Types of Breast Biopsy
The size and location of the lump can determine which breast biopsy can be performed on the patient. Breast biopsy has several types to detect a suspicious lump, including:
Fine Needle Aspiration Biopsy (FNAB)
The use of a thin needle and syringe to collect and withdraw (aspirate) cells from a suspicious lump is known as a fine needle aspiration biopsy (FNAB). An FNAB is applied to identify cysts and other sample cells. The physician (a pathologist or surgeon) uses a thinner needle than needle used for blood test. The tissue will be examined under a microscope. Local anesthetic may or may not be applied because getting the anesthetic might hurt more than the biopsy due to a thin needle.
Stereotactic Core Needle Biopsy
The Stereotactic Core Needle Biopsy applies a combination of computer and x-ray device to evaluate any abnormalities. The location of the exact area of suspected cyst is displayed on the computer screen. The biopsy is applied to locate microcalcifications or calcium deposits.
Vacuum-assisted Core Biopsy
A procedure in which a small sample of tissue is taken from the breast. A hollow probe is inserted through an incision made in numbed skin on the breast. The sample will be obtained through a small rotating knife in the probe. The VACB needs no stitches.
Magnetic Resonance Imaging (MRI)
The Magnetic Resonance Imaging might lead the biopsy to help discover the tumor and lead the biopsy instrument to the tumor. A computer analysis helps an MRI perform this biopsy.
