FNAC Test: Purpose, Procedure, Preparation, and Results

If your doctor has advised an FNAC test, you may be feeling anxious, especially if you have noticed a lump somewhere in your body. Understanding exactly what the test involves takes away much of that fear. At Orthomed Hospital Hisar, FNAC is a routine, quick, and minimally invasive diagnostic procedure that provides crucial information to guide your treatment.

What Is an FNAC Test?

FNAC stands for Fine Needle Aspiration Cytology. It is a diagnostic procedure in which a thin needle is used to extract a small sample of cells from a lump, mass, or swollen lymph node. These cells are then examined under a microscope by a pathologist to determine whether the growth is benign (non-cancerous), malignant (cancerous), or inflammatory.

FNAC is one of the simplest and most reliable first-line tests used to evaluate a lump anywhere in the body—most commonly in the neck, breast, thyroid, armpit, or groin.

Why Is FNAC Done?

FNAC may be recommended by your doctor at Orthomed Hospital Hisar for the following reasons:

• To evaluate a palpable lump in the neck, breast, thyroid, or any soft tissue 
• To assess enlarged lymph nodes 
• To investigate swellings of unknown cause 
• To determine whether a mass is benign or malignant before planning surgery 
• To diagnose infections, cysts, or abscesses 
• To monitor known tumours for changes

FNAC provides a diagnosis without the need for a surgical biopsy in many cases, making it an extremely valuable and cost-effective tool.

How Should You Prepare?

FNAC requires very little preparation:

• No fasting is necessary unless the test is combined with another procedure requiring anesthesia. 
• Inform your doctor about any blood-thinning medications you are taking (such as aspirin or warfarin)—these may need to be paused.
• Wear comfortable clothing that allows easy access to the area being tested 
• There is no need to arrange for someone to drive you home—the procedure is quick and you can leave on your own afterwards

For breast or thyroid FNAC, no special preparation is needed beyond what is listed above.

What Happens During the Procedure?

The procedure at Orthomed Hospital Hisar, is straightforward and takes only 5 to 15 minutes:

1. You will be positioned comfortably, sitting or lying down, depending on the location of the lump
2. The skin over the area is cleaned with an antiseptic 
3. A local anesthetic may or may not be used—many patients find the procedure causes only mild discomfort, similar to a routine blood test 
4. A thin needle (much finer than a standard injection needle) is inserted into the lump and a small sample of cells is withdrawn 
5. The needle is removed, and light pressure is applied to prevent bruising. 
6. The cell sample is prepared on a glass slide and sent to the pathology laboratory

For deeper lumps that are not easily felt, ultrasound guidance is used to direct the needle precisely.

Is the Procedure Painful?

Most patients describe FNAC as causing minimal discomfort, comparable to a routine blood draw. The needle used is very thin, and the procedure is completed quickly. You may feel mild soreness or bruising at the site for a day or two after the test, but this resolves on its own.

Understanding Your Results

FNAC results are typically available within 24 to 72 hours at Orthomed Hospital Hisar. Results are categorized as

• Benign: The cells are normal or non-cancerous. Further monitoring or treatment may be recommended depending on the cause. 
• Malignant: Cancerous cells are present. Your doctor will discuss the next steps, which may include imaging, a surgical biopsy for confirmation, or direct treatment planning. 
• Suspicious or indeterminate: The cells show some abnormal features, but a definitive diagnosis cannot be made. A surgical biopsy may be recommended for a more conclusive result. 
• Inadequate sample: Insufficient cells were collected for a reliable diagnosis. The test may need to be repeated.

FNAC results should always be interpreted in the context of your clinical history, physical examination, and imaging findings.
