finnålsaspiration
Finnålsaspiration, often abbreviated as FNA, is a medical diagnostic technique used to obtain a sample of cells or fluid from a suspicious lump, mass, or organ. The procedure involves inserting a very thin, hollow needle, typically attached to a syringe, into the target area. The needle is then used to gently aspirate, or withdraw, a small amount of tissue or fluid. This sample is subsequently sent to a laboratory for examination under a microscope by a pathologist. Finnålsaspiration is a minimally invasive procedure, generally well-tolerated by patients, and can often be performed in an outpatient setting. It is commonly used to evaluate abnormalities in various parts of the body, including the thyroid, breast, lymph nodes, and salivary glands. The primary purpose of FNA is to determine whether the sampled cells are benign (non-cancerous) or malignant (cancerous), or to identify the cause of fluid accumulation. The results of an FNA biopsy can guide further treatment decisions. While generally safe, potential risks include minor bleeding, bruising, or infection at the needle insertion site. In some cases, the sample obtained may be insufficient for diagnosis, requiring the procedure to be repeated.
