Infrared
Mammography and Early
Detection
The
goal of breast cancer screening is early detection. Most
women are surprised to learn that it takes about 8 years for a
breast cancer to grow from a single abnormal cell to a
mass that is regularly detected by x-ray
mammography. More aggressive cancers grow faster and
less aggresive cancers grow slower, but 8 years is about the
average. At that point its a tumor approximately 10
millimeters or more in size.
How do we know
this? The largest study to ever
estimate accuracy and size determined
that x-ray mammography finds 91% of cancers 10 millimeters in
size, but only detects 26% of cancers 5 millimeters
in size. Breast cancers detected by x-ray
mammography are typically about 12-16 millimeters in size
and only about a 1-2 years away from
being detected by a clinical breast exam, self breast exam or as a woman becomes
symptomatic.
Poor detection below 10
millimeters in size is the biggest limitation of
x-ray mammography. And while x-ray mammography has come
a long way in reducing the radiation dose and in going
digital, these improvements have not improved the detection
rate of breast cancer for most women.
Infrared Mammography works differently. It screens for breast cancer by
detecting small temperature changes in a woman's breast that are
associated with breast cancer. So instead of directly looking for a mass, infrared
mammography looks for temperature changes caused by breast cancer
and other breast diseases
associated with breast cancer. For most women, this means screening
positive earlier. Decades of research has concluded that women can screen positive by
infrared mammography up to 7 years earlier than by x-ray mammography.
Infrared mammography gives
most women greater peace of mind because of its ability to
screen for breast cancer in the earliest stages. For a
woman who are at high risk of having or
developing breast cancer, it can provide an early warning
to screen regularly, monitor changes in the breast, and
to make positive changes in her life.
The results from
infrared mammography should be considered by your physician
when determining an appropriate x-ray mammography screening
schedule. Women who have been shown to be at low risk by
both infrared mammography and x-ray mammography should consult
with their physician to determine if they can reduce the
number of x-ray mammograms they receive.
Conversely, women who screen positive by infrared
mammography but negative by x-ray mammography should make sure
they are screening regularly. Even with a
negative x-ray, an abnormal infrared image is the single most
important marker of high risk for developing breast cancer,
and is 10x more of a risk factor than having an
immediate family member with breast
cancer.
