Overview of Thyroid Cysts

Thyroid cysts are nodules that form within the thyroid. There are two types of thyroid cysts – fluid-filled and complex. Fluid-filled cysts mainly consist of liquid and have a lower cancer risk. Complex cysts have mixed components of solid and liquid deposits. If a complex cyst is more than 50% solid, the risk of being cancerous increases. 

Cysts are one type of thyroid nodules. Others include colloid nodules, follicular adenomas, and thyroid cancers. Most of the thyroid nodules are not cancerous, but while fluid-filled cysts may simply require regular monitoring, a biopsy should be done for larger lumps. 

 

Thyroid Cyst Symptoms

Most thyroid cysts do not manifest symptoms, but as they grow larger, people may experience symptoms such as:

  • Difficulty swallowing
  • Hoarseness 
  • Problems breathing
  • Neck pain
  • Swelling 
  • Feeling a lump in the throat

If the cysts are associated with hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), you may experience symptoms such as nervousness and anxiety, hand tremors, fatigue, weight changes, irregular menstrual patterns, depression, and hair loss. 

Thyroid Cyst Causes

Thyroid cysts may result from various causes, including blocked ducts, hormonal activity, thyroid inflammation (thyroiditis), and iodine deficiency. In some cases, thyroid cysts are associated with conditions such as adenoma, hyperplasia, and thyroid carcinomas. 

Hyperthyroidism: Symptoms, Causes, and Treatments

Hyperthyroidism, also known as thyrotoxicosis, is overactivity of the thyroid gland, which results in overproduction of thyroxine hormone.

Thyroid Cyst Screening and Diagnosis

Thyroid cysts diagnosis helps determine whether they are benign or cancerous. There are various diagnosis and screening options available, including:

  • Physical screening: The doctor may request you to swallow, and then observe the thyroid area. If there are lumps on the thyroid, they will be visible as the gland moves up and down.
  • Blood tests: A thyroid function test can reveal the level of thyroid-stimulating hormone in the blood, indicating overactivity (hyperthyroidism) or underactivity (hypothyroidism).
  • Ultrasound: Imaging captures materials of different densities in varying shades, making it highly effective in detecting cysts.
  • Fine-needle aspiration biopsy: Biopsy is done hand in hand with ultrasound and involves inserting a small needle into the nodule to extract a sample of cells. 
  • Thyroid scan: Involves taking a radioactive iodine pill, and the doctor scans the thyroid as the pill passes. 

 

Thyroid Cyst Treatment

    Most thyroid cysts are benign and may resolve without treatment. The doctor may take different treatment approaches depending on the size of the cysts, symptoms, and risk factors (such as age and family history of thyroid cancer). Available options for managing cysts include:

    Monitoring

    Small thyroid cysts (usually 3 cm or less) may be benign. In this case, the doctor may leave the cyst and recommend regular monitoring through an ultrasound, probably once or twice per year.

    Aspiration

    Aspiration is a common initial treatment option for thyroid cysts. This involves draining the cyst through aspiration. However, the efficacy of this method depends on the percentage of the solid component, though the rate of recurrence is very high. 

    Surgery

    Surgery is not a common treatment option for thyroid cysts, but it is effective in removing the abnormal tissue. Mostly, it is used in cases where there are multiple large cysts, or the patient is experiencing symptoms. Thyroid surgery options may include thyroid lobectomy, thyroidectomy, or isthmusectomy. 

    When to Worry About Thyroid Cysts

    Thyroid cysts are not cancerous in most cases. However, some cysts may be malignant (cancerous), which requires proper diagnosis and treatment. You should be concerned if:

    • You experience thyroid pain
    • Cysts are large and fast-growing
    • You have difficulty swallowing or breathing
    • You experience symptoms of hyperthyroidism or hypothyroidism
    • You have a family history of cancer

    Thyroid Nodule Radiofrequency Ablation (RFA) Treatment

    Radiofrequency ablation aims to give patients a non-surgical option for treating thyroid nodules. This procedure is a minimally invasive option that a surgeon can perform, should the preliminary tests determine that you would benefit from it.

    The Advantages of RFA of Thyroid Nodules

    The major advantages of the technique are as below.

    1. It is done as day surgery procedure under light sedation.
    2. It takes about 45 minutes to one hour to complete the entire procedure.
    3. Patients are discharged the same day.
    4. Normal thyroid tissue adjacent to the nodule is preserved.
    5. It does not affect thyroid function.
    6. Multiple nodules can be treated at same time.
    7. The treated nodules do not regrow again.
    8. No surgical scar with needle mark on the skin.
    9. Quick recovery and back to full activity and normal lifestyle.
    10. The technique is suitable to treat even large thyroid nodules.

    Caring For Your Thyroid Health

    Have you ever experienced difficulty swallowing or breathing? You may have risk factors including a family history of thyroid nodules or iodine deficiency. Thyroid nodules are abnormal lumps (growths) within the thyroid gland, a butterfly-shaped gland located below your voice box. Even if most thyroid nodules are benign, 10-15% of nodules are cancerous. Sometimes overgrowth of normal thyroid tissue can lead to hyperthyroidism. In other cases, multiple nodules can form in the thyroid called multinodular goiter. Fluid filled thyroid cysts can be one type of thyroid nodule within the thyroid. More complex nodules may lead to thyroid cancers.

    Depending on the root cause and type of nodule you have, patients can monitor with regular ultrasound or even have a thyroid fine needle aspiration biopsy (FNAC) if required. Surgery to remove partial or whole thyroid gland can be done but thanks to minimally invasive treatments such as Radiofrequency Ablation (RFA), this procedure can treat noncancerous and cancerous thyroid lumps.
