Stereotactic
Biopsy
What
Is Sterotactic Breast Biopsy?
This
simple procedure uses advanced computer imaging technology.
It allows for the removal of tiny sections of tissue that indicate
they required further attention after showing up on a mammogram
but cannot be felt. The ease and safety of this procedure,
typically performed during a brief office visit, is
well-documented.
This
modern procedure provides the same reliability as more complicated
surgical biopsy, but provides these significant advantages:
-
It
does not require anesthesia
-
It
requires less time
-
It
is more cost effective
-
It
is much less complicated
What
Will The Procedure Be Like?
The
Stereotactic Biopsy of a small area of your breast tissue will be
performed by Dr. Vopal.
Before
the procedure begins, you will need to remove the clothing from
the upper portion of your body and put on a gown. Dr. Vopal will position you as comfortably as possible on your
abdomen on a special X-ray table or seat you upright in a special
chair. If laying down, your breast will be gently
placed through an opening in the table, or if upright, onto the
same type of tray used for your mammogram. Once you are in
position, your breast will be held in place with light
compression. You will then be asked to hold your breath as
X-ray pictures are taken. This is done to verify the location
of the area to be sampled. If not quite right, you will be
repositioned until it is.
Dr.
Vopal will review these films. He will use a computer to
read the X-rays and locate the precise area of your breast tissue
which will be sampled.
Next,
Dr. Vopal will numb the area to be tested.
You may feel a tiny pinch similar to a pin prick. A small
incision (no more than 1/4") will be made through which the
biopsy needle will be inserted. You may feel some slight
pressure during this time. It is important to relax.
This is rarely painful.
Ultrasound
Guided Biopsy
Ultrasound
is an excellent way to evaluate breast abnormalities detected by
mammography, the patient or Dr. Vopal, but in some cases it is
not possible to tell from the imaging studies alone whether a
growth is benign or cancerous. Ultrasound-guided breast biopsy is
a highly accurate way to evaluate suspicious masses within the
breast that are visible on ultrasound, whether or not they can be
felt on breast self-examination or clinical examination. The
procedure prevents the need to remove tissue surgically, and also
eliminates the radiation exposure that comes from using x-rays to
locate a mass. After placing an ultrasound probe over the site of
the breast lump and using local anesthesia, the Dr. Vopal guides
a biopsy needle directly into the mass. Tissue specimens are then
taken using either an automatic spring-loaded or vaccum assisted
device (VAD).
Vacuum
Assisted Biopsy
The
relatively new vacuum-assisted breast biopsy is a percutaneous
("through the skin") procedure that relies on
stereotactic mammography or ultrasound imaging. Stereotactic
mammography involves using computers to pinpoint the exact
location of a breast mass based on mammograms (x-rays) taken from
two different angles. The computer coordinates help Dr. Vopal guide the needle to the correct area in the breast.
With ultrasound, Dr. Vopal will watch the needle
on the ultrasound monitor to help guide it to the area of concern.
The patient will either by positioned in the upright or prone
(face down) position for a vacuum-assisted biopsy.
Vacuum-assisted
biopsy is a minimally invasive procedure that allows for the
removal of multiple tissue samples. However, unlike core needle
biopsy, which involves several separate needle insertions to
acquire multiple samples, the special biopsy probe used during
vacuum-assisted biopsy is inserted only once into the breast
through a small skin nick made in the skin of the patient's
breast.
Ductal
Lavage
What
Is Ductal Lavage
Physicians estimate that over 95% of breast cancers begin in the
cells lining the breast ducts. It can take up to eight to 10 years
before these cells grow into a tumor large enough to be detected
by mammography (approximately one centimeter in diameter) or felt
during a physical breast exam. The term "lavage" is
French and means "wash" or "rinse." Ductal
lavage involves analyzing cells washed out from the breast ducts
to determine whether they have malignant qualities before they
develop into breast cancer.
Ductal
lavage is a minimally invasive procedure that involves collecting
samples of breast ducts cells and then examining the cells under a
microscope to determine whether they are normal, atypical,
suspicious, or malignant. The idea of testing fluid from the
nipple was first suggested in the 1950s by Dr. Papanicolaou, the
physician who developed the Pap smear to test for cervical cancer.
How
is Ductal Lavage Performed?
Most women who undergo ductal lavage experience little to no
discomfort during the procedure. To perform ductal lavage, Dr.
Vopal will apply a small amount of anesthetic cream to the
nipple area. A breast pump (or aspirator) is then used to apply
mild suction to the nipple to draw out tiny amounts of nipple
fluid from the milk ducts up to the nipple surface. Typically,
fluid will only be extracted from one or two breast ducts (each
breast contains six to eight ducts). These ducts are most likely to contain abnormal cells. Once these ducts
have been identified, an anesthetic is infused into the duct and a
catheter is threaded into the duct opening in the nipple for a
small distance. Next, salt water is sent through the catheter into
the breast duct to "wash" the duct and collect cells.
The breast cells that are washed out are sent to the pathology
laboratory for analysis.
