WASHINGTON, Nov. 1, 2016 /PRNewswire-USNewswire/ -- On Tuesday, Nov. 8, more than 140 medical societies worldwide will mark the International Day of Radiology (IDoR), celebrating the thousands of lives saved by the many contributions of breast imagers and radiation oncologists. IDoR 2016 will spotlight breast imaging and the essential role that radiology plays in the detection, diagnosis and management of breast disease. This special day, commemorating the 121st anniversary of the discovery of the X-ray by German physicist Wilhelm Roentgen, is sponsored by the American College of Radiology (ACR), Radiological Society of North America (RSNA) and European Society of Radiology (ESR). The day is also supported by the Society of Breast Imaging (SBI) and European Society of Breast Imaging (EUSOBI), and the radiation safety campaigns of Image Wisely® and EuroSafe Imaging. IDoR 2016 will also include celebrations during National Radiologic Technology Week (Nov. 6-12). Since mammography use became widespread in the 1980s, breast cancer deaths have plummeted nearly 40 percent. Besides markedly reducing the number of women who may die from breast cancer, mammograms detect cancer early — when it is most treatable. Many major medical organizations with expertise in breast cancer care, including the ACR, RSNA, the American Congress of Obstetricians and Gynecologists (ACOG), and SBI recommend that women start getting annual mammograms at age 40.
