A lump in the neck should first be examined with a color ultrasound of the neck. This is because the most common sources of thyroid disease are benign and malignant tumors. Benign tumors specifically include adenomas of the thyroid, simple thyroid cysts, and nodular goiter. Patients who have a significant sensation of gas pressure should promptly opt for surgery. If there are no clinical symptoms, they can be followed up and observed regularly, and they should pay attention to iodine-containing food supplementation. For malignant tumors of the thyroid gland, which manifest as pre-cervical masses, hard texture, poor mobility, and also prone to metastasis of cervical lymph nodes, early diagnosis without contraindication should promptly choose radical resection surgical treatment, and thyroxine replacement therapy should be performed after surgery.
