Diet for thyroid nodules calcification
Patients with calcified thyroid nodules need to be cautious about their diet. Firstly, they should avoid irritating foods such as chili peppers, ginger, garlic, strong tea, coffee, and alcohol. Secondly, they should not consume foods high in fiber as these can cause diarrhea. Instead, they should eat foods rich in carbohydrates and fats, which provide energy and reduce the consumption of proteins in the body, as proteins play an important role in physiological regulation. Additionally, these patients should consume foods rich in vitamins and minerals to aid physiological metabolism. Lastly, it is beneficial for patients with calcified thyroid nodules to include animal organs in their diet.
The difference between thyroid enlargement and thyroid nodules
Thyroid enlargement generally refers to simple thyroid enlargement, which is typically diffuse thyroid enlargement, mainly caused by iodine deficiency, commonly seen in endemic goiter and physiological thyroid enlargement. Thyroid nodules, on the other hand, are nodular hyperplasia of the thyroid caused by certain physical and chemical factors. Thyroid nodules can manifest as benign hyperplasia or malignant hyperplasia. Therefore, the risks associated with thyroid nodules are relatively greater than those of thyroid enlargement. However, some patients with thyroid enlargement, as the disease progresses, can develop nodular hyperplasia of the thyroid. These are the differences between the two.
"Malignant thyroid nodules" means what?
Thyroid nodules are assessed under ultrasound with a grading system, and if rated at level three or higher, they tend to be more likely to be malignant. The most common malignancy in thyroid nodules is thyroid cancer. Among all types of tumors, thyroid cancer tends to grow slowly and is relatively less malignant. Therefore, if an ultrasound suggests a high likelihood of malignancy in a thyroid nodule, further examinations should be conducted. This can include a fine needle aspiration biopsy, thyroid contrast-enhanced ultrasound, or even direct surgical removal of the malignant nodule for further pathological examination to determine whether it is benign or malignant. Since the degree of malignancy of thyroid nodules is relatively low compared to other malignant tumors, a high grading score on a thyroid nodule should not be overly worrying. It is advisable to proceed with formal medical checks and regular follow-ups, as the five-year survival rate is quite high, exceeding 80%.
Are thyroid nodules serious?
The severity of thyroid nodules needs to be assessed based on their nature, size, function, and location. Generally, they can be classified into benign and malignant, with malignant nodules being thyroid cancer, which requires timely treatment. Surgical treatment is the main method for treating thyroid cancer, whereas most benign nodules do not require special handling. Regarding the size of the thyroid nodules, if the nodules are too large and compress surrounding tissues such as the trachea, esophagus, and nerves, surgical treatment is recommended. For common benign nodules, regular observation is sufficient. Functionally, some thyroid nodules may affect thyroid function, such as in Hashimoto's thyroiditis, which can present with diffuse multiple nodules, leading to either hyperthyroidism or hypothyroidism. In such cases, appropriate medication treatment is needed. From a positional perspective, ectopic growth of thyroid nodules, if located at areas like the base of the ear, pharynx, neck, esophagus, or thoracic cavity, is a rare congenital developmental anomaly. If such a nodule significantly enlarges and compresses surrounding tissues, surgical treatment is advised.
Does thyroid nodule puncture hurt?
Fine needle aspiration is an invasive examination, but it is currently an important and most efficient method for assessing benign and malignant conditions, generally conducted under ultrasound guidance. Thyroid nodule aspiration does not cause much pain, similar to that of an injection. Anesthetics are used during the procedure, so the pain is not very noticeable. However, as the effect of the anesthetic wears off, there may still be some pain at the puncture site, but the patients do not need to carry a heavy psychological burden.
Is thyroid nodule ablation a good treatment?
Thyroid nodule ablation has its advantages over traditional surgery, but it also has its shortcomings. The advantages include minimal trauma, less bleeding, and less pain for the patient. Ablation involves inserting an ablation needle through the skin of the patient's neck, directly into the tumor to perform the ablation with the goal of eliminating the nodule. Since it does not require cutting, it reduces damage to surrounding tissues and bleeding, allowing the patient to resume activities earlier and reduce suffering. However, the drawback is that ablation is effective for smaller benign thyroid masses, but for complex or malignant thyroid nodules, the treatment effectiveness is poor, and its use is not advocated.
