Dandelion does not treat thyroid nodules. There is no clear and reliable evidence that dandelion can treat thyroid nodules, and the current attitude toward the treatment of thyroid nodules is that no medication is needed. Thyroid nodules are usually characterized first, and if they are benign nodules, there is usually no need for medication or surgical intervention, unless the nodule is particularly large and has affected the patient’s breathing or swallowing, or has seriously affected the patient’s appearance and social communication, at which point surgical treatment of the nodule is considered, usually without medication before surgery. In the case of malignant nodules, surgical intervention is required. The ultrasound characteristics of thyroid nodules before surgery are mainly based on the growth rate of the nodule, such as whether the nodule grows very fast in the short term, or whether the nodule grows longitudinally, usually with an aspect ratio of >1, or whether the nodule has gravel-like calcifications instead of coarse calcifications, which are mostly benign nodules with very hard texture, unclear nodule borders, or between the nodule and the surrounding If the nodule is hard, the nodule has unclear borders, or the nodule grows together with the surrounding soft tissues, especially the anterior cervical band, or if there are enlarged lymph nodes outside the nodule, especially multiple enlarged lymph nodes in the neck, then the nodule is more likely to be malignant. It is also necessary to consider the family history of the patient, such as whether the parents, brothers or sisters have a history of thyroid cancer, and whether the patient has a history of ionizing radiation, to make a comprehensive judgment.
