With the new ultra-sensitive, high resolution
digital infrared cameras available today a
technology that has been developing over the
past 20 years is now becoming more accessible.
Thermography as a physiologic test, demonstrates
heat patterns that are strongly indicative of
breast abnormality, the test can detect subtle
changes in breast temperature that indicate a
variety of breast diseases and abnormalities and
once abnormal heat patterns are detected in the
breast, follow-up procedures including
mammography are necessary to rule out or
properly diagnose cancer and a host of other
breast diseases such as fibrocystic syndrome,
Pagets disease, etc.
Canadian researchers recently found that
infrared imaging of breast cancers could detect
minute temperature variations related to blood
flow and demonstrate abnormal patterns
associated with the progression of tumours.
These images or thermograms of the breast were
positive for 83% of breast cancers compared to
61% for clinical breast examination alone and
84% for mammography.
By performing thermography years before
conventional mammography, a selected client
population at risk can be monitored more
carefully, and then by accurately utilize
mammography or ultrasound as soon as is possible
to detect the actual lesion - (once it has grown
large enough and dense enough to be seen on
mammographic film), can increase the clients
treatment options and ultimately improve the
outcome.
It is in this role that thermography provides
its most practical benefit to the general public
and to the medical profession. It is certainly
an adjunct to the appropriate usage of
mammography and not a competitor. In fact,
thermography has the ability to identify clients
at the highest risk and actually increase the
effective usage of mammographic imaging
procedures.
Until such time as a cure has been found for
this terrible disease, progress must be made in
the fields of early detection and risk
evaluation coupled with sound clinical decision
making.
Thermography, with its non-radiation,
non-contact and low-cost basis has been clearly
demonstrated to be a valuable and safe early
risk marker of breast pathology, and an
excellent case management tool for the ongoing
monitoring and treatment of breast disease when
used under carefully controlled clinical
protocols.
