Thyroid nodules are masses inside the thyroid gland that can be differentiated from the thyroid. The most important feature of these masses is that they represent a thyroid cancer, albeit rare. For this reason, it is necessary to distinguish between benign formation and cancer in nodules with some features. This distinction can be made by pathological examination of the tissue sample taken by thyroid fine-needle aspiration biopsy (THNAB). The thyroid is an easily accessible organ located on the anterior surface of the neck, just under the skin. Thyroid cancers are also cancers that have a great chance of full recovery when diagnosed. Therefore, since the FNAB procedure is a relatively easy-to-apply procedure thanks to the widespread use of ultrasonography, it is a procedure that should be done without neglecting it when necessary.
Single nodules, nodules seen in individuals under 40 years of age and male gender, and nodules with some ultrasonographic features (nodule structure, ultrasonographic echo, calcification content and type, blood supply, borders of the nodule, etc.) are evaluated much more carefully. should be.
Although the cancer probability of nodules proven to be benign by aspiration biopsy is very low, it is not completely reset. For this reason, these nodules should be followed up periodically in terms of size, and in case of increased size, repeat biopsy. One of the most important points in this follow-up is that ultrasonography includes all three dimensions of the nodule in terms of volume measurement. Otherwise, size tracking of the nodule is not possible.
