Thyroid nodules cannot heal on their own, but with appropriate treatment, good recovery can be achieved.

Thyroid nodules are a common clinical disease, with many causes. Nodules can be either solitary or multiple, and the incidence of multiple nodules is relatively higher. Regardless of the cause, thyroid nodules are more common in middle-aged women, with the most common symptoms including thyroid enlargement, neck discomfort, and localized thyroid pain.

When people are diagnosed with thyroid nodules, there is no need to be overly worried. If the color ultrasound and thyroid function tests show no abnormalities, it is possible to observe the condition dynamically, with a follow-up check about once a year. If there is a high suspicion of malignant nodules, it is advisable to opt for early surgical removal, which typically yields very satisfactory results.

Is thyroid nodule calcification scary?

Thyroid nodule calcification is a common disease of the human thyroid gland. When seeing thyroid nodule calcification, we should not be afraid. Thyroid nodule calcification refers to the dense proliferation of thyroid cells, which, during an ultrasound examination, appears as strong spots, specks, or rings on the thyroid. Thyroid nodule calcification can be divided into coarse calcification and microcalcification. Generally, coarse calcification is benign, and we can continue to observe it. If it is microcalcification, we can conduct a pathological examination. If it is malignant, surgical treatment can be performed; if it is benign, we can continue to observe. Therefore, thyroid nodule calcification is not something to be afraid of.

Differentiation between benign and malignant thyroid nodules

Generally speaking, whether benign or malignant, thyroid nodules show blood flow signals. For benign nodules, blood flow signals can be seen around the perimeter, with internal blood flow no different from normal thyroid tissue. In such cases, the nodules are typically diagnosed as thyroid adenomas, and they usually appear round or oval in shape with a uniformly echoic internal substance. If liquefaction occurs, mixed or cystic changes can appear; the tumor’s capsule tends to be intact, with clear boundaries. If a nodule has abundant internal blood flow with disorganized vessel distribution and high flow velocity, showing a high-resistance flow pattern, and has relatively less peripheral blood flow, it generally needs to be assessed for thyroid cancer. These nodules are often hypoechoic with irregular shapes, and the ratio of their longitudinal to transverse diameter is greater than 1. They have unclear boundaries, lack a capsule, and have no halo. In typical cases, microcalcifications like sand grains can also be observed. From the above analysis, we can see that the blood flow signals in thyroid nodules are complicated and reflect the extent of the nodular pathology. These signals can help in differentiating benign from malignant nodules, but when a rich and disorganized blood flow is observed, the nodule is more likely to be malignant.

Which is more serious, pulmonary nodules or thyroid nodules?

It is impossible to compare the severity between thyroid nodules and lung nodules. Firstly, thyroid nodules and lung nodules occur in different organs. Lung nodules are mostly caused by inhalation of dust, pollutants, or smoke. Thyroid nodules, on the other hand, often result from genetic factors, or issues with the patient’s own constitution leading to the formation of these nodules. Most lung nodules can be classified as benign or malignant through diagnostic tests, whereas it is often difficult to assess the nature of thyroid nodules with standard tests. Additional auxiliary examinations, such as PET-CT or SPECT, and biopsy pathology are needed to determine the nature of thyroid nodules. Therefore, the approaches to observing and handling these two types of nodules are entirely different, and they cannot be compared.

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.

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.
