neulanäytteenotolla

Neulanäytteenotto, often referred to as needle aspiration or needle biopsy, is a medical procedure used to obtain a sample of tissue or fluid from a suspicious lump, mass, or organ within the body. This procedure is typically performed using a hollow needle inserted into the abnormal area. The primary purpose of neulanäytteenotto is diagnostic, aiming to determine the nature of the abnormality, such as whether it is benign (non-cancerous) or malignant (cancerous).

There are several types of neulanäytteenotto, including fine-needle aspiration (FNA) and core needle biopsy. FNA uses a very thin needle to extract cells, while a core needle biopsy uses a larger, hollow needle to remove a small cylinder of tissue. The choice of method depends on the size and location of the lesion and the type of information required. Imaging guidance, such as ultrasound or CT scans, is frequently used to ensure accurate needle placement.

The procedure itself is generally quick and can often be done on an outpatient basis. After the needle is inserted and the sample is collected, it is sent to a laboratory for examination by a pathologist. The pathologist analyzes the cells or tissue under a microscope to identify any abnormalities. The results of the neulanäytteenotto help guide further treatment decisions. While generally safe, potential risks include minor bleeding, bruising, infection, or pain at the needle insertion site.
