FNAC, or Fine Needle Aspiration Cytology, is a simple test that helps doctors find out what is inside a lump or swelling. In radiology, FNAC is important because it gives quick answers about many health problems. This blog will explain what FNAC is, when it is used, how it works, and what you can expect from the procedure.
What is FNAC?
FNAC stands for Fine Needle Aspiration Cytology. It is a test where a thin needle is used to take a small sample of cells from a lump or swelling. Doctors often use FNAC to check for infections, cysts, or cancer. Because the needle is very fine, the procedure is usually quick and causes little pain. FNAC is a common tool in radiology and pathology.
When is FNAC Recommended?
Doctors may suggest FNAC for several reasons. For example, if you have a lump in your neck, breast, thyroid, or other body parts, FNAC can help find out what it is. Sometimes, FNAC is used to check lymph nodes or other swellings. In many cases, FNAC helps avoid surgery by giving fast results.Unexplained lumps or swellingsThyroid nodulesBreast lumpsLymph node enlargementSalivary gland swellings
Often, FNAC is the first step before other tests or treatments.
How is FNAC Performed?
First, the doctor cleans the skin over the lump. Next, a thin needle is gently inserted into the lump. The doctor moves the needle to collect a small sample of cells. Sometimes, an ultrasound helps guide the needle to the right spot. After that, the sample is sent to a lab for study. Usually, the whole fine needle aspiration cytology procedure takes less than 30 minutes.Skin is cleanedNeedle is insertedCells are collectedSample is sent to the lab

Preparing for an FNAC Procedure
Usually, you do not need special preparation for FNAC. However, your doctor may ask about any medicines you take, especially blood thinners. It is important to tell your doctor if you have allergies or bleeding problems. In most cases, you can eat and drink as usual before the test. If you have questions, ask your healthcare provider before the procedure.
What to Expect After FNAC
After FNAC, you can usually go home right away. Sometimes, there may be mild pain or bruising where the needle was inserted. Placing a small bandage over the area can help.
