FNAC Test in Chennai

What does the FNAC test mean?

FNAC test stands for Fine Needle Aspiration Cytology. It is a diagnostic technique that involves using a thin needle to extract a small sample of cells from a lump or abnormal area. These cells are then examined under a microscope by a pathologist to determine if they are benign (non-cancerous), malignant (cancerous), inflammatory, or infectious.

This test is widely used because it is simple, cost-effective, and provides rapid results, often avoiding the need for more invasive biopsies initially. It is commonly performed on:

• Thyroid nodules
• Breast lumps
• Enlarged lymph nodes
• Salivary gland swellings
• Soft tissue masses

What Is the FNAC procedure?

The FNAC procedure is straightforward and usually completed in an outpatient setting:

Preparation: The area is cleaned and sometimes numbed with a local anaesthetic spray or injection for comfort.

• Aspiration: A very fine needle (thinner than those used for blood tests) attached to a syringe is inserted into the lump. Gentle suction draws out cells or fluid.
• Sample Processing: The collected material is spread on glass slides, stained, and sent for microscopic analysis.
• Duration: The entire process typically takes 10-20 minutes.

No stitches are required, and most patients experience only mild discomfort, similar to a blood draw. Ultrasound guidance may be used for deeper or smaller lesions to improve accuracy.

Why Is This Test Important?

The FNAC test plays a crucial role in:

• Differentiating between benign and malignant lesions.
• Identifying infections or inflammatory conditions like tuberculosis.
• Guiding further management, such as surgery, medication, or monitoring.
• Reducing unnecessary operations by providing early information.
• Symptoms that may lead to this test include:
• Palpable lumps in the neck, breast, or armpits.
• Persistent swelling that does not resolve.
• Unexplained weight loss or fever with enlarged nodes.
• Changes in a known nodule or mass.
• Early evaluation through FNAC supports timely intervention and better outcomes.

Preparation and Risks

Preparation is minimal:

• Inform your doctor about blood-thinning medications or allergies.
• No fasting is usually needed.
• Risks are low and may include:
• Minor bleeding or bruising at the site.
• Slight soreness for a day or two.
• Rarely, infection (prevented with sterile technique).
• Most patients resume normal activities immediately after the procedure.

Interpreting Results

FNAC results are reported based on cellular appearance and are often categorised using systems like the Bethesda system (for thyroid) or similar classifications for other sites:

FNAC test positive means abnormal or malignant cells have been identified in the sample, suggesting the presence of cancer or significant pathology. This prompts further evaluation but is not always a final diagnosis—correlation with clinical findings and imaging is essential.
