nõelbiopsiaga

Nõelbiopsia is a medical procedure used to obtain a small sample of tissue or cells from the body for examination. The term "nõelbiopsia" translates from Estonian to "needle biopsy." This minimally invasive technique is commonly employed for diagnostic purposes, helping physicians to identify the nature of suspicious lumps, lesions, or abnormalities detected through imaging tests or physical examination.

There are several types of needle biopsies, with fine-needle aspiration (FNA) and core needle biopsy being the most prevalent. FNA involves using a very thin needle to withdraw fluid and cells from a mass. A core needle biopsy, on the other hand, utilizes a larger, hollow needle to extract a small cylinder of tissue. The choice of technique depends on the size, location, and suspected characteristics of the tissue in question.

The procedure is typically performed under local anesthesia to minimize discomfort. After sterilizing the skin, the needle is inserted into the target area, and the sample is collected. The retrieved tissue or cells are then sent to a pathology laboratory for microscopic analysis by a pathologist. This analysis helps determine if the cells are cancerous, benign, or indicative of other diseases. Nõelbiopsia is a crucial tool in the diagnostic process, allowing for timely and accurate identification of various medical conditions.
