The Role of Fine-Needle Aspiration (FNA)
Fine-needle aspiration (FNA) is a common procedure to evaluate thyroid nodules. It involves using a thin needle to extract cells from the nodule, which are then examined under a microscope. FNA helps determine if the nodule is benign or malignant, guiding further treatment decisions.
What Happens After an FNA?
Once the FNA is performed, the results fall into categories like benign, indeterminate, or malignant. If the results are indeterminate, further testing or a repeat FNA might be required. This helps clarify the nature of the nodule and whether surgery is necessary.
When to Consider Surgery
Surgery is typically considered if the nodule shows suspicious features or if molecular testing suggests a high risk of cancer. Diagnostic lobectomy, which involves removing part of the thyroid, may be recommended to obtain a definitive diagnosis. This approach minimizes unnecessary surgeries while ensuring thorough evaluation.
