How Long Do Thyroid Biopsy Results Take? Fast Facts!

Thyroid biopsies are a common procedure performed to diagnose thyroid nodules that may be a sign of thyroid cancer. A thyroid biopsy involves the removal of a small sample of tissue from the thyroid gland for analysis in a laboratory. The results of this procedure can provide patients and their healthcare providers with valuable information about any potential thyroid issues. If you’re considering a thyroid biopsy, you may be wondering about the timeframe for receiving your results. This article will provide you with fast facts about how long it takes to get your thyroid biopsy results, as well as everything else you need to know about this procedure.

What is a Thyroid Biopsy?

A thyroid biopsy is a procedure performed to diagnose thyroid nodules. Thyroid nodules are small lumps that sometimes form on the thyroid gland. Most thyroid nodules are harmless and don’t require treatment, but some nodules may be cancerous. A thyroid biopsy involves the removal of a small sample of tissue from a thyroid nodule for analysis in a laboratory to determine if it is cancerous or not.

How is a Thyroid Biopsy Performed?

There are three common types of thyroid biopsies: fine-needle aspiration biopsy (FNAB), core needle biopsy (CNB), and open biopsy. The most common type of thyroid biopsy is the fine-needle aspiration biopsy. This involves inserting a thin needle into the thyroid gland and withdrawing cells for examination under a microscope. Core needle biopsy, on the other hand, uses a larger needle to remove a small cylinder of tissue from the nodule. Open biopsy involves the surgical removal of the entire nodule.

How Long Does a Thyroid Biopsy Take?

A thyroid biopsy usually takes no more than 30 minutes to complete. The procedure is usually done under local anesthesia to numb the area, and it may be done with the help of ultrasound to guide the needle into the nodule. After the biopsy is complete, the tissue sample is sent to a laboratory for analysis. The length of time it takes to get your biopsy results will depend on a few factors.

How Long Does it Take to Get Thyroid Biopsy Results?

The time it takes to get your thyroid biopsy results will depend on a few factors, including the type of biopsy performed and the laboratory where the tissue samples are analyzed. In general, you can expect to receive your biopsy results within a week or two of the procedure. Some laboratories may provide results in as little as 24 hours, while others may take up to two weeks. Your healthcare provider can give you a better estimate of when to expect your results.

What Factors Affect the Timing of Thyroid Biopsy Results?

Several factors can affect the timing of your thyroid biopsy results:

  • The type of biopsy performed: Some biopsy types, such as FNAB, can provide results within a few days, while others, such as core needle biopsy, may take longer to process.
  • The lab turnaround time: The time it takes to process biopsy samples can vary depending on the laboratory’s workload and the complexity of the analysis required.
  • Doctor availability: The time it takes for your healthcare provider to review your results and schedule any necessary follow-up appointments can also affect the timing of your biopsy results.

What Happens After I Receive My Thyroid Biopsy Results?

After receiving your thyroid biopsy results, your healthcare provider will review them with you and discuss next steps, depending on whether the biopsy found cancerous or non-cancerous cells. If your biopsy results indicate cancer, your provider may recommend surgery to remove the affected tissue or other treatment options. If your biopsy results show non-cancerous cells, your provider may recommend monitoring the nodule over time or removing it if it’s causing symptoms or growing. Your healthcare provider will work with you to develop a treatment plan based on your individual needs.

What are the Risks of a Thyroid Biopsy?

Like any medical procedure, there are risks associated with thyroid biopsies. The most common risks include bleeding and infection at the biopsy site. Additionally, the procedure may cause discomfort or pain, although this is usually mild and short-lived.

What Should I Do to Prepare for a Thyroid Biopsy?

If you’re scheduled to undergo a thyroid biopsy, your healthcare provider will give you detailed instructions on how to prepare for the procedure. In general, you may be asked to:

  • Stop taking blood-thinning medications or aspirin a few days before the procedure
  • Fast for several hours before the biopsy
  • Inform your healthcare provider of any allergies you have or any other medical conditions you have


Thyroid biopsies are a routine and minimally invasive procedure used to diagnose thyroid nodules. Although biopsy results may take a week or two to arrive, they can provide essential information to help healthcare providers develop an appropriate treatment plan. If you have any concerns about your thyroid health or nodules, talk to your healthcare provider about the best diagnostic options for you.

Questions and Answers

  • Q: How do I know if I need a thyroid biopsy?
  • A: Your healthcare provider may recommend a thyroid biopsy if they detect a nodule during a physical exam, imaging study, or blood test that indicates an increased risk of thyroid cancer.

  • Q: Is a thyroid biopsy a painful procedure?
  • A: A thyroid biopsy is usually not painful and is performed under local anesthesia to numb the area. You may feel some pressure or discomfort during the procedure, but this is usually brief and mild.

  • Q: What should I expect during a thyroid biopsy?
  • A: During a thyroid biopsy, a thin needle will be inserted into the nodule, and a small sample of tissue will be removed for analysis in a laboratory.

  • Q: How long does it take to recover from a thyroid biopsy?
  • A: Recovery from a thyroid biopsy is usually quick and uncomplicated, and most people can return to their normal activities immediately afterward. You may experience mild pain or discomfort in the biopsy area for a day or two, which can usually be managed with over-the-counter pain medication.

  • Q: What happens if my biopsy results are inconclusive?
  • A: In some cases, biopsy results may be inconclusive, meaning that the tissue sample did not provide enough information to make a definitive diagnosis. If this occurs, your healthcare provider may recommend additional imaging tests or a repeat biopsy.
