FNAC is an abbreviation for Fine Needle Aspiration Cytology. FNAC is a diagnostic

procedure in which a needle is inserted on the raised part of the body to extract a small

amount of tissue to perform analysis under a microscope. Lumps on the neck, breast, or any

other part of the body that appear without a reason and do not recede even after a long time,

can be malignant. If you notice any bump on your body and could not fathom the reason for

the same, the doctor may prescribe you a FNAC test.
