The number of women having breast cancer screenings on a regular
basis has declined in recent years, experts agree.
New technology may not be enough of an incentive to get women
back into the screening rooms. But the director of diagnostic
imaging for Lovelace Women's Hospital figures talking about digital
mammography just might help raise awareness.
"People think cancer of the breast is on a decline, but it's
not," says Barbara Becker, who oversees operation of the new
technology installed at the hospital a couple of months ago.
Becker says digital mammography, which replaces the traditional
analog system, makes mammograms more accurate for many patients, and
faster for almost all.
"We can get you in and out and on your way in 15 minutes," says
Becker. And, she says, the images are sharper, easier to read, take
less radiation, require little patient preparation and help reduce
inconvenience.
Computer image
Digital mammography, also called full-field digital mammography,
uses a process similar to digital photography that produces images
of the breast that can be seen on acomputer screen. Computer
software can then search the image for abnormal areas of density,
mass or calcification that may indicate the presence of cancer.
Becker says the digital images are clearer and easier to adjust
than the older film images. A radiologist has the ability to lighten
or darken the image, adjust its contrast and zoom in to study a
possible problem area.
Dr. Gary Wood, president and director of breast imaging for
Radiology Associates of Albuquerque, agrees that digital imaging is
more accurate for many women. He cites a study that found detection
rates had improved by as much as 28 percent for women with dense
breasts or who were premenopausal or perimenopausal.
Those statistics, combined with good business sense, were reasons
RAA was the first in Albuquerque to begin offering digital
mammograms nearly a year ago, says Wood. The business recently was
designated by the American College of Radiology as a Breast Imaging
Center of Excellence, the first and only facility in the state to
receive such recognition, Wood says.
"We did it because we thought it was the best thing to do for
patient care," the doctor says. "Digital is one more tool that
allows us to be state of the art."
Wood blames the national decline in mammograms on several
factors: decreased public attention to breast cancer awareness, a
drop in the number of people insured and insurance companies that
are now requiring deductibles for the screenings. He isn't convinced
that converting to digital technology will improve screening
compliance, but it might help get the discussion going again.
Becker and Wood agree there is a practical side to digital
mammography as well. The results are easier to store and access,
they say.
Half the time
The digital mammograms also allow for quicker exams, Becker says,
which can be beneficial for patients and facilities alike.
She says an analog mammogram took 30 to 40 minutes, most of that
time spent waiting to see if the image came out OK. Because digital
imaging is almost immediate, that time has been cut in half. That's
nice for patients; it's also good for places like the Lovelace
Women's Center, which can now book more than 1,000 mammograms a
month.
RAA schedules mammograms every 10 minutes. Wood says the facility
has done more than 42,000 mammograms since converting to digital.
Becker says the digital technology also allows physicians quicker
and easier access to screening results. With the appropriate
software, which Lovelace will provide for free, physicians can have
the results sent to them online and then review them at their
convenience in their offices. However, Wood warns that these doctors
should have high-resolution monitors and experience reading
mammograms.
Digital mammography is more expensive than its predecessor, and
the price patients are charged reflects the cost increase. Lovelace
increased its fee by about $12, to $200, to cover the expense,
Becker says, adding that annual screenings typically are covered by
insurance.
Because the technology is expensive, few facilities in the state
have made the transition to digital mammography. Wood says a digital
machine costs about $400,000, compared to $80,000 for the analog
machines. "You've got to be able to do high volume" to justify the
cost, he says.
He says women in areas that don't have access to digital
mammograms shouldn't lose faith in the older system. It's important
that women continue to get screened for breast cancer, Wood says,
recommending that women age 40 and older have a mammogram once a
year.
Breast cancer is still the second-leading cause of cancer death
for women, and statistics show that when it is discovered early,
there is a 95 percent cure rate, he says.
