Sara Brice was breezing through life---until a couple of years ago until she was informed she had dense breasts.

"My doctor mentioned it to me and at that point I'd been called back for an ultrasound and a biopsy," Sara said.

Fast-forward to present day and whiz-bang technology like tomosynthesis or 3D imaging which reveals tumors that before were hidden--especially in women with dense breasts.

"Now I can see that behind this straight tissue there is this little lump right there,” Dr. Patricia Krakos said while she pointed to a cancerous tumor.

Dr. Krakos is the medical director at the Sue A. de Mille Women’s Diagnostic Center at Texas Health Plano.

The 3D technology gained FDA approval last year and Texas Health is among only a handful of facilities across the country offering the enhanced imaging.

Dr. Krakos said because of the notification law more women are being informed and in some cases it causes undue concern.

"I think many women are getting the impression that because they have dense breast tissue that means they have a much greater risk of developing breast cancer or they'll be alarmed thinking that mammograms aren't worth it and they need other tests other than a mammogram," Dr. Krakos said.

Now a new study by the National Cancer Institute came to the same conclusion.

Researchers followed 9,000 breast cancer patients and found that those with very dense breasts were no more likely to die than women with breasts that weren't dense.

Texas, Connecticut, New York and Virginia are the only states with the notification law.

Dr. Krakos said the law and new 3D imaging technology allows for early detection.

"You're prognosis if the cancer is less than a centimeter is outstanding, “Dr. Krakos said “It's almost as if you didn't have a cancer especially in low grade cancer which we often find in the early stages like this."

As for Sara--Henda's law and 3D imaging offers a sense of comfort.

"Everything is fine,” Sara said. “It's the peace of mind knowing."
