The study found that six-month short-interval follow-up examinations had an 83% sensitivity, which is similar to the sensitivity of other diagnostic mammograms, said Erin J. Aiello Bowles, MPH, lead author of the study from the Group Health Center for Health Studies. High sensitivity means identifying a high proportion of “true positives” (actual cancer cases) and a low proportion of “false negatives” (cases mistakenly deemed benign).
The study included 45,007 initial short-interval follow-up mammograms. “Short-interval follow-up mammograms are done to monitor for changes in ‘probably benign’ breast lesions (findings seen on mammograms that have a very low probability of being cancer). Because the probability of cancer is so low, we don’t want to put the patient through an unnecessary biopsy, which is an invasive procedure that increases both patient anxiety and medical costs,” said Aiello Bowles. “At the same time, we want to closely monitor these patients, because changes in ‘probably benign’ lesions occasionally mean cancer, and we want to detect the cancers as early as possible,” she said. In the study, 360 women with “probably benign” lesions were diagnosed with breast cancer within six months; and 506 women were diagnosed with cancer within 12 months (altogether about one in 100 of the “probably benign” lesions), Aiello Bowles said.
“The Breast Imaging-Reporting and Data System (BI-RADS) recommends that women with a BI-RADS category 3 (probably benign) lesion get a six-month diagnostic mammogram, with follow-up continued for the next two to three years until long-term stability is demonstrated,” said Dr. Edward Sickles, a coauthor and radiologist involved in the study from the University of California San Francisco. “This study emphasizes that radiologists and patients need to follow that recommendation,” he said.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
