\f0\fs24 \cf0 >>> DR. JAY K. HARNESS: \f1 What is a sentinel lymph node biopsy?
Well, if you think of this a centaurian, a guard, the sentinel lymph nodes are the lymph
nodes nearest to where a tumor is. Sentinel lymph nodes can be on the lymph nodes in the
axilla, in the breast, or some other locations near the breast, but they can also be the
lymph nodes in the head and neck area that might be draining a thyroid cancer, or a colon
cancer, or whatever. \ \pard\tx2367\pardeftab720\ri720\qj
\cf0 \ The concept here is that if cancer cells are
going to metastasize and grow in lymph nodes, the theory is that they will go to the initial
lymph nodes draining that area. Those are called the sentinel lymph nodes. How do we
identify the sentinel lymph nodes in breast cancer? Two ways: One is we inject a radioactive
isotope into the breast and that those particles migrate down to the sentinel lymph node, or
nodes, and sit there, and we can then find them with a little Geiger counter; and/or
we can inject blue dye which will again go down the lymphatic channels and sit in the
lymph nodes. \ \
So those are the two typical ways that we use to identify sentinel lymph nodes. We particularly
use this technique with invasive cancers, but there are certain high-grade in situ breast
cancers where we may also wish to check the sentinel lymph nodes. \
\ Hi, I am Dr. Jay Harness and I want to share
with you important information that I believe that every newly diagnosed patient with breast
cancer needs to know. \ \
I am a breast cancer survivor. \ \
I am a breast cancer survivor. \ \
I am a breast cancer survivor and I want every woman to know about personal life, breast
cancer treatment and the genomic test \'96 a test that helps guide a woman and her doctor
to the best treatment options for her. \ \
Pass it on! \ }
