Thyroid nodules are a common thyroid disorder. With the popularity of physical examinations, the detection rate of thyroid nodules has increased significantly, and more and more patients with thyroid nodules are seen in outpatient clinics. A thyroid nodule is an abnormal growth of localized thyroid cells resulting in one or more abnormal tissue masses in the thyroid gland. It is commonly understood as a lump in the thyroid gland. Most thyroid nodules are benign and a few are malignant. We often encounter patients with thyroid nodules, mostly women, who are found to have thyroid nodules during a physical examination and are very worried, asking if the disease is serious and needs to be treated. There are also patients who do not take this disease seriously, thinking that it is silent, symptomless and will not affect their bodies. This shows that there is a great lack of understanding of thyroid nodules. Clinically, there are many diseases that can occur in the thyroid gland, one of which is thyroid nodules. The thyroid gland is divided into two lobes, the right and left, connected by an isthmus, like a butterfly in the neck, located in front of the trachea, below the thyroid cartilage, whose main function is to produce thyroxine, which has important functions to promote metabolism, growth and intellectual development. Thyroid nodules may be thyroid tumors, thyroid cancer, etc. They are generally referred to collectively as nodules when the nature of the nodule is not determined. Therefore, the impact of thyroid nodules on your health is self-evident. According to statistics, thyroid nodules can occur in 4 out of every 100 adults. A thyroid nodule is a common clinical condition in which a lump appears in the thyroid gland and can move up and down with the thyroid gland following swallowing movements. I heard from a colleague in the physical examination department that a corporate unit came to the hospital for a physical examination and more than 20 out of 100 people were found to have thyroid nodules, most of whom were previously unaware of them. Had it not been for the checkup, they might not have known why they were sick until their condition became severe. Therefore, early detection of thyroid nodules is crucial. What are the ways to detect thyroid nodules? Examination methods for thyroid nodules Most clinical examinations for thyroid nodules use ultrasound examination of the thyroid gland, thyroid nuclear scan, neck X-ray examination, thyroid fine needle aspiration cytology, and thyroid function measurement, which can clearly reveal whether thyroid nodules are present. Ultrasound of the thyroid gland can show solid, cystic or mixed nodules. A single solid nodule is more likely to be malignant, a mixed nodule is also likely to be malignant, and a simple cystic nodule is less likely to be malignant. Thyroid nucleus scans are classified as “hot” or “cold” nodules based on the nodule’s ability to take up radionuclides. “Hot nodules are functionally autonomous thyroid nodules and are almost always benign. “Cold nodules have the potential to be cancerous, but multiple cold nodules are mostly benign adenomas or nodules, and if there is bleeding or cystic changes in the nodule, it may also appear as a cold nodule. If there are small or sand-like calcifications on the nodules, they may be the sand bodies of papillary carcinoma. Large, irregular calcifications can be seen in degenerative nodular goiter or thyroid cancer. If infiltration or deformation is seen in the tracheal image, it suggests a malignant lesion. Do thyroid nodules require surgery? The first step is to determine the benignity or malignancy of the thyroid nodule. Surgery is preferred for malignant nodules; surgery is not required for benign nodules and regular follow-up in the endocrinology clinic is sufficient. However, surgery is needed when there are symptoms of respiratory pressure and hyperthyroidism. If the nodule is cystic and the possibility of malignant lesion is excluded, it can be treated by transdermal alcohol injection, but the recurrence rate is high. Can benign thyroid nodules become malignant nodules? Most thyroid nodules are benign, with malignant nodules accounting for 10-15% of cases. Not all benign nodules become malignant, but malignant tumors can develop from benign nodules, so even if you are diagnosed with a benign thyroid nodule, you still need regular outpatient follow-up. How to stay away from thyroid nodules 1. Control your emotions Emotional ups and downs can seriously affect the secretion of thyroid hormones, which can lead to hyperthyroidism and thyroid disease. Therefore, it is important to maintain a peaceful state of mind in daily life. The amount of iodine intake will directly affect the occurrence of thyroid disease. Too much iodine can lead to hyperthyroidism; too little iodine can lead to goiter. Generally speaking, patients in highland areas and mountainous areas are often iodine deficient and should be supplemented with iodine in appropriate amounts, while residents in coastal areas should control their iodine intake. 3, avoid overworking overworking will increase the burden on the thyroid gland The thyroid gland is in an unstable state and is prone to lesions. Therefore, it is important to combine work and rest and maintain a healthy lifestyle and work style. 4, away from pollution External environmental factors, such as air, soil, water and harmful chemicals in food can stimulate the thyroid gland and cause thyroid disease. Therefore, to prevent the occurrence of thyroid disorders, it is necessary to stay away from harmful chemicals.
