You
will be offered several options for diagnosis and
treatment of your breast problem. The options will
be given to you, recommendations will be made and
you will be able to decide what works best for
you.
BIOPSY:
LEARNING IF YOU HAVE BREAST CANCER
If
you have noticed a lump or other change in your breast,
your doctor may recommend several tests to determine
if you indeed have cancer. After taking your medical
history and performing a manual breast exam, your
doctor may recommend a breast x-ray or mammogram,
ultrasound, and/ or MRI. You may be asked to have
a combination of these tests. If the lump is suspected
to be a cyst, your doctor may use a needle to drain
fluid from the lump.
Another
test is a biopsy where tissue is removed and
a pathologist examines it under a microscope. The
mass or a portion of it is removed under local or
monitored anesthesia. Biopsy is the only certain
way to diagnose breast cancer. Minimally invasive
core biopsies using mammography and ultrasound
to guide the procedure have become the standard of
care when it is technically feasible. Complete
surgical excisionbiopsy may be recommended
if the mass is located in a part of the breast that
makes this the best option for diagnosis.
During
the biopsy procedure, the surgeon removes the suspicious
tissue to see if it is benign or malignant. If it
is malignant, the pathologist will try to identify
the type of cancer cells present, how fast they reproduce,
if the blood vessels or lymph systems contain cancer
cells, and if the cancer’s growth is affected
by hormones. This information allows your doctor
to determine the best treatment for you.
There
are two ways that a pathologist prepares the tissue
for examination – a “frozen section,” which
is a quick procedure that takes about 30 minutes,
and a “permanent section,” which
takes two to three days.
The
frozen section is a quick way of determining whether
or not cancer is present in the tissue. The permanent
section is the most accurate method.
Mammotome -
A breast biopsy device that can sample specific areas
of concern on your mammogram, your ultrasound or
on your clinical exam.
MRI Guided Biopsy -
When an abnormality is identified on MRI and it is the only modality that identified the lesion, a biopsy may require MRI guidance. Your biopsy will be performed in the Aurora dedicated breast MRI scanner.
After an initial scan, an injection of gadolinium will allow our radiologist and surgeon to identify the abnormality; sophisticiated software is then used to localize the lesion. Once the lesion is localized, you will have your breast cleansed, after which local anesthesia is administered. The biopsy device is placed, and an additional scan confirms that we are in the appropriate position. When the position is confirmed, the biopsy is performed, and a marker is placed to identify the biopsy site in the event that a cancer or atypical lesion is found. The final scan confirms the placement of the marker, and steri-strips are placed, as is an ace wrap, which helps prevent bleeding.
Stereotactic
Breast Biopsy - With this type of biopsy,
the mammogram is used as our guide to obtain the
specific tissue that we need to sample.
You
are placed face down on the table and your breast
hangs through a hole in the table. The breast is
then imaged with a low dose mammogram to find the
density or area of calcifications. Once the area
is identified, the computer helps to determine the
appropriate placement of the mammotome? device. Once
images are confirmed, the breast is cleansed and
anesthetized with local anesthesia. After a tiny
nick is made in the skin, the device is positioned
and checked. The area is further infiltrated with
Lidocaine to numb or deaden the area. The samples
are then taken and an x-ray confirms the presence
of the calcifications in the specimens. At the completion
of the procedure, a radiologic marker is placed to
mark the area for future reference. The marker may
be made of titanium or surgical steel. Don’t
worry; they will not set off the metal detectors
in the airport!
This
marker allows us to know where to return to if further
surgery is needed, and it also allows the radiologist
in the future know that you did indeed have a biopsy
of that area. When the procedure is completed, the
technologist will initially hold pressure on the
area and they apply steri-strips or surgical glue.
An outer dressing is placed. You may have a regular
mammogram immediately after the procedure if one
is necessary to confirm that the appropriate area
has been biopsied.

Hand
Held Mammotome - Biopsy with Ultrasound
Guidance-This
procedure is performed when there is either an
ultrasound abnormality or a palpable mass in the
breast. The patient is placed in the supine position
and her arm is usually over her head.
Once
the breast is scanned with the ultrasound machine,
the area for biopsy is marked with a surgical marker.
The breast is then cleansed with betadine and anesthetized
with Lidocaine. The incision is made as a tiny nick
in the skin. A larger needle is then used to assure
the area is completely numb. Once the Lidocaine is
allowed to work, the mammotome is inserted under
ultrasound guidance.
Once
position is checked, the area is sampled. If all
image evidence of the lesion is to be removed, the
procedure is continued until the ultrasound image
of the density confirms the removal. A tiny marker
is then placed for future reference. Pressure is
held over the biopsy cavity and then steri-strips
and sterile dressings are placed. A mammogram may
be performed if confirmation of a Mammographic lesion
is necessary.

Core
Needle Biopsy - A biopsy performed in
the doctor’s office to make a diagnosis of
a breast problem. When the patient and the doctor
feel a lesion, a core biopsy can be used to confirm
a diagnosis and/or to rule out a cancer. The procedure
involves the cleansing and numbing of the skin.
A
small nick is then made in the skin and the core
needle device is repeatedly placed in the breast
fired and removed, until adequate samples are obtained.
With this biopsy technique the area is not removed,
just sampled. No sutures are needed, just steri-strips
to approximate the skin.
Fine
Needle Aspiration - A procedure that is
performed to sample cells from a solid lesion or
to confirm that a mass is a fluid filled cyst.
A skinny needle is inserted into the breast without
anesthesia. This may be done with or with out ultrasound
guidance.
If
fluid is obtained, it may be discarded or tested
based upon its consistency.
Further biopsies may be required if the mass is solid.
Open
Surgical Biopsy - A procedure performed
in the operating room that will remove a palpable
mass. It is always an option when you can feel
the lesion. It is at times the recommended procedure
if the mass is near the nipple or very close to
the surface of the skin.
Risks
Bleeding
Infection
Anesthesia

Needle
Localization Biopsy - An open biopsy that
uses the placement of a needle to guide the surgeon
to the area of interest. It is placed under Mammographic
guidance or ultrasound guidance. It may be used
as a primary procedure or as a follow up to a Stereotactic
or mammotome biopsy.
Risks

The frozen
section is performed while the patient is in
the operating room. A frozen section is requested
and performed if it will change the intraoperative
management of your breast disease.
Many
lesions, which are small or are found by needle localization,
are often best served by the permanent section. The
purpose is to obtain a correct final answer and avoid
a quick, potentially inaccurate, answer.
The permanent
section takes longer than a frozen section – usually
two or three days. In this permanent section process,
the tissue is treated by a series of chemical solutions
that give a high quality slide. The advantage of
this process is that it is more accurate and allows
the pathologist to make a more correct diagnosis.
Permanent sections are always done, even if the
frozen section was previously performed.
If
your lump is cancerous, estrogen and progesterone
receptor assay tests will be performed as well as
testing for Her-2-neu expression. These tests will
determine whether treatment with anti-estrogen agents
may benefit you. The cancer is also graded on a microscopic
level (Grade I, II, III) to give your physicians
an estimate of the aggressiveness of the tumor.
