How large does a thyroid nodule have to be for doctors to decide to operate. the thyroid blood tests came out negative. my thyroid is normal in size but i have a 2.2 x0.76x.99cm nodule on the right lobe and a .48 nodule on left. will the dr. decide to ope

Several factors: Routine labs are of little help when there is a mass. The workup of a nodule may include a scan; cold and hot nodules are more worrisome than warm ones. Since you are worried, consider a fine needle aspiration or otherwise getting tissue even if it is warm. Good luck.

Biopsy: The nodule should be biopsied (fine needle aspiration). If the biopsy is concerning, surgery is recommended. If the biopsy is negative, surgery is recommend for nodules that grow under observation or if the nodule is greater than 3 cm.

Yes, biopsy: If the report didn't say that this is a cyst, then you should get a fine needle biopsy. If negative, it can be followed with serial ultrasound as long as it is not causing problem swallowing or breathing now. If the mass grows on subsequent ultrasound, you can then re biopsy or just proceed with surgery. In any case, keep close eye on the mass, at least once/year with an ultrasound.
