In general, the nodules [except "hot"] larger then 1 cm are biopsed; however if you will repeat the ultrasound and the nodules will be same size, you may postponje biopsy.If, on the other hand, the nodules are growing the biopsy is necessary.
thanks, should I let them do the FNA? is it dangerous or worth while because he said hes doing it to find out if im going hypo or hyper......
The scan can show cold or hot area of about 3 mm, the ultrasound shows features about 2mm size. If the nodules did not show on the RAIU scan image the nodules are "warm" that means they can be composed from normal but overgrown thyroid tissue, most likely benign.
The biopsy will not show if you are going hypo or hyper; TSH and T4 tests are show that.
