needle aspiration
:
a type of needle biopsy. The removal of fluid from a cyst or cells from a tumor. In this procedure, a needle is used to reach the cyst or tumor, and, with suction, draw up (aspirate) samples for examination under a microscope. If the needle is thin, the procedure is called a fine needle aspiration or FNA. See also, biopsy.
needle biopsy
:
removal of fluid, cells, or tissue with a needle for examination under a microscope. There are two types: fine needle aspiration (also called FNA or needle aspiration) and core biopsy. FNA uses a thin needle and syringe (like those used to give injections) to pierce the skin and draw up (aspirate) fluid or small tissue fragments from a cyst or tumor. A core needle biopsy uses a thicker needle to remove a cylindrical sample of tissue from a tumor.
needle localization
:
a procedure used to guide a surgical breast biopsy when the lump is hard to locate or when there are areas that look suspicious on the x-ray but there is not a distinct lump. A thin needle is placed into the breast. X-rays are taken and used to guide the needle to the suspicious area. The surgeon then uses the path of the needle as a guide to locate the abnormal area to be removed. See also, wire localization.
