Most cystic solid thyroid nodules are benign and are usually not dangerous. If the nodule is large, it may cause the danger of swallowing and eating, and difficulty in breathing. 1. Impact on swallowing and eating: The enlargement of cystic nodules in the thyroid gland and the compression of the esophagus in the throat will affect swallowing and eating. At first, there will be a feeling of obstruction when swallowing, and as the compression intensifies, it may lead to dysphagia, difficulty in swallowing solid food and other problems. At this time, timely surgical resection is needed to eliminate the compression of the esophagus. 2. Lead to breathing difficulties: cystic nodules of the thyroid gland may cause compression of the trachea, and may also lead to abnormalities of the epiglottis cartilage and vocal cords, which may lead to breathing difficulties, choking and coughing. At this time, timely surgical treatment is also necessary. 3. Malignant tumor metastasis: for malignant thyroid cystic nodules, tumor metastasis such as lymph nodes may occur. Therefore, if there is a high suspicion that cystic thyroid nodules are malignant, early surgical treatment is needed to avoid metastasis. After the discovery of cystic solid nodules in the thyroid gland, it is necessary to consult a doctor in a timely manner, follow the doctor’s instructions for examination and treatment, and do not leave it unattended to avoid the development of the disease.
