Technology has come a long way over the years -- and now the technology behind digital mammography is allowing life-saving screenings for the toughest patients to diagnose with breast cancer.

This is no small technological breakthough. It is a critical component for lowering the breast cancer death rate the American Cancer Society reports has declined 2.3 percent each year between 1990 and 2002. Since breast cancer is a treatable disease if caught early, digital mammography will up the odds of survival for women with this disease.

Digital mammography operates according to a computer-based technique that allows for digital manipulation of a breast X-ray. It exceeds the capability of film mammography -- and is much like the comparison between digital photography versus film photography. Both work. But one works better.

Studies show digital mammograms have a lot to offer. They detect tumors better in young women with dense breast tissue, for example. They allow for ease of storage and retrieval of images. And they can easily become part of a woman's electronic medical record.

There are still benefits of traditional mammography and women are still urged to use this less expensive option. They are also urged to conduct self-breast exams and to report for clinical exams with physicians. It's the whole package that contributes to comprehensive breast health, not just one isolated test. When used in combination with all other screening methods, digital mammography makes for a more accurate overall picture.
