What is Thermography?
Thermography
measures the infrared radiation
(heat) which is constantly radiating
(emitting) away from the surface of
the human skin. Skin as an organ
breathes, exchanges gases with the
environment, cools us as well as
keeps us warm by letting heat out or
keeping it in by controlling the
amount of circulation, or blood
flow, in the skin. This automatic
regulation is done without conscious
thought and is controlled by the
autonomic nervous system via the
sympathetics. The whole process is
called thermoregulation.
The procedure is based on the
principle that chemical and blood
vessel activity in both
pre-cancerous tissue and the area
surrounding a developing breast
cancer is almost always higher than
in the normal breast. Since
pre-cancerous and cancerous masses
are highly metabolic tissues, they
need an abundant supply of nutrients
to maintain their growth. In order
to do this they increase circulation
to their cells by sending out
chemicals to keep existing blood
vessels open, recruit dormant
vessels, and create new ones
(neo-angiogenesis). This process
results in an increase in regional
surface temperatures of the breast.
Abnormal thermographic scans of the
breast clearly demonstrate abnormal
areas of heat. This gives the
clinician an alert that something
might be wrong with physiology of
the breast. It could be an
infection, inflammatory disease,
trauma or cancer.
Thermography uses no painful breast
compression, no radiation and is
non-invasive. It is an ideal tool
for mass screening not only for
women over 40, but younger women as
well. In our clinic, we have found
breast pathologies in women as young
as 18 utilizing thermal imaging
equipment. To deny the efficacy and
of thermal imaging of the breast as
an adjunctive diagnostic procedure
in the overall management of the
patient is a grave error.
The procedure is both comfortable
and safe using no radiation or
compression. By carefully examining
changes in the temperature and blood
vessels of the breasts, signs of
possible cancer or pre-cancerous
cell growth may be detected up to 10
years prior to being discovered
using any other procedure. This
provides for the earliest possible
detection of cancer. Because of
breast thermography's extreme
sensitivity, these temperature
variations and vascular changes may
be among the earliest signs of
breast cancer and/or a pre-cancerous
state of the breast.
Breast thermography has been
researched for over 30 years, and
over 800 peer-reviewed breast
thermography studies exist in the
index-medicus.
In this data base well over
250,000
women have been included as study
participants. Some of these studies
have followed patients up to 12
years. Breast thermography has an
average sensitivity and specificity
of
90%.
Studies show that:
-
An abnormal
infrared image is the
single-most important marker of
high risk for developing breast
cancer.
-
A persistent
abnormal thermogram carries with
it a 22 times higher risk of
future breast cancer.
-
When
thermography is added to a
woman's regular breast health
checkup, a
61%
increase in survival rate
has been realized.
-
Finally,
when used as part of a
multimodal approach (clinical
examination + mammography +
thermography),
95% of
early-stage cancers will be
detected.
