Tempe, Ariz. – Technology being studied at Arizona State University could one day lead to an earlier diagnosis of breast cancer.

Researchers at ASU’s Biodesign Institute are working with a new 3D Imaging technology that pinpoints subtle changes in the nuclear structure of cells.

“The texture or the arrangement of the DNA in the nucleus is known to affect gene expression, which means which genes are more turned off or turned on, which changes as a function of disease state,” said Roger Johnson, a Research Laborator Manager at ASU and a co-author of a study of the technology.

Johnson went on to describe the technology.

“It’s kind of like a CAT Scanner, where the imaging is reduced to a sub-micron scale,” he said. “So it’s kind of like a cat-scanner for individual cells.

“Our hope is that these technologies will offer us the opportunity for early cancer detection,” said Johnson. “So that we can alert patients at the very early stages when the disease is still treatable.”

The technology was developed by a company called Visiongate, which hopes to get FDA approval this year. If it does, Johnson says the technology could be available in clinics around the country in two to three years.
