The removal of cells or tissues for examination by a
pathologist. The pathologist may study the
tissue under a
microscope or perform other tests on the cells or tissue. There are many different types of
biopsy procedures. The most common types include: (1)
incisional biopsy, in which only a sample of tissue is removed; (2)
excisional biopsy, in which an entire lump or suspicious area is removed; and (3)
needle biopsy, in which a sample of tissue or
fluid is removed with a needle. When a wide needle is used, the procedure is called a
core biopsy. When a thin needle is used, the procedure is called a fine-needle
aspiration biopsy.
aspiration (AS-pih-RAY-shun)
Removal of fluid or tissue through a needle. Also, the accidental breathing in of food or fluid into the lungs.
