Yes: The fna (fine needle aspiration) will gather a small sample of cells from the nodule, which will allow the pathologist to determine what kind of growth it is. Congrats on it being benign!

Cannot be certain: Follicular thyroid lesions can only be differentiated as mailgnant with surgery. When the specimen is reviewed by the pathologist if there is capsular invasion, vascular invasion, or lymphatic invasion then the diagnosis is follicular carcinoma and not follicular adenoma.

Can't tell: For a follicular neoplasm of the thyroid one cannot tell from a needle biopsy if it is a benign adenoma or a malignant carcinoma. At least this half of the thyroid needs to be removed for diagnosis.

Cytology: Looking at a cellular aspirate is the first line test for evaluating a thyroid nodule. It should be collected under ultrasound guidance to ensure the sample is from the nodule. The accuracy is 90%. If there are doubts, the sample slides can be reviewed by a reference expert cytologist. Additionally, molecular testing can be done on material obtained at biopsy or on the pathology slides.
