3D mammography detects more invasive cancers, reduced call rates -

3D Mammography is much more invasive cancers and reduce unnecessary reminders, according to a retrospective study published in June 25 issue of Journal of the American Medical Association ( JAMA ). The study includes data from University Hospitals Case Medical Center Seidman Cancer Center.

The study, the largest of its kind, focused on the impact of 3D mammography in a wide range of through the US sites, looking almost half a million mammograms 13 sites
main conclusions :.
• 41% increase in invasive cancer detected by mammography 3D
• 15% decrease unnecessary reminders to false alarms
• A 29% increase in the detection of all cancers within

"this study confirms what we already know: 3D mammography finds more, harmful invasive cancers that we want to find and save women the anxiety and the cost of having additional exams for which proves to be a false alarm, "said co-author of the study Donna Plecha, MD, director of breast imaging at UH Case Medical Center. "We already knew that the detection of breast saves lives and this study provides us with the data firm that 3D mammography is a better test to detect breast cancer early when it is treatable."

Hologic 3D mammography (breast tomosynthesis) was used exclusively in the study because they are the only 3D mammography manufacturer approved by the FDA. University Hospitals case Medical Center has been involved in the initial research on tomosynthesis and offered 3D mammography since 2011.

the system combines advanced digital mammography and tomosynthesis images generated to provide a more detailed picture, highly targeted breast. These images are then used to produce a series of thick slices a millimeter that can be considered as a 3D reconstruction of the breast. women see little difference between a conventional 2D mammography and 3D mammography. the exam takes only a few seconds more and the position is the same. The real difference is in the information available to the physician.

The technology gives radiologists the ability to identify and characterize individual breast structures and clearly see the features that might be obscured in a traditional 2D mammogram superimposing within the normal anatomy can mimic or mask a tumor . dense tissue and tissue structures that overlap can lead to false positive or false negative results with standard mammography.

Breast cancer is a significant health problem and statistics show that one in eight women will develop the disease in his life. The stage where the cancer is discovered influences survival and annual mammography for women after age 40 allows doctors to identify the smallest defects. In fact, when breast cancer is detected early and confined to the breast, the survival rate at five years is 97 percent.

"Breast cancers caught in the early stages of mammography are more likely to be cured and are less likely to require chemotherapy or as extensive surgery," said Dr. Plecha, also Assistant Professor at the school of medicine of Case Western Reserve University. "This study shows that 3D mammography is an effective screening tool, and we must make it accessible to all women."
