There are more clinical cases of thyroid nodules, and the treatment plan is still to combine the type of lesion of the nodule with follow-up review or oral medication or surgery. First, the nature of the nodule is generally determined through thyroid ultrasound and other examinations. If the examination shows a cystic nodule, it is still considered a benign lesion, and if the cyst is not particularly large, a follow-up examination can be considered. If the cyst is relatively large and has a compressive effect on the surrounding tissues, with chest tightness and breath-holding, surgical treatment can be considered. If the examination shows cystic nodules or solid nodules, we should consider whether there is malignant change, firstly, through examination, and for some suspicious cases, we can consider pathological examination through biopsy, and confirm the diagnosis through pathological examination. For malignant nodules, surgical treatment should be performed to remove the diseased tissue and then choose the appropriate radiotherapy plan according to the later pathological examination. In addition to the above recommendations, daily attention should be paid to protecting the thyroid gland, minimizing external stimulation, eating a light diet, controlling iodine intake, and avoiding the stimulation of alcohol and tobacco to stabilize the condition as much as possible.
