Would you like to know about a thyroid biopsy?

"Biopsy"! You might feel a little scared when you hear this word, right? That's normal. But, strictly speaking, this is just another important test that doctors use to diagnose diseases. Just like we do blood tests and X-rays. So today, let's talk about what a thyroid biopsy is, how it's done, and whether there's anything to be afraid of.

What is a thyroid biopsy? Simply put...

Think of it like this: Your thyroid is a small, butterfly-shaped gland in the front of your neck. It does a lot of important work for your body, especially the production of hormones that control your metabolism. A thyroid biopsy is a procedure that involves taking a very small sample of cells or fluid from your thyroid gland and testing it. This can help doctors diagnose certain thyroid conditions.

When is a thyroid biopsy performed?

Not all thyroid problems require a biopsy. Most of the time, the condition can be diagnosed with blood tests and imaging results. However, if your doctor finds thyroid nodules, they may suggest a biopsy.

Let's talk a little about thyroid nodules.

Now you may be wondering what thyroid nodules are. These are small, solid or fluid-filled lumps that form inside the thyroid gland. They look like little bumps on the body, don't they? That's right. The majority of these nodules are benign, meaning they are not cancerous. However, a very small percentage, between 5% and 15%, can be cancerous.

So, a thyroid biopsy can help your doctor find out exactly what caused the lump and whether it's benign or something to be concerned about. In particular, doctors are more likely to do a biopsy if the lump is larger than 1 centimeter (about 0.39 inches) .

How is a thyroid biopsy performed? What are the methods?

There are three main ways to do this biopsy. Let's take a look at what they are.

1. Fine-Needle Aspiration (FNA) method

This is the most common type of biopsy for thyroid nodules. This involves using a very fine, long needle (22-gauge or smaller) to remove a small amount of cells and fluid from a thyroid nodule or several nodules. When doing this, the doctor uses an ultrasound scan to guide the needle precisely into the nodule. This means that the scan guides the needle to the exact location. This is a simple procedure that does not require a large incision.

2. Core-Needle Biopsy (CNB) method

This is similar to the FNA procedure, but the needle used is slightly larger (14- to 20-gauge diameter). This method can be used if the doctor wants to take a larger tissue sample without damaging it . This method can be used if the sample obtained with the FNA is not enough or if more information is needed.

3. Surgical Thyroid Biopsy

This is a very rare procedure. If the samples taken with either FNA or CNB are inconclusive, or if more information is needed, a doctor may decide to perform a biopsy, a surgical procedure that involves making a small incision in the neck, reaching the thyroid gland, and taking a sample.

How do you prepare before a biopsy?

The preparation process may vary slightly depending on the type of biopsy you are having.

For needle biopsy (FNA or CNB)

• In most cases, unless your doctor tells you otherwise, you can eat and drink normally.
• However, if you have any medications you take daily (especially blood thinners), it is very important to ask your doctor if you need to stop them a few days before the biopsy.

For a surgical biopsy

If you are having a biopsy like this, your doctor will give you clear instructions on how to prepare for it. It is important to follow those instructions exactly.

The most important thing is that your doctor is the best person to advise you. If you have any questions or concerns, be sure to ask your doctor.

What happens during a biopsy? What to expect.

Most of the time, the biopsy is done using either FNA or CNB. We mentioned earlier that in rare cases, surgery may also be performed. Let's take a look at what happens with each of these methods.

Fine-needle biopsy (FNA or CNB)

These are usually outpatient procedures. This means you can go home the same day. Here are some steps:

1. First, you will be given a small injection (local anesthesia) to numb the area of ​​your neck. This will prevent you from feeling much pain.

2. Next, the doctor will place a small, handheld device called an ultrasound transducer on your neck. This will help you see exactly where the thyroid gland and the lump are.

3. Next, that long, thin needle we mentioned earlier is slowly passed through your skin and into the thyroid gland.

4. Then, a sample of fluid and tissue is carefully withdrawn. It is very important that you do not move at all during this time.

5. After the sample is taken, the needle is removed and a small plaster-like bandage is applied to the area where the needle was inserted.

