Thyroid Fine-needle Aspiration Biopsy


Thyroid fine-needle aspiration biopsy is a procedure to remove tissue and fluid from a nodule (lump) in the thyroid gland. This test helps your healthcare provider diagnose thyroid cancer or identify thyroid nodules that are not cancer. Your healthcare provider uses the results to decide whether you need additional treatment.



  • Place a cold compress or ice bag on your neck to ease swelling and discomfort. Ask your healthcare provider how long and how often to do this. Any swelling and bruising should go away after several days.
  • Ask your healthcare provider when you can return to your normal activities.

Follow up with your endocrinologist as directed:

Write down your questions so you remember to ask them during your visits. Keep all appointments for other tests or procedures ordered for you.

  • You have discomfort or pain at the site of the biopsy.
  • You have a bruise or a purple, swollen lump at the site of the biopsy.
  • You have questions or concerns about your condition or care.

  • You have sudden trouble breathing or shortness of breath.
  • You have more pain, swelling, and bruising in your neck along with a fast heart rate and pain when you speak or swallow.
  • You have sudden swelling at the biopsy site. If this happens, apply pressure and seek care immediately.
