Thyroid cystic nodules over 1cm usually need to be examined to determine whether surgery is needed. Whether surgery is needed is not only determined by the size of the nodule, but also affected by a variety of factors such as the benign or malignant nature of the nodule and the patient’s clinical symptoms. Clinically, nodules larger than 1cm need to be followed up continuously so that changes in the nodule, such as compression symptoms or malignancy, can be detected and treated as early as possible. However, not all nodules larger than 1cm need surgery. For most of the nodules that are benign and have no special clinical symptoms such as compression, follow-up can be continued. 1. Benign and malignant: If the cystic solid nodule is malignant after examination, surgery should be arranged immediately to avoid the spread of cancer cells. If the cystic solid nodule is benign, the size of the cystic solid nodule and whether it compresses the trachea and esophagus should be taken into consideration. 2. Clinical symptoms: If the cystic solid nodule presses on the trachea and esophagus, causing difficulty in breathing and swallowing, surgical resection is needed. If there is no adverse reaction, surgical removal is not necessary, and regular review is sufficient. If cystic solid thyroid nodules are found, professional doctors need to judge whether surgery is needed according to the examination results and the extent of the disease. Therefore, timely examination and treatment are recommended to avoid delaying the condition.
