Thyroid nodules 0.89 x 1.02 are usually measured in centimeters. Whether a nodule is serious or not needs to be determined based on TIRADS grading and biopsy results. If the nodule is benign, it is usually not important; if it is malignant, it is usually more serious and requires prompt treatment. If the nodule is TIRADS 2 or 3, if there is no obvious pressure symptoms, usually no treatment is needed, only need to regularly review the thyroid ultrasound to understand the changes of the nodule; if there are pressure symptoms, then need to be treated by radiofrequency ablation or surgery. For TIRADS 4 or 5 nodules, if the diameter of the nodule is large, the doctor will usually recommend the patient to undergo fine-needle puncture, and choose the treatment plan according to the result of the puncture. If the nodule is benign and has no pressure symptoms, no treatment is usually needed. If the benign nodule is accompanied by pressure symptoms, or if the biopsy result is malignant, ablation or surgical treatment is needed. Therefore, the discovery of thyroid nodules, should be further endocrinology consultation, improve the thyroid ultrasound, if necessary, do the thyroid nodule pathology tissue examination, clear the nature of the nodule, in order to determine the condition.
