TUCSON, Ariz. (Ivanhoe Newswire) -- Bone scans are typically used to
check for osteoporosis, but now researchers say they could be one of the most
powerful predictors of breast cancer. Also, why having strong bones may put
older women at a greater risk.
At 64, two-time breast cancer survivor Ilya Sloan doesn't ask, "Why me?" but
she's often wondered, "How?"
"We definitely ask these questions of ourselves," she told Ivanhoe. "What did we
do? Did we have a role in this?"
University of Arizona researchers say results of a routine bone density test
could provide an important clue in predicting breast cancer risk in older, post
menopausal women.
"What we're showing in the study is that bone density may be an indicator or a
marker of something else which may link to breast cancer risk," Zhao Chen,
Ph.D., M.P.H., an epidemiologist at the University of Arizona in Tucson,
explained to Ivanhoe.
An eight-year study of 10,000 post menopausal women looked at factors like age,
race and history to estimate lifetime breast-cancer risk, as well as their
hip-bone mineral density T-score. They found older women with high bone density
are twice as likely to develop breast cancer.
"High bone density is a marker of increased risk for breast cancer," Dr. Chen
said. "We can use that piece of information to predict your breast cancer risk
in the future."
For Sloan, every new breast cancer study holds the promise for earlier
intervention, prevention, and the hope that future generations won't have to go
through what she did.
"That's the hope for my daughter and my granddaughter -- that we will be able to
prevent and if it occurs, cure this disease," Sloan said.
October is breast cancer awareness month. Doctors urge women to ask about bone
scans when they go to have their yearly mammograms.
