Do all thyroid nodules require a fine needle aspiration biopsy?

No: Nodules less than 0.8 CM generally do not need further evaluation with fna (fine needle aspiration). Nodules 1.5 CM or greater should usually be checked with an fna. For intermediate nodules, those between 0.8 and 1.5 cm, a doctor may consider the appearance of the nodule, and other risk factors in deciding whether or not to recommend an fna.

No, but: That's a very complicated question. The short answer is no, but the nuances of which thyroid nodule to biopsy and when are complex and beyond the context of this forum.

Agree with Dr. Whitman. According to guidelines published by Society of Radiologists in Ultrasound (SRU), and American Thyroid Association (ATA), a thyroid nodule less than 1 cm in diameter does not require a biopsy. However, from my perspective, the nodules' internal architecture, as seen on ultrasound images, is far more revealing than size.

Almost all: Fna is fast and informative way to evaluate thyroid nodules. Fna is recomended to undestand the morphology of the nodule: benign or malignant before treatment.

Usually Yes.: Fine needle aspiration biopsy is relatively easy procedure and it can give a lot of information whether cancerous or non-cancerous. If nodule is cancerous, it may classify the cancer such as; papillary, follicular, medullary or anaplastic type etc. Each may have different approach of treatment. If nodule is benign or reactive, you may not need further treatment. Follow up could be a recommendation
