Key information about breast cancer risk and development is found in 'junk' DNA
Date:12/16/2010

n with most risk are getting properly screened for breast cancer."

"One practical clinical application of this research is to have a test available that would allow us to tailor our screening better," Mullet said. "For example, we could lessen patients' time, expense, and worry if we could better determine which patients would need only a mammogram, as opposed to additional tests like ultrasound or screening breast MRI. This work may also give us genetic insight into the cause of the breast cancer that may develop in those 90 percent of patients who are not currently identified as high risk."

According to Garner, "There is a big gap between what is suspected and what is known about the genetics of cancer. While more work is needed to better understand how these changes play a role in cancer, these results can be used now as a new test for breast cancer susceptibility and, as our data suggests, for colon cancer susceptibility and possibly other types of cancer. We think this is just the beginning of what there is to be found in our junk DNA."
