If a 6 x 3 mm nodule is found in the thyroid gland, if you want to remove it, you need to undergo an open surgery, or you can do a minimally invasive lumpectomy, where you enter the lumpectomy under the areola and have the nodule removed. However, the removal of thyroid nodules usually follows certain treatment principles, for example, if a patient with a thyroid nodule has a family history of thyroid cancer, the nodule will be more malignant in nature, or the thyroid nodule will grow significantly with each review, at this time it should be taken seriously and it is best to remove it in time. If the nodule is graded under ultrasound as well as its morphology, there is no very obvious malignant signal, for a nodule of 6×3 size, it can continue to be observed, and if the diameter is greater than 1 cm, surgical removal is recommended.
