Radio wave
signals, similar to those used in cell phones, are being used
to detect breast cancers that have been missed by mammography,
according to researchers at Northwest Community Hospital in Arlington
Heights, IL.
"Malignant
tumors have a greater content of water than surrounding breast
tissue," said Dr. Allan Malmed, director of breast care at
NCH and lead investigator of the study. The Breast Cancer Radar
(BCR) technology creates three-dimensional images that show the
size and location of cancers using this physical feature.
This radio
wave technology has been used to image 22 patients with known
breast cancer or breast cysts, accurately depicting the tumors
and cysts, according to Malmed.
Because BCR
technology is based on water content, breast density has no affect
on the quality of the image, said Malmed.
"Early
indications are that this test could be an adjunct to mammography.
This test may benefit patients with dense breasts as well as other
patients who have negative mammograms yet, for some reason, such
as a family history of breast cancer, we are concerned that the
additional tests are needed," said Malmed.
The BCR procedure
takes approximately five minutes and there is no compression of
the breasts. Images of both breasts are taken at the same time.
Clinical trials
are scheduled for summer 2002 comparing BCR in combination with
mammography to mammography alone.