6. Finally, the sample is sent to a cytologist for examination.

If you have more than one nut, you can repeat this process several times. The entire process should take about 10 to 20 minutes.

Surgical Thyroid Biopsy

We say this is something that is rarely done. This method is used when the results of either the FNA or CNB are unclear, or if more information is needed. This involves performing surgery and taking a sample of the tumor and/or tissue directly from the thyroid gland and sending it to the laboratory.

What are the side effects after a biopsy?

Minor side effects after a biopsy include some soreness and bruising where the needle was inserted. You can take over-the-counter pain relievers, such as acetaminophen (Tylenol®) or ibuprofen (Motrin®), to help with this discomfort.

Serious complications are rare, but in rare cases, the following may occur:

• Bleeding
• Infection
• Formation of something like a cyst.

If something like this happens, you should inform the doctor immediately.

What do the results of the biopsy report mean?

According to the American Thyroid Association, biopsy results can be divided into six main categories. Let's take a look at what each type means:

| Result Category | Meaning | General Next Step |

| :----------------------------- | :------------------------------------------------------------------------------------------------------------- | :--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

| Benign (non-cancerous) | The lump is not cancerous. This is the most common outcome (60%-70% of cases). | Usually "watchful waiting" and a repeat ultrasound scan in about 12 months. |

| Malignant (cancerous) | The tumor is cancerous. (5%-15% of cases). |Most likely, surgical removal is required. |

| Suspicious for Malignancy | There is a high chance of cancer. (Usually removed surgically). | Usually removed surgically. Sometimes additional tests (e.g. molecular profiling ) may be done. |

| Atypia of Undetermined Significance (AUS) or Follicular Lesion of Undetermined Significance (FLUS) | The cells are slightly abnormal, but it is not certain whether they are cancerous or not. (Can be cancerous in 5%-15% of cases). | A repeat biopsy, molecular testing, or possibly surgery. |

| Follicular Neoplasm or Suspicious for Follicular Neoplasm | This may or may not be cancerous (15%-30% of cases are cancerous). | Often, part or all of the thyroid gland is removed surgically for examination. |

| Non-diagnostic or Unsatisfactory | There are not enough cells in the sample, or for some other reason, it is not possible to reach a clear conclusion. (2%-10% of cases). | Usually a repeat biopsy , often done under ultrasound guidance. |

Although this table can give you a rough idea, it's best to talk to your doctor for exact details about your results.

How long does it take to know the results?

Most people get their biopsy results within a week, but sometimes this time frame can vary slightly depending on the lab's workload or if additional tests are needed.

If the results are abnormal, what do you do next?

Your doctor will explain the results to you and tell you whether you need treatment and, if so, what to do. Everyone's situation is different, so treatment will vary. But in general, here's what you can expect:

• Benign nodules:This is often done by "watchful waiting." That is, an ultrasound scan is done again in about 12 months to see if there has been any change in the tumor.
• Malignant nodules: These almost always have to be removed surgically.
• Suspicious nodules: These are determined whether or not to be surgically removed based on the results of additional tests such as molecular profiling .

When should you see a doctor?

After a thyroid biopsy, if you develop any of these signs of infection, tell your doctor immediately:

• If you develop a fever .
• If you feel cold and shivering (Chills).
• If the area where the needle was inserted or the incision was made is red, swollen, and pus-like discharge is coming from there .

If you have symptoms like these, it could be an infection, so it's important to seek treatment quickly.

Finally, the most important thing to remember!

It's normal to feel a little scared when you hear the word "biopsy." However, having a thyroid biopsy doesn't mean you have something serious. Just like X-rays and blood tests, a biopsy is just a tool that doctors use to diagnose a disease. The results give us very important information.

If you have a thyroid problem, finding it before it gets worse is your best chance for long-term health. So, if your doctor suggests a biopsy, don't be afraid to ask for it, get the information you need, and face it head on. You are not alone, and there are doctors who can help you.

So, I hope this information is helpful to you. If you have any questions, don't be shy and talk to your doctor!