Thyroid nodule biopsy pros and cons
Currently, thyroid nodule puncture is performed under ultrasound guidance, so it is relatively safe. Fine needle aspiration causes minimal damage to the thyroid and almost no complications occur. Generally speaking, the following few adverse reactions may occur: One is bleeding, because the thyroid is a blood-rich organ, so bleeding may occur post-puncture. It can be controlled by applying local pressure immediately after the puncture. The second is pain, which is generally mild and can be relieved within 1-2 days. The third is skin infection, which is more likely in patients who are obese, have numerous skin folds, and sweat easily. In such cases, antibiotic treatment may be necessary. The fourth is injury to the trachea and nerves, although this is very unlikely and typically resolves on its own.
What should I eat for thyroid nodules to dissipate?
Traditional Chinese Medicine (TCM) believes that thyroid nodules are mainly caused by emotional distress, dietary imbalances, and environmental maladjustment. Long-term emotions such as anger and depression can lead to stagnation of qi (vital energy), resulting in liver qi dysfunction and the formation of phlegm. Qi stagnation and phlegm accumulation in the front of the neck lead to the formation of this goiter. Therefore, the treatment for this condition often involves the use of foods or medications that soften hardness, disperse nodules, reduce swelling, and resolve stasis. For example, purslane, loofah, plums, and dried figs are some of the foods that can clear heat, facilitate diuresis, reduce swelling, and disperse nodules. Appropriate consumption of these foods can be beneficial in slowing the progression of the disease. However, it is generally difficult to dissolve nodules through diet alone, and active treatment is still necessary.
Symptoms of thyroid nodules
Thyroid nodules in the early stages often show no clear symptoms, with only small nodules appearing within the body. The size of these nodules can range from several millimeters to several centimeters, and their texture is generally slightly harder compared to the surrounding glandular tissue. When the enlargement is more noticeable, the nodule can move up and down with the thyroid gland during swallowing. In addition to the presence of nodules, when the thyroid nodule is prominent, it can compress the trachea, leading to difficulty breathing and irritative dry cough. If it compresses the recurrent laryngeal nerve, it may cause hoarseness, varying degrees of hoarseness, and even an inability to speak loudly. In patients with malignant nodules, the invasive malignant cells can cause symptoms such as hoarseness, difficulty breathing, dysphagia (difficulty swallowing), diarrhea, palpitations, facial flushing, and decreased blood calcium levels. If these symptoms occur, it is crucial to seek medical attention promptly.
Thyroid nodule examination checks what
Generally, when thyroid nodules are detected, one should visit the hospital's breast and thyroid surgery department or the endocrinology department. If you find a thyroid nodule, you can consult a doctor and undergo some relevant tests based on your specific situation. Typically, the following tests are conducted: 1. Thyroid ultrasound: This can determine the size, number, location, texture, shape, and edges of the nodules, including whether there is calcification. It also examines the blood supply within the thyroid nodule, the relationship with surrounding tissues, and assesses whether there are lymph nodes in the neck and the nature of these lymph nodes. 2. Blood tests are needed to measure thyroid function, particularly the level of Thyroid Stimulating Hormone (TSH). Higher levels of TSH indicate that the thyroid nodule is more likely to be proliferative, and thus, the risk of thyroid cancer increases. In addition, Thyroglobulin (Tg) can be measured. Another measure is Serum Calcitonin (Ct). If serum calcitonin is > 100 pg/mL, medullary thyroid cancer should be highly considered, as these cancer cells can secrete large amounts of serum calcitonin, causing this marker to significantly increase. Nuclear isotope imaging is also performed. If the nodule is large and TSH levels are low, a thyroid radionuclide scan is conducted to see if the nodule is a hyperfunctioning adenoma. When necessary, a Fine Needle Aspiration Biopsy (FNAB) is also performed. Fine needle aspiration is an invasive test, but it is currently an important and most efficient method to assess the benign or malignant nature of the nodule. It is generally performed under ultrasound guidance.
