Fna what does it stand for

Because an FNA biopsy can only sample a small number of cells from a mass or lump, there is a risk that any abnormal cells may be missed and not detected.

This may mean that a larger sample must be taken, for example by core needle biopsy. It is sometimes used instead of fine needle aspiration biopsy, or vice versa. Core biopsy is a more invasive procedure than FNA, as it involves making a small incision cut in the skin. A large needle is then passed through this incision and several narrow samples of the tissue to be investigated such as a lump are taken.

As with fine needle aspiration, ultrasound or mammographic guidance may be needed to locate the lump or area to be sampled. Core biopsy is done under local anaesthetic. The procedure usually takes between 30 minutes and 1 hour. After the procedure, the biopsy area will be covered with a simple dressing. A core biopsy may result in a small, very fine scar where the incision was made. The samples of tissue taken during a core biopsy differ from those taken during FNA.

Because the cells from a fine needle aspiration biopsy are sucked up randomly into the needle, they are seen under the microscope as a disorganised jumble of cells see the image at right. With a core biopsy sample, however, the larger needle allows the cells to be removed with their relationship to each other intact. This can sometimes help in diagnosis.

Some cells appear abnormal but are not definitely cancerous. A surgical biopsy may be required to adequately sample the cells. Malignant: The cells are cancerous, uncontrolled and have the potential or have spread to other areas of the body. Effectiveiness of a Fine Needle Aspiration Biopsy A fine needle biopsy is an effective tool in evaluating and diagnosing suspect lumps or masses. Benefits and Risks of a Fine Needle Aspiration Biopsy A fine needle biopsy is a quick and effective test for determining the status of suspect tissue.
