1. The relationship between thyroid nodules size and thyroid cancer
The size of thyroid nodules has little to do with thyroid cancer. nodules are smaller, and may also be micro-cancerous thyroid cancer.
But it is worth noting that if you find a solid thyroid tumor that increases rapidly in the short term, you should pay attention to it.
2. nodules require fine needle puncture biopsy ?
Fine needle aspiration biopsy is the gold standard for diagnosis of thyroid nodules (it is better not to do puncture). If a puncture biopsy is required. The following indications must be met:
1, the diameter of the nodule is greater than 1 cm;
2, the diameter is less than 1 cm, and there is a history of radioactive irradiation or contact with radiation contamination in childhood, a history or family history of thyroid cancer or thyroid cancer syndrome, ultrasound examination suspected malignancy, accompanied by abnormal ultrasound imaging of lymph nodes in the neck, positive PET-CT imaging, abnormally elevated calcitonin levels.
3. Is the thyroid nodule grown or not?
Ninety-tenths of thyroid nodules are benign, and generally does not require surgery . Blind surgery may cause the patient to be idle, and there will still be recurrence two or three years after the operation or cause other complications such as: hypothyroidism.
4. Will you get thyroid nodules when eating high iodine foods?
Iodine is the raw material for thyroid synthetic hormones, but iodized salt does not increase the risk of thyroid disease in Chinese people. (But must be appropriate )
Deep-sea fish , shellfish, etc. are not high in iodine content; dry plant-based seafood such as kelp and seaweed are mostly used to make soup and stir-fry, while iodine is afraid of high temperatures and will lose more than half of it during cooking, and you will basically not eat any amounts that are harmful to health. must take
. Do you need to check thyroid ultrasound every year?
During ordinary physical examination, there is no need for everyone to do thyroid ultrasound every year. Experts remind that the following three categories of patients should pay great attention to it:
- teenagers and children, thyroid disease will affect the development of height, intelligence, etc.
- Women of childbearing age and pregnant women will increase the risk of miscarriage and affect the health of two generations.
- 70-year-old elderly people are prone to increase the risk of atrial fibrillation, heart failure, etc.
You can have a thyroid ultrasound when you just entered the age of 70. If there is no abnormality and no related symptoms, you can check it every one or two years.
thyroid nodules TI-RADS classification diagnostic criteria
thyroid nodules TI-RADS (Thyroid Imaging Reporting And Data System) classification - generally can be divided into 0
to 6 levels (7 levels in total), and different levels have different diagnostic criteria.
0 is a result of ultrasound in suspected clinical cases without abnormalities, and additional examinations are needed;:
1 is negative, ultrasound shows that the gland size and echo can be normal, no nodules, no cysts or calcifications;
2 is benign, the risk of malignant tumor is 0%, and clinical follow-up is required;
3 is 80% likely to be benign, and the risk of malignant tumor is less than 2%;
htm Grade l04 is a suspicious nodule, and the possible proportion of malignant is 5~80%. It is necessary to combine clinical diagnosis.-4a malignant 5-10%;
-4b malignant 10-80%;
-4c malignant 30-80%;
5 grade cancer is highly likely, greater than 80%;
6 grade can be diagnosed as cancer and cytologic detection of cancer.
Ultrasound examination of thyroid nodules is a conclusion drawn based on the results of color ultrasound examination and the corresponding scores. Generally, 0
points are the corresponding category, 2 points correspond to 2 categories, 3 points correspond to 3 categories, 4-6 points correspond to 4A, 4B, 4C, and 7 points correspond to 5 categories.
