It seems as though every facility handles things differently, however, I agree just because of the size of the nodule (bigger than 1.0 cm) it is usually recommended that you get an FNA. That does not mean that it is cancer though. It just needs to be ruled out. If you are not comfortable with your GP, I would ask for a referral to an endo or go on your own if you do not need a referral.
I was wondering why they are sending me for the iodine uptake scan instead of right over to a FNA? I also wondered why the ultrasound read was so basic...I wish they would have had more descrtiptions like the others I have read about. My GP says she can handle this at this point and I don't need a specialist - however - I am not so sure. All in all, no matter what, I really want this lump out of my neck!!
Based on the size of the nodule, you could be advised to have FNA biopsy.
For some reason the description of solid nodule does not mention if it is iso- or hypoechoic, so if it is not hypoechoic it has LOWER chances to be malignant.
As long as report is not saying INCREASED Doppler color flow, it also means the good chances it benign. If the nuclear scan would indicate that the nodule is cold it could be monitored, ethanol injected or removed surgically if it causes some symptoms.
The mildly elevated TSH level calls for T3 T4 and TPO antibodies testing to look for the thyroid hormone level and/or the autoimmune condition.
