However, he also wondered if a negative result using this technique would cause people to avoid getting a biopsy.
"The short answer is no, because there is a risk that you can have breast cancer despite a 'benign' result," he said.
Annie Lehmann shares that sentiment.
She had a biopsy a few months ago, and the results indicated that she did have early-stage breast cancer.
She thinks the development of a non-invasive screening test would be great, but not at the expense of a definitive diagnosis.
"If the only way you're going to know 100 percent if you have cancer is to have a biopsy, I'd have the biopsy in a second," she said.
While the optical tomography/ultrasound combination does show some promise, other medical experts say it's too early to tell just how effective a tool it can be.
"We are not ready to move away from our current approach," said Hudis.
"Nine out of ten is not good enough," said Dr. George Sledge Jr., professor of medicine at the Indiana University Simon Cancer Center. "Remember that nine of ten is what screening mammograms currently pick up."
Despite the criticisms, Sherry Gavanditti is glad that research into non-invasive screening tests is ongoing.
"I fear for my daughters," she said. "If they can find something so they won't have to go through a biopsy, that would be wonderful."
