Fine Needle Aspiration
Fine needle aspiration is a type of biopsy procedure used for lung cancer or mesothelioma patients. In fine needle aspiration, a thin needle is inserted into an area of abnormal-appearing tissue or body fluid. As with other types of biopsies, the sample collected during fine needle aspiration can help make a diagnosis or rule out conditions such as cancer.
The use of a thin needle to withdraw material from the body for analysis. For example, when a nodule is felt in the thyroid, fine needle aspiration may be done to remove a tissue sample that can be examined to determine whether the nodule is benign or malignant. The aspirated material is examined under the microscope by a pathologist.
There is really not one particular type preparation before undergoing a fine needle aspiration procedure. You should be aware that your doctor may ask you to stop taking any blood-thinners or aspirin.
As far as eating goes, you will be asked to not consume and solid or liquid food for a few hours before the procedure. If your doctor tells you that you will be under sedation for the test, make sure you have arranged for someone to take you home.
