For patients with thyroid cysts, it is necessary to first understand the patient's thyroid function, whether it is normal, overactive, or underactive. For patients with thyroid cysts who also have hyperthyroidism, a diet avoiding iodine is still necessary, as excessive iodine intake can significantly affect their hyperthyroid condition, therefore they need to consume iodine-free food. However, for patients with normal thyroid function or those with hypothyroidism, a normal diet is appropriate, and there is no need to avoid iodine. It is also recommended that they avoid smoking and alcohol in their daily life.

How should thyroid cysts be treated?

Thyroid cysts refer to fluid-containing sac-like formations found in the thyroid gland. For their treatment, thyroid cysts are a type of benign tumor of the thyroid. In imaging studies, if the nodule's diameter is less than one centimeter, it usually presents no clinical symptoms or signs. Regular follow-ups with thyroid ultrasonography and thyroid function tests are advised. If there is no trend of enlargement, continued observation without surgical intervention can be appropriate. However, if the nodule's diameter is greater than one centimeter, or if it is located on the surface of the thyroid, the local skin may show a protrusion or bulge, and the cyst may continue to grow, pressing on the trachea or even the esophagus, causing symptoms such as chest tightness, difficulty breathing, a feeling of swallowing, and obstruction. It is important to seek medical attention in a timely manner, undergo a fine needle aspiration biopsy if necessary, and surgical treatment may be required if needed.

What should I do about a thyroid cyst?

What should I do if I have a thyroid cyst? First, we need to understand what a thyroid cyst is. A thyroid cyst refers to a fluid-filled sac found in the thyroid gland. Generally, patients with thyroid cysts do not show any clinical symptoms in the early stages. Some discover a lump accidentally, usually without systemic symptoms. Individual patients may exhibit symptoms such as hyperthyroidism, and some with a longer disease course can also experience hypothyroidism, such as fatigue, poor appetite, constipation, and edema. Therefore, when diagnosed with a thyroid cyst, it is crucial to determine whether the cyst is benign or malignant and whether it affects thyroid function. If it does impact function, symptomatic treatment is necessary. Of course, most thyroid cysts are benign and can be monitored over time.

Is a grade two thyroid cyst serious?

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.

What causes thyroid cysts?

Thyroid cysts currently have no definitive cause identified. Previously, most believed they were possibly related to iodine deficiency, as such deficiency leads to thyroid hyperplasia and an increase in thyroid cysts. However, it was later discovered that in some high-iodine coastal areas, the incidence of thyroid cysts remains high. This suggests that variations in iodine levels, such as switches from low to high iodine or from high to low iodine, can also lead to the occurrence of thyroid cysts. Additionally, it is currently believed that there might be some connection with radiation and the use of mobile phones and computers, but there is no definitive conclusion. Regardless, once thyroid cysts occur, it is important on one hand to eliminate the possibility of malignant features, ruling out thyroid cancer, and on the other hand to ensure thorough thyroid function tests to understand if there are any abnormalities in function and whether treatment is needed.

What should I do if my thyroid cyst is painful?

Thyroid cysts generally do not have any clinical symptoms, but if untreated and continuously growing, there is a risk of hemorrhage within the cyst. Therefore, when a thyroid cyst becomes painful, it may be due to excessive internal pressure and bleeding inside the cyst, causing pain. At this point, it is necessary to go to the hospital emergency department for a comprehensive thyroid ultrasound to observe the size of the cyst, and to provide emergency surgical treatment or local puncture to aspirate the blood and relieve pain.
