Is surgery recommended if thyroid fna results are follicular lesion of undetermined significance? should i get second fna?

No second FNA: There is a 15% chance of malignancy with a flus lesion so talk to your endocrinologist.

Yes: A follicular lesion identified on fine needle aspiration generally does warrant a thyroid lobectomy because a follicular cancer can not be ruled out. The architecture of the tissue is necessary to distinguish a benign from a malignant follicular lesion, and this can not be obtained with an fna. Repeat fna will not help.

Depends on size, age: Follicular cells are also found in normal thyroid. However, when the fna shows.
