Biopsiamenetelmiä

Biopsiamenetelmiä refer to various techniques used to obtain a tissue sample from the body for diagnostic purposes. These samples are then examined under a microscope or by other laboratory tests to identify abnormalities, such as cancer, inflammation, or infection. The choice of biopsy method depends on the location and size of the suspected abnormality, as well as the patient's overall health.

Common biopsy techniques include needle biopsies, surgical biopsies, and endoscopic biopsies. Needle biopsies involve using a hollow needle to extract a small sample of tissue. This can be done with a fine needle (fine-needle aspiration or FNA) or a larger, hollow needle (core needle biopsy). Surgical biopsies involve the removal of a larger piece of tissue, either by making a small incision (incisional biopsy) or by removing the entire suspicious area (excisional biopsy). Endoscopic biopsies are performed during an endoscopy, where a flexible tube with a camera and instruments is inserted into the body, allowing for the collection of tissue samples from internal organs.

Other specialized biopsy methods exist for specific organs or conditions, such as bone marrow biopsies, skin biopsies, and liquid biopsies. Liquid biopsies analyze biological fluids, like blood, for tumor DNA or cells. The procedure is generally safe, but potential risks include bleeding, infection, and pain at the biopsy site. The results of a biopsy are crucial for accurate diagnosis and guiding treatment decisions.
