Biopsy of the thyroid nodule / nodules, and scientifically, TAB (fine-needle aspiration biopsy of the thyroid nodule) is a very important procedure in the diagnosis of thyroid diseases, and in the diagnosis of thyroid cancer – the main one, since blood tumor markers for the primary diagnosis of thyroid cancer gland does not exist.
TAB is always performed under ultrasound control!
All nodes over 1 cm are biopsied, especially with a rapid growth of the node, which is +5 mm in six months. A biopsy is performed for differential diagnosis between pseudo-nodes in autoimmune thyroiditis and true colloidal nodes.
TAB is also used for therapeutic purposes – fluid is pumped out from a node or cyst, after which alcohol is injected (so that the node / cyst does not grow), the procedure is called alcohol ablation.
Preparation for TAB is not required, but it is advisable to eat a large meal 1.5-2 hours before the procedure.
As a result of TAB, a cytological study of a biopsy specimen (that is, the cellular composition of the node) is issued. The biopsy accuracy is 98%.
If you receive insufficient material (few cells) or if it is not informative, the procedure will need to be redone!
The biopsy can be done here:
on B. Sampsonievsky 45, Kolomyazhsky 28, Pushkarskaya 20, Siqueiros 7. In our MC, biopsy of nodes is successfully carried out with the size of formations from 3 mm and more.
The TAB procedure has its own myths and misconceptions that I would like to dispel.
Myth 1. – after a biopsy, the node begins to grow rapidly, it can turn into a malignant one.
Myth 2. The TAB procedure is painful.
Myth 3. Inserting a needle can damage the organs of the neck.
These fears are not true. Of course, you always have the right to refuse the procedure, but then you take responsibility for your health!
