Biopsies
Biopsies
Biopsies (/ˈbaɪɒpsi/; singular: biopsy) are medical tests involving extraction of sample cells or tissues for examination to determine the presence or extent of a disease. The etymology of the word biopsy comes from the Greek words "bios" (life) and "opsis" (sight).
Types of Biopsies
There are several types of biopsies, including:
- Excisional Biopsy: The removal of an entire lump or suspicious area.
- Incisional Biopsy: The removal of a portion of a lump or suspicious area.
- Core Needle Biopsy: The use of a large needle to remove a sample of tissue.
- Fine Needle Aspiration Biopsy: The use of a thin needle to remove cells or fluid.
- Skin Biopsy: The removal of cells from the surface of the body.
- Bone Marrow Biopsy: The removal of a sample of bone marrow.
Procedure
The procedure for a biopsy typically involves the use of a needle or surgical procedure to remove a small sample of tissue, which is then examined under a microscope by a Pathologist. The pathologist will look for abnormal cells and may perform additional tests to determine the type and stage of disease.
Risks and Complications
While biopsies are generally safe, they do carry some risks, including infection, bleeding, and damage to surrounding tissues. The specific risks can vary depending on the type of biopsy and the area of the body being tested.
