A Hairy Problem: An Australian firm plans to launch a
competitor to X-ray mammography. The technique
finds marks of breast cancer in the X-ray
diffraction pattern of a woman’s hair.

Fermiscan Holdings, a start-up firm in Sydney,
Australia, says it plans to commercialize a
controversial breast-cancer-screening technology that
most scientists have given up on. The technology would
replace traditional X‑ray mammography with a test
requiring just a hair sample—and access to a
multimillion-dollar particle accelerator called a
synchrotron. Fermiscan is betting that women will
greatly prefer offering a hair sample to suffering the
discomfort of mammography. Having analyzed 800 hair
samples collected from women as they go in for routine
breast exams, Fermiscan says it will be ready to start
offering screenings by the end of 2008. The trouble is,
eight years after the technique was first reported, no
independent laboratory has ever been able to make it
work.
Fermiscan’s test is based on technology licensed from
Veronica James, a physics professor at the Australian
National University in Canberra, who reported in 1999
that she could detect an abnormality in the hair of
women with breast cancer. In her research, James shot a
concentrated beam of X‑rays at single strands of hair.
When the beam hit the hair, the diffracted X‑rays formed
a pattern on the detector related to the molecular
structure of keratin, a protein found in hair. James
claimed to find a diffuse additional ring in the
diffraction pattern from hair samples of women with
breast cancer.

After she published her results, many women were eager
to ditch the discomfort of their yearly mammograms.
“All the women who were at our breast-cancer clinic were
saying: ‘Don’t give me any of these tests. Here’s some
of my hair,’ ” says Keith Rogers, a medical-imaging
expert and professor of materials science at Cranfield
University, in Swindon, England. He was one of the first
to try to reproduce James’s work. When Rogers failed to
find the same diffraction pattern, James publicly
rejected his results, claiming that Rogers had not
properly followed her methodology. James, who formerly
consulted for Fermiscan, declined to comment for this
article.
At least seven research groups, including one with
which James briefly collaborated, have now tried and
failed to reproduce her results. “Some very eminent
people have tried to reproduce it,” says Rogers. “The
irritating thing is I so much want to believe her, but
I can’t find the proper evidence.”
Halfway through its recent trial, Fermiscan claimed
that hair analysis has an 82 percent probability of
detecting breast cancer in a person who has the disease,
nearly matching the best results from mammography
trials. However, hair analysis has only a 77 percent
chance of correctly confirming that people without the
disease really don’t have it, making the test less
reliable than some mammography trials.
“It would be bloody wonderful if it worked”

If it succeeds, Fermiscan could wedge itself into a
lucrative market. About 1 million mammograms were
conducted in 2007 in the United States alone, according
to the U.S. Food and Drug Administration. Companies such
as GE, Hologic, and Siemens are encouraging clinics to
upgrade and purchase digital and three-dimensional
X‑ray mammography machines at a cost of hundreds of
thousands of dollars per unit.
The Fermiscan test will cost the consumer about
US $200 per sample, says David Young, Fermiscan’s
managing director. That’s more than the $50 to $150 it
costs for a mammogram in the United States, but with
Fermiscan the clinic wouldn’t need to purchase and
maintain its own imager. The Fermiscan test should take
just 24 hours to complete, including the time it takes
to ship the hair to the Advanced Photon Source at
Argonne National Laboratory, in Illinois, where
Fermiscan has its tests done. Young says that the
company will first market its services in Southeast
Asia, through a joint venture with regional health-care
provider Avia Reed International, in Singapore.
Although most scientists in the field have given up on
the technique, some remain hopeful that it will work.
“I wish [them] really well because it would be bloody
wonderful if it worked,” says Rogers.
