Thyroid cyst
What should be paid attention to regarding thyroid cysts?
Thyroid cysts generally do not show obvious symptoms. When a cyst significantly enlarges or internal bleeding occurs, compressive symptoms or pain may appear. Thyroid cysts can lead to hyperthyroidism, and if persistent, may eventually cause hypothyroidism. Therefore, it is necessary to regularly monitor thyroid function to understand the status of thyroid activity. The treatment of thyroid cysts primarily involves distinguishing whether they are malignant. For thyroid cysts suspected to be malignant, surgical treatment is required. Generally, thyroid cysts are benign and only require regular observation and follow-up.
What are the symptoms of thyroid cysts?
Thyroid cysts generally refer to a cystic mass found in the thyroid, typically containing a mixture of fluid or semi-solid fluid. The mass usually has clear boundaries and is painless. It can move up and down with swallowing, which distinguishes it from some subcutaneous nodules. Thyroid cysts generally do not show obvious symptoms or clinical signs and are mostly discovered when looking in the mirror or during a physical examination. However, larger thyroid cysts may cause compression symptoms, such as pressing backward against the trachea or esophagus, leading to symptoms like breathlessness and discomfort swallowing. A small portion may also exhibit signs of thyroid dysfunction, such as hyperthyroidism or hypothyroidism, although this is relatively rare in clinical settings.
Which department to see for thyroid cysts?
For which department to consult for thyroid cysts, firstly if it is just a routine physical examination and a thyroid ultrasound reveals a thyroid cyst, it is recommended to first consult the endocrinology department. An assessment of thyroid function should be conducted to see if the thyroid is functioning normally or abnormally. If it is confirmed to be simply a thyroid cyst, then the size of the cyst should be considered in deciding the next steps for treatment. If the cyst is not large and thyroid function is normal, it might be advisable to observe it for some time. If the cyst causes symptoms due to compression, surgical treatment in the department of surgery might be necessary, or dealing with the thyroid cyst using techniques such as radiofrequency ablation could be considered. Therefore, it is advised to first visit the endocrinology department and, based on the opinion of the endocrinologist, if surgical intervention is needed, then consult the breast and thyroid surgery department.
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 foods are good for thyroid cysts?
For patients with thyroid cysts, it is necessary to check their thyroid function to understand their condition. For patients with hyperthyroidism, it is advised to avoid iodine-rich foods, such as seaweed, kelp, and seafood. However, patients with thyroid cysts are suggested to eat more foods that can enhance the immune system, such as shiitake mushrooms, mushrooms, wood ear mushrooms, walnuts, Chinese yam, and red dates. They can also eat some foods that help reduce nodules and swelling, such as spinach, mustard greens, and kiwifruit. Patients with thyroid cysts are advised to quit smoking and drinking, and avoid spicy and stimulating foods, such as chili peppers, Sichuan peppercorns, and onions. Additionally, they should avoid eating overly greasy foods.
Will thyroid cysts become malignant?
The formation mechanism of thyroid cysts may be due to the expansive growth of nodules, which compresses the venous vessels causing circulatory disturbances. This leads to tissue ischemia and atrophic degeneration, resulting in congestion and edema. Fluid accumulates to form cysts. Cysts formed through regressive changes in nodules can involve the entire nodule turning cystic or only partial cystic changes, thus forming masses that are partly solid and partly cystic. In thyroid cancer, cysts can also form due to necrosis, hemorrhage, and liquefaction. Therefore, thyroid cysts can also be cancerous. For this reason, regular observation and follow-up of thyroid cysts are necessary. If there is any indication of malignant transformation in a thyroid cyst, timely treatment is required.
