Thyroid cysts at Grade 2A are generally not very serious. If we consider supporting points for severity in the thyroid, finding one example is considered as first-level evidence, while finding one plus another one counts as second-level evidence. Generally speaking, once it reaches Grade 4A and above, attention needs to be paid as it suggests a malignancy, indicating a higher possibility of malignancy. If it’s below 4A, at Grade 3 and below, it typically suggests a greater likelihood of benign lesions. In such cases, it is recommended to follow up dynamically and definitely conduct an ultrasonic contrast examination.

Do thyroid cysts require a special diet?

Thyroid cysts refer to fluid-containing sacs that appear in the thyroid gland. Generally, these cysts do not become malignant, and they do not present any clinical symptoms, nor do they cause hyperthyroidism. If the cyst is particularly large and compresses the local thyroid tissue, it generally does not lead to hypothyroidism. Therefore, there is generally no need for a special diet for thyroid cysts. However, some scholars believe that the formation of thyroid cysts is related to iodine deficiency, or they can also occur in areas with high iodine content. Hence, it is advisable to avoid consuming foods with particularly high iodine content.

Precautions for Thyroid Cysts

If an ultrasound has confirmed a diagnosis of a thyroid cyst, it's important to manage iodine intake in your diet. You should not consume too much iodine, but also not completely avoid it; a normal, regular diet is sufficient. Secondly, it is important to monitor any changes in the size of the thyroid cyst. Regular ultrasound checks and self-examination can help observe if there's any rapid increase in size locally. If the cyst grows significantly and is accompanied by pain, it might indicate the risk of bleeding within the cyst. Normally, do not massage the thyroid cyst, as massaging will not have any beneficial effects.

Are thyroid cysts dangerous?

Generally speaking, thyroid cysts are benign lesions and are not dangerous. First, let's understand what thyroid cysts are. A thyroid cyst is a fluid-containing cystic formation found in the thyroid gland. Typically, the lump is round, smooth, painless, or may cause slight pain, and can move up and down with swallowing. Most cysts are solitary nodules, and it is less common to find multiple nodules. Additionally, if the cyst is large or if there is bleeding within the cyst, it can cause symptoms of compression such as pain, difficulty swallowing, difficulty breathing, and hoarseness. We know that about 10% of cystic nodules are malignant, hence, it is important to understand the nature of a thyroid cyst. If it is malignant, surgical removal is necessary. Furthermore, if the nodular cyst is large and causes compression symptoms, surgery is also required. However, most are benign lesions, and thyroid function is within the normal range, so no special treatment is needed, just follow-up observation. Therefore, whether thyroid cysts are dangerous depends on the circumstances.

Can thyroid cysts be treated with minimally invasive surgery?

When the cyst is smaller than 5cm, minimally invasive treatment can be used. Thyroid cysts are generally benign lesions and rarely become malignant. A thyroid cyst refers to a fluid-containing cystic structure in the thyroid, commonly known as a blister. This blister can be large or small, and is usually asymptomatic when small. For its treatment, when the cyst is smaller than 5cm, a minimally invasive procedure involving fine needle aspiration can be performed to withdraw fluid from the cyst, followed by the injection of anhydrous alcohol to close off the cyst cavity and prevent recurrence. However, if the cyst is larger than 5cm, surgical treatment is recommended for complete removal.

Do thyroid cysts require surgery?

Thyroid cysts are generally benign lesions and are typically classified as below 3B level in thyroid ultrasound grading, which means they are categorized as class 1, 2, or even 3. The decision to perform surgery depends primarily on the size of the thyroid cyst. If the cyst is large enough to cause compressive symptoms, then surgical treatment is necessary at that time. Secondly, if the development of the thyroid cyst is rapid, and fine needle aspiration of the thyroid reveals malignant changes, then surgery is also required. For routine thyroid examinations, if the thyroid cyst is relatively small, classified at a lower level, and there are no associated thyroid functional abnormalities, regular follow-up is generally sufficient without the need for surgical intervention.
