Study concludes that 3D mammography finds significantly more invasive cancers and reduces unnecessary recalls
The Journal of the American Medical Association announced Tuesday, June 24, that 3D mammography finds significantly more invasive cancers and reduces unnecessary recalls in a study that clears up confusion about the importance of 3D mammography.
Dr. Linda Greer, MD, medical director of the John C. Lincoln Breast Health and Research Center in Phoenix, co-authored this 3D mammography study of nearly half a million women, the largest, retrospective study of its kind.
"This study confirms what we already know: 3D mammography finds more of the invasive, harmful cancers we want found and saves women the anxiety and cost of having additional screenings for what turns out to be a false alarm," Dr. Greer said. "We are proud to be part of such an important study."
The study, led by Dr. Sarah Friedewald at Advocate Lutheran Hospital in Park Ridge, Ill., focused on the impact of 3D mammography at a diverse range of sites across the U.S., including the John C. Lincoln Breast Health and Research Center in Phoenix.
Key findings of the study include:
- 41 percent increase in invasive cancer detected with 3D mammography.
- 15 percent decrease in unnecessary recalls for false alarms.
- 29 percent increase in the detection of all breast cancers.
Women see little difference between a conventional 2D mammogram and a 3D mammogram. The exam takes just a few seconds longer and the positioning is the same.
The real difference is in the information available to the doctor. With 3D mammography, Dr. Greer personally reduced her rate of call backs for additional spot views by 93 percent. This benefits the patient because it reduces patient anxiety, lowers overall exposure to radiation and costs less due to unnecessary testing.
The Center has offered this technology since 2011, as the second Center in the country to offer 3D to its patients outside of clinical trials. This technology also detects cancer at an earlier, more treatable stage than 2D imaging.
The John C. Lincoln Breast Health and Research Center is the only imaging center in Arizona that screens all patients with 3D, low-dose imaging without additional charges. The Center is accredited by the American College of Radiology as a Breast Center of Excellence and is the first freestanding imaging center in Arizona to be accredited by the American College of Surgeons in the National Accreditation Program for Breast Centers for its high quality, comprehensive care.
