But smoking does not result in more advanced stage diagnoses or aggressive breast cancers at the time of diagnosis. That is the result of an analysis of 35 years of data for more than 6,000 patients presented today at the American Society for Therapeutic Radiology and Oncology’s 49th Annual Meeting in Los Angeles.
“We hypothesized that tobacco use could result in more advanced stage or more aggressive breast cancer presentation, but that doesn’t appear to be the case,” said Matthew Abramowitz, M.D.,a resident in the radiation oncology department at Fox Chase Cancer Center. “There is no good news about smoking, but since about 10 percent of our patients are smokers, this research provides us with some relief. The question that remains is will smoking affect their survival?”
Abramowitz and his colleagues examined the medical records of 6,162 breast cancer patients at the time of initial diagnosis from 1970 to 2006 at Fox Chase Cancer Center in Philadelphia. Patient characteristics were prospectively collected by physician interview and questionnaire. Nine percent of the patients were current smokers when they were first seen for consultation.
“There was no statistically significant correlation between smoking and the stage of the disease or the aggressiveness of the tumor,” concluded Abramowitz. “The remaining question is does smoking affect how long these women live? In other words, does smoking affect the tumor’s behavior, its effect on the treatment to kill the cancer or recovery from treatment?”

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
