Hello Mel,
welcome to the forum. We have a broschure on thyroid nodules. Are you able to read German?
Here is the part of the broschure that deals with diagnostics of thyroid nodules in English (my translation):
Nodules are suspect of malignancy when they are fast-growing and also when they cannot be moved during the palpation examination by the doctor.
Malignancy is suspected in particular if a combination of the following characteristics can be seen in the ultrasound:
hypoechogenic
microcalcifications
absence of rim(Halo sign)
irregular shape
increased blood circulation (hypervascularity)
changes in neighbouring lymph nodes
elastographically hard tissue
One characteristic alone is not sufficient to suspect cancer.
When individual nodules are larger than 1 cm, appear „cold“ in the scintigram or look susicious im the ultrasound, a fine needle aspiration shoud be performed for clarification.
End of quotation.
So, as you can see, you should definitely try to find someone to do a biopsy/fine needle aspiration.
Here is the link to the full text in German.
Broschüre: Knoten der Schilddrüse – Inhaltsverzeichnis
Maybe you can open a new thread with „search for doctor that does biopsy in … (region)“.
Best wishes,
Lotti
