Scared of a lump? Let's talk about the FNA test (Fine-Needle Aspiration)

Sometimes, small lumps or tumors appear under the skin in different parts of our body, right? It's very normal to feel a little scared and worried when you see something like that in a place like the neck, breast, or armpit. When you go to see a doctor at a time like this, he may tell you, "Let's take a small sample of this and see what it is." That's how a very simple, painless method used to obtain a cell sample from a suspicious lump is called a Fine-Needle Aspiration, or as we all know it, an FNA test.

Simply put, what is this FNA test?

Very simple. In short, FNA is a procedure that uses a fine needle to take a sample of cells, tissue, or fluid from a suspicious lump or lesion in your body. It's like taking a blood sample. Some people also call this a 'fine-needle biopsy'.

The sample obtained in this way is not just thrown away. It is sent directly to a lab. There, a doctor who specializes in cells, called a pathologist , examines the cells under a microscope. It is there that they find out exactly whether the cells are normal cells, whether they have an infection, or whether they are something dangerous, such as cancer cells.

What is the difference between FNA and Core Biopsy?

You may have also heard of a 'Core Biopsy'. Both are types of biopsies that use a needle. But there are some slight differences. Let's see what they are.

Simply put, FNA is like looking at a few words on a page of a book. Core Biopsy is like reading an entire chapter of a book. Your doctor will decide which of these two methods is best for you based on your situation.

In what cases is an FNA test performed?

FNA is used for two main purposes: for diagnosis and sometimes as a treatment.

For Diagnosis

This is the main purpose of the FNA test: to find out exactly what kind of lump or tumor it is.

• Find out if you have cancer .
• Find out if it is a boil caused by bacterial infections . For example, a pus-filled joint (septic arthritis).
• Make sure they are non-cancerous, such as cysts, fibroadenomas, or lipomas .

Although this test can be done on a lump anywhere on the body, it is most often done on areas like these:

• Breast
• Thyroid gland
• Lymph nodes
• Skin

Also, FNA can now be performed on organs located deep inside our bodies, such as the pancreas and lungs. For this, doctors use technologies such as ultrasound or CT scans to precisely guide the needle, performing this test very safely.

As a Treatment

Sometimes the FNA test is also used as a treatment.

• Remove pus from abscesses .
• Drain the fluid from the cysts and drain them.
• Remove fluid (seromas) that accumulate after some surgeries.

This way, the fluid is removed without a large incision, using only a thin needle, which can help prevent scarring, especially in areas that are important to the appearance of the body, such as the breasts.

How should I prepare for this test?

This is the best part. An FNA test usually doesn't require any special preparation . You don't need to stay in the hospital, and you can go home shortly after the test.

However, your doctor will give you clear instructions about this. The most important thing to remember is to tell your doctor about any other medications you are taking, especially blood thinners (anticoagulants) . You may be asked to stop taking these medications a day or two before the test.

What happens during the test?

This process is very quick and simple. It usually goes something like this:

1. You will be made to sit or lie down on an examination table.

2. The doctor or nurse will thoroughly clean the area where the needle will be inserted with an antiseptic solution.

3. Next, a small injection of local anesthetic may be given to numb the area. This will greatly reduce the pain you feel when the needle is inserted. It may feel like a small ant stinging you.

4. If the lump is deep inside the body, the doctor will use an ultrasound machine to guide the needle exactly where it should go.

5. Then, the thin needle is very carefully inserted into the lump and a sample of cells is obtained using a syringe.

6. It may be necessary to take more than one sample. If so, a new needle and syringe will be used each time.

7. When the work is finished, a small plaster or bandage is applied to the area where the needle was inserted.

The entire process only takes a few minutes, so there's no reason to be afraid.

Are there any risks after FNA?

FNA is a very safe procedure. However, as with any medical procedure, there are some very small risks that can occur. However, these are very rare.

• Minor pain and bruising: There may be some minor soreness and bruising at the injection site for a day or two. This is normal.
• Bleeding: Some people may experience some bleeding, especially in people with blood clotting disorders or those taking blood- thinning medications.
• Infection: There is a very small chance that germs will enter the needle site and cause an infection.
• Damage to surrounding tissue: When the needle is inserted, there is a very rare chance that the nerves or blood vessels around the lump may be damaged.

What kind of things might be included in the report I receive?

The lab report may contain several results. Your doctor will explain these results to you in simple terms.

• No abnormal cells: This means that the lump is normal and not dangerous.
• Abnormal and normal cells are mixed: If this happens, further tests may be needed to confirm the diagnosis.
• Precancerous cells: These are cells that are not yet cancerous, but have the potential to become cancerous in the future.
• Cancerous cells: If the lump is confirmed to be cancerous, your doctor will guide you on the next course of treatment.
• Evidence of a bacterial infection: If the lump is caused by an infection, medications such as antibiotics will be prescribed.

Sometimes, if the sample obtained is not sufficient, you may be asked to take another sample. Regardless of the result, do not panic and talk to your doctor to decide what to do next.

When should I see the doctor again?

There are usually no major problems after an FNA test. However, if you experience any of these symptoms, call your doctor immediately.

• If you get a fever
• If the needle insertion site is red, swollen, or pus is coming out
• If the pain increases day by day
• If there is an unexpected change in the lump (e.g., sudden enlargement)
