Thyroid nodules grade 3 usually do not disappear on their own, but the risk of malignancy is relatively low, with a malignancy rate of <2%. At present, the TIRADS classification standard is used to evaluate the benign and malignant of thyroid nodules, which can be divided into 6 grades in general, and grade 3 thyroid nodules belong to benign nodules, with low risk of malignant transformation, but after the appearance of thyroid nodules, they usually do not disappear on their own. If grade 3 thyroid nodules do not affect normal life, there is no need for too much treatment, as long as regular checkups are conducted to avoid deterioration of the condition. If a grade 3 thyroid nodule is large enough to affect the patient’s normal swallowing and breathing, it can be removed surgically. If the patient has a grade 3 thyroid nodule, it is necessary to consult a doctor in time to find out the cause of the disease and take corresponding treatment, so as to avoid delaying the best time for treatment.
