Are you scared of a lump? Let's learn about the FNAC test (Fine Needle Aspiration)

Are you scared when you find a small lump or tumor somewhere on your body? Especially when you find a lump like this in a place like your neck, breast, or armpit, it is very normal to feel a lot of fear and anxiety, wondering, 'Is this cancer?' But the most important thing we need to remember is that not all lumps that form on the body are dangerous cancer cells. So, the FNAC that we are talking about today is a very simple, painless, and quick test that doctors use to find out exactly what this lump is and whether it is dangerous or not.

Simply put, what is this FNAC test?

The full name of FNAC is Fine Needle Aspiration. This is actually a type of biopsy . A biopsy is when a piece of tissue is taken from our body and examined. This is what happens in FNAC. Simply put, a very thin needle (just like a blood test needle) is inserted into a lump or cyst in your body and a small sample of cells is sucked into a syringe. This cell sample is then sent to a lab and examined under a microscope to see what kind of cells they are. Based on the report from this test, your doctor will be able to accurately determine whether the lump is cancerous, a normal fatty tumor, a fluid-filled cyst, or something caused by another infection.

In what cases does a doctor recommend performing an FNAC?

FNAC is most often performed for lumps or swellings that are usually felt under the skin. You may find a lump like this yourself, or a doctor may see it when you are examining you. Sometimes, lumps inside the body can be found with various scans. For example:

• CT scan
• Mammogram - especially during breast examination
• Ultrasound scan

If a scan like this shows something unusual deep inside the body, an FNAC can be performed to find out exactly what it is. Sometimes, FNAC is performed in conjunction with an endoscopy to reach a lump deep in the chest or abdomen. There, a tube with a camera attached is inserted into the body and a needle is passed through it to take the sample.

How should you prepare before the test?

This is a very simple test, so there is no need for much preparation. However, it is very important to follow your doctor's instructions exactly. Usually, they say things like this:

• Medication Information: If you are taking blood thinners such as aspirin , warfarin , or clopidogrel, you may be asked to stop taking them a few days before the test. Never stop taking your medication without first talking to your doctor.
• Food and drink: You may be asked to refrain from eating or drinking for a few hours before the test. This is especially important if you are given sedating medication.
• Someone to help: If you are given a medication that makes you feel a little sleepy, it is essential that you bring someone with you to take you home after the test.

What actually happens during an FNAC?

Most FNAC tests are performed on an outpatient basis and take less than 10 minutes, so there is no reason to be afraid.

What happens step by step:

1. Cleaning: First, the skin around the needle insertion site is thoroughly cleaned with an antiseptic. 2. Numbness: Next, a small injection of numbing medicine may be given to reduce the pain felt in that area. After this, you may not even feel the needle being inserted. 3. Scanning: Sometimes, an ultrasound scan is used to find the exact location of the lump. The doctor can see the needle being inserted into the lump while looking at the scan, so the test can be done very accurately. 4. Taking the sample: Then, a thin needle attached to a syringe is inserted into the lump through a hole in the skin. The vacuum created inside the syringe sucks some of the cells or fluid from the lump into the syringe along the needle. This takes a few seconds. 5. The test is complete: After the sample is taken, the needle is removed and a small plaster is applied to the area. That's it. Sometimes the sample is examined under a microscope on the spot to make sure it's a good sample. Or it's sent to a lab for further testing.

What happens after the test?

Unless you have been given medication to make you sleepy, you can go home normally after the test. If you are given medication, you may feel sleepy and sluggish for a while. Where the test is performed:

• It may swell a little.
• You may feel a little pain.
• It may be blue, like a bruise.

These things usually subside within a day or two. If you are in pain, you can take a common painkiller like Paracetamol. However, do not take other painkillers (especially aspirin) without asking your doctor. It can take about a week to get the final report of the test. Sometimes a preliminary report may be received earlier.

Are there any risks or complications with this?

FNAC is a very safe procedure , and serious complications are rare.

• Bleeding: A small amount of bleeding under the skin may occur, causing swelling and bruising (hematoma). This usually heals on its own in a few days.
• Infection: The risk of infection is very low because sterile equipment is used every time the test is performed.

Therefore, do not be unnecessarily afraid of an FNAC test. This is a very important and safe step to accurately diagnose your condition. FNAC, Fine Needle Aspiration, biopsy, lump, tumor, cancer test
