Mammo 8: Diagnosis and Early Detection Of Breast Cancer Flashcards
Removal of a small amount of tissue for
examination under a microscope
Biopsy
Breast cancer can be diagnosed with through multiple tests or imaging modality including:
- Mammogram
- Ultrasound
- MRI
- Biopsy
is usually performed under stereotactic or ultrasound guidance using an
automated needle or vacuum-assisted biopsy probe
Percutaneous biopsy
Uses penetrating sound waves that
do not affect or damage the tissue
and cannot be heard by humans
Ultrasound Sonography
• Superior in distinguish a solid
mass,(cancer) and a fluid filled
cyst,(benign)
• Differentiating cancer from benign
Ultrasound Sonography
• Used as a surveillance method
following a breast cancer diagnosis
and treatment
MRI
MRI require the intravenous injection of____ contrast agent
gadolinium
A test that removes tissue or fluid
from the suspicious area
Biopsy
is the only diagnostic
procedure that can definitely
determine if the suspicious area is
cancerous or malignant.
biopsy
Types of Biopsy
1.Fine-needle aspiration/ FNA / FNAB
2.Core-needle biopsy
3.Surgical biopsy
4.Image-guided biopsy
5.Sentinel lymph node biopsy
This procedure is usually performed in the ultrasound section because it is ultrasound-guided
Fin-Needle Aspiration (FNA)
is chosen when the lump is likely to be filled with fluid
Fin Needle Aspiration (FNA)
Performed if the lump persists
FINE- NEEDLE BIOPSY / FNABX
A procedure to a small amount of
suspicious tissue from the breast
with a larger “core” needle
CORE-NEEDLE BIOPSY
Yields larger tissue samples
CORE-NEEDLE BIOPSY
•A small cut will be made over the area
• Part or all of the mass will be
removed and examined under a
microscope
Surgical Biopsy
A biopsy marker is a small clip or
metal object that’s placed in the
breast during a biopsy to mark the
biopsy site
Biopsy Marker
• Most of the biopsy marker are made
up of:
⚬ Zr (Zirconium) = 40
⚬ Ti (titanium) = 22
•During this procedure, a needle is
guided to the location of the mass or
calcifications with the help of an
imaging technique, such as
mammography, ultrasound, or MRI.
• Stereotactic Biopsy
Image-guided Biopsy
When the cancer spread through the lymphatic system the lymphatic
node or group of nodes the cancer reaches first is called a
sentinel lymph node
• Procedure in which the sentinel lymph node is identified, removed and
examined to determine whether cancer cells are present
• Used in people who have already been diagnosed with cancer
Sentinel Lymph Node Biopsy
• signs and symptoms of cancer are reduced after the removal of the
tumor.
• can be partial or complete
Remission
• all signs and symptoms of cancer have disappeared
Complete remission
When breast cancer is surgically removed, a rim of normal tissue
surrounding the tumor is also removed .
⚬ This rim is called ___.
⚬____ helps show whether or notthe tumor was remov
margin
