A biopsy is the removal of tissue in order to examine it for disease. The tissue samples can be taken from any part of the body.
Biopsies are performed in several different ways. Some biopsies involve removing a small amount of tissue with a needle while others involve surgically removing an entire lump, or nodule, that is suspicious.
Often, the tissue is removed by placing a needle through the skin to the area of abnormality. Biopsies can be safely performed with imaging guidance such as ultrasound, x-ray, or computed tomography (CT). These types of imaging are used to determine exactly where to place the needle and perform the biopsy.
