Can thyroid fine needle aspiration spread tumor?

Fine needle aspiration of thyroid gland is a clinical procedure in which the cells in the thyroid mass are aspirated by a fine needle, and then the aspirated cells are evenly spread onto a slide for examination under a microscope, so as to diagnose the thyroid mass from the perspective of pathology. Fine needle aspiration cytology of thyroid gland is simple, easy to perform and accurate. It is mainly used in the differential diagnosis of thyroid nodules and the differentiation of benign and malignant lesions. In addition, it has high specificity for the diagnosis of chronic thyroiditis and subacute thyroiditis.

Some patients are concerned that fine needle aspiration of thyroid nodules may lead to tumor spread. In fact, this fear is unnecessary. Fine needle aspiration of thyroid nodule selects a very fine needle. Fine needle aspiration adopts suction material, and the absorbed tissue is hidden in the needle core due to negative pressure. It won't leak out and contaminate other levels of tissue. Up to now, there has been no report on the use of fine needle aspiration in thyroid nodules. So you don't have to worry about the tumor spreading.
