Thyroid Enlargement: Risks, Treatment Options, and Concerns

Goiter

My father-in-law is 70 years old and recently sought medical attention due to increasing swelling in his neck.
According to the doctor, he has a goiter (which is almost the size of a fist) and has recommended surgery.
However, he seems to be fearful of the surgery and insists that the swelling has been present since his twenties, thus refusing surgical treatment.
My questions are: Is there a possibility that this condition could turn into a malignant tumor? What additional tests should be conducted? If he insists on refusing surgery, what are the risks involved? I hope to receive your advice.
Thank you!

Dr. Xie Wenhuai reply Breast and Thyroid

Thyroid tumors can be classified as functional and non-functional, primarily based on the presence or absence of thyroid dysfunction.
If, as you described, your father-in-law has had the tumor since the age of 20 without any symptoms of dysfunction, it is certainly non-functional.
An ultrasound examination and a physical examination should be performed, as the tumor has already reached the size of a fist.
Surgical removal is recommended, as the procedure itself carries minimal risk, but his overall health status should still be assessed.

More Info

Thyroid enlargement, also known as goiter, can be a concerning condition, especially in elderly patients. In your grandfather's case, where the thyroid has grown significantly over the years, it is essential to evaluate the situation carefully. Here’s a comprehensive overview of the risks, treatment options, and concerns related to thyroid enlargement.

Understanding Thyroid Enlargement
1. Causes of Thyroid Enlargement: Thyroid enlargement can occur due to various reasons, including iodine deficiency, autoimmune diseases (like Hashimoto's thyroiditis or Graves' disease), nodular thyroid disease, or thyroid cancer. In some cases, it may be idiopathic, meaning the cause is unknown.

2. Risk of Malignancy: The risk of thyroid cancer in patients with goiter is generally low, especially if there are no concerning features such as rapid growth, firmness, or associated lymphadenopathy. However, the risk does increase with age and certain risk factors, such as a family history of thyroid cancer or exposure to radiation. It is crucial to assess the characteristics of the goiter through imaging studies and possibly a biopsy if there are suspicious nodules.

Diagnostic Evaluations
To determine the nature of the thyroid enlargement and assess the risk of malignancy, the following evaluations are typically recommended:
- Thyroid Function Tests: Blood tests measuring TSH, Free T4, and Free T3 levels can help determine if the thyroid is functioning normally, overactive, or underactive.

- Ultrasound: A thyroid ultrasound can provide detailed information about the size, structure, and composition of the thyroid gland. It can help identify nodules and assess their characteristics.

- Fine Needle Aspiration Biopsy (FNAB): If nodules are present, especially those that are larger than 1 cm or have suspicious features, a biopsy may be necessary to rule out cancer.

Treatment Options
1. Observation: If the goiter is benign and not causing any symptoms (such as difficulty swallowing or breathing), a watchful waiting approach may be appropriate. Regular monitoring with ultrasound and thyroid function tests can help track any changes.

2. Medications: In some cases, medications such as levothyroxine may be prescribed to suppress TSH levels, which can help reduce the size of the goiter, especially if it is due to hypothyroidism.

3. Surgery: Surgical intervention is usually considered if the goiter is causing compressive symptoms, is suspected to be malignant, or if there is cosmetic concern. The risks associated with surgery include bleeding, infection, and potential damage to the recurrent laryngeal nerve, which can affect voice quality.

Concerns Regarding Surgery
If your grandfather is hesitant about surgery due to fear, it is essential to address these concerns. Discussing the potential benefits of surgery, such as relief from symptoms and the reduced risk of malignancy, may help. Additionally, explaining the surgical procedure, recovery time, and the low complication rates associated with thyroid surgery can alleviate some fears.

Conclusion
In summary, while thyroid enlargement can be benign, it is crucial to evaluate the risk of malignancy and the need for treatment carefully. Diagnostic tests like ultrasound and thyroid function tests are essential in guiding management. If surgery is recommended, it is important to weigh the risks and benefits and consider your grandfather's preferences and concerns. Engaging in open discussions with his healthcare provider can help him make an informed decision about his treatment options.
