Painless, 3-D Mammograms
Reported March 2, 2007
(DURHAM, N.C. (Ivanhoe Broadcast News) -- Breast cancer ... 180,000
women will be diagnosed with it this year. One in four will die. Detecting
it as early as possible is crucial for survival, and now doctors are working
on a new tool to track the tiniest tumors.
Scrapbooker Jennifer Graham is cutting, pasting and keeping track of her
journey through cancer -- a journey she thought she would never take.
"[I thought] 'This can't be happening to me,'" Graham says. "I'm too young
for this." Like most women in their 30s, she never even had a mammogram. "I
did a self breast exam, and I felt a lump."
Researchers at Duke University Medical Center in Durham, N.C., are working
on ways to detect cancer in younger women and find smaller tumors than ever
before.
Painless, 3-D Mammograms"The idea is that being able to catch the cancer
earlier, you'll be able to do something to potentially cure these women
earlier," Martin Tornai, Ph.D., a radiologist at Duke University Medical
Center, tells Ivanhoe.
Graham has created a new type of CT scanner that provides a 3-D image of the
breast. Traditional mammograms provide only a 2-D image and can be painful
-- compressing the breast and distorting the image.
Dr. Tornai says, "Our first priority is to make sure that patients are going
to be comfortable because mammography often turns off a group of women from
actually going to get regular screenings."
During the new scan, the woman lies on her stomach. A camera swings up and
down, encircling the breast and capturing hundreds of pictures. The images
are combined to form a complete 3-D image.
Painless, 3-D MammogramsBecause of where many tumors are, they may be missed
by a mammogram but not with the new scanner. It can also detect tumors as
small as a tip of a pen. Mammograms detect lesions the size of a marble. Not
only can this scanner detect the smallest cancer tumors but it could detect
even the threat of cancer. Dr. Tornai is combining his scanner with one that
uses nuclear medicine to detect chemical changes in breast cells that could
signal cancer.
Making this scanner a more powerful tool to help women like Graham live to
finish not just one scrapbook ... But many, many more.
