neck might have thyroid cancer. They are also often used in people who have already been diagnosed with differentiated (papillary, follicular, or Hürthle cell) thyroid cancer to help show if it has spread. Because medullary thyroid cancer cells do not absorb iodine, radioiodine scans are not used for this cancer.
For this test, a small amount of radioactive iodine (called I-131) is swallowed (usually as a pill) or injected into a vein. Over time, the iodine is absorbed by the thyroid gland (or thyroid cells anywhere in the body). A special camera is used several hours later to see where the radioactivity is.
For a thyroid scan, the camera is placed in front of your neck to measure the amount of radiation in the gland. Abnormal areas of the thyroid that have less radioactivity than the surrounding tissue are called cold nodules, and areas that take up more radiation are called hot nodules. Hot nodules usually are not cancerous, but cold nodules can be benign or cancerous. Because both benign and cancerous nodules can appear cold, this test by itself can’t diagnose thyroid cancer.
After surgery for thyroid cancer, whole-body radioiodine scans are useful to look for possible spread throughout the body. These scans become even more sensitive if the entire thyroid gland has been removed by surgery because more of the radioactive iodine is picked up by any remaining thyroid cancer cells.
Radioiodine scans work best if patients have high blood levels of thyroid-stimulating hormone (TSH, or thyrotropin). For people whose thyroid has been removed, TSH levels can be increased by stopping thyroid hormone pills for a few weeks before the test. This leads to low thyroid hormone levels (hypothyroidism) and causes the pituitary gland to release more TSH, which in turn stimulates any thyroid cancer cells to take up the radioactive iodine. A downside of this is that it can cause the symptoms of hypothyroidism, including tiredness, depression, weight gain, sleepiness, constipation, muscle aches, and reduced concentration. One way to raise TSH levels without withholding thyroid hormone is to give an injectable form of thyrotropin (Thyrogen®) before the scan.
Because any iodine already in the body can affect this test, people are usually told to avoid foods or medicines that contain iodine for a few days before the scan.
Radioactive iodine can also be used to treat differentiated thyroid cancer, but it is given in much higher doses. This type of treatment is described in Radioactive iodine (radioiodine) therapy.
If you have been diagnosed with thyroid cancer (especially follicular thyroid cancer), a plain x-ray of your chest may be done to see if cancer has spread to your lungs.
The CT scan is an x-ray test that makes detailed cross-sectional images of your body. It can help determine the location and size of thyroid cancers and whether they have spread to nearby areas, although ultrasound is usually the test of choice. A CT scan can also be used to look for spread into distant organs such as the lungs.
One problem using CT scans is that the CT contrast dye contains iodine, which interferes with radioiodine scans. For this reason, many doctors prefer MRI scans for differentiated thyroid cancer.
MRI scans use magnets instead of radiation to create detailed cross-sectional images of your body. A MRI can be used to look for cancer in the thyroid, or cancer that has spread to nearby or distant parts of the body. But ultrasound is usually the first choice for looking at the thyroid. MRI can provide very detailed images of soft tissues such as the thyroid gland. MRI scans are also very helpful in looking at the brain and spinal cord.
A PET scan can be very useful if your thyroid cancer is one that doesn’t take up radioactive iodine. In this situation, the PET scan may be able to tell whether the cancer has spread.
The actual diagnosis of thyroid cancer is made with a biopsy, in which cells from the suspicious area are removed and looked at in the lab.
“Many people with thyroid cancer don’t have any signs or symptoms of the disease.”
MAYO CLINIC
The thyroid is a small gland located below the voice box in the front of the neck. It is made up of two lobes and is shaped like a butterfly. As part of your endocrine system, this gland makes hormones that affect your heart rate, temperature, mental function, and metabolism.
If cells in the thyroid gland grow uncontrollably, they form a nodule (tumor). Most (90 percent) of thyroid nodules are benign (noncancerous). But 1 out of 10 are malignant (cancerous).
Approximately 62,500 people are diagnosed with thyroid cancer in the United States each year. The disease usually affects people between the ages of 20 and 55. Women are nearly three times more likely than men to develop thyroid cancer.
The disease can be hard to catch at first because many thyroid tumors don’t cause symptoms.
Many people with thyroid cancer don’t have any signs or symptoms of the disease.
Some notice small, painless lumps or swellings called nodules in the front of the neck.
Other symptoms can include:
A risk factor for thyroid cancer is a condition, behavior, or other part of your life that increases the likelihood of developing the disease.
It’s important to understand what risk factors you have for developing thyroid cancer so that your doctors can decide which treatment approach will be most effective for you.
The different types of thyroid cancer have different risk factors.
Risk factors for papillary thyroid cancer include:
Risk factors for follicular thyroid cancer include:
Risk factors for medullary thyroid cancer (MTC):
Information about your health and family medical history can help in figuring out your risk for thyroid cancer. This information is important for building a treatment plan that makes sense for you.
“Reye’s syndrome is a rare disorder that causes brain and liver damage. Although it can happen at any age, it is most often seen in children. Reye’s syndrome usually occurs in children who have had a recent viral infection, such as chickenpox or the flu.”

“Diagnosing idiopathic pulmonary fibrosis (IPF) is often a long and difficult process. That’s because IPF is a rare disease that some doctors may not recognize easily. Its symptoms—including a persistent cough, shortness of breath, and fatigue—are common and found in many respiratory and other diseases, making it easy to confuse IPF with other conditions.”
Lungs&You (www.lungsandyou.com)
“The word “pulmonary” means lung and the word “fibrosis” means scar tissue— similar to scars that you may have on your skin from an old injury or surgery. So, in its simplest sense, pulmonary fibrosis (PF) means scarring in the lungs. Over time, the scar tissue can destroy the normal lung and make it hard for oxygen to get into your blood. Low oxygen levels (and the stiff scar tissue itself) can cause you to feel short of breath, particularly when walking and exercising. Pulmonary fibrosis isn’t just one disease. It is a family of more than 200 different lung diseases that all look very much alike.”

“Your doctor will evaluate your signs and symptoms, review your medical history, and conduct a neurological examination. Signs and symptoms of a concussion may not appear until hours or days after the injury. A cranial computerized tomography (CT) scan is the standard test to assess the brain right after a head injury. A CT scan uses a series of X-rays to obtain cross-sectional images of your skull and brain.”
