Fine Needle Aspiration Biopsy
Fine needle aspiration uses a needle to remove tissue or fluid from a
lump or cyst in the breast. The sample is then analyzed under a
microscope to check for signs of disease.
Simple aspirations attempt to draw fluid from lumps that may be cysts
using a small gauge needle. Fine needle biopsy uses a larger needle to
make multiple passes through a lump, drawing out tissue and fluid. This
screening test does not require any incisions.
Stereotactic and Core Biopsies
A stereotactic breast biopsy identifies the location of an abnormal
area in three dimensions using a special mammography machine. The 3D
image helps guide a radiologist when collecting a tissue sample for a
core biopsy. This technique provides an alternative to surgical methods
for diagnosing a breast condition.
Tumor localizations mark the surgical site for a breast surgeon. With
the guidance of mammography or ultrasound, the breast area is numbered.
Then, a thin wire is inserted into the breast and blue dye is injected.
When the patient goes to surgery, the markings provide a guided map for
the breast surgeon to remove tissue.
Ultrasound Core Biopsies
Your doctor may recommend an image-guided biopsy if you have an
abnormal area in the breast that is difficult to locate by feel. With
ultrasound core biopsies, a radiologist uses ultrasound techniques to
find the suspicious area. Then, a needle is inserted into the mass so
tissue can be removed and examined for the presence of cancer cells.
