"Using IMRT, we are able to dramatically reduce the painful side effects of radiation, thereby improving the patient's quality of life," said Jean-Philippe Pignol, M.D., Ph.D., lead author of the study and a radiation oncologist at Sunnybrook Health Sciences Centre in Toronto, Canada. "Patients should be aware that breast IMRT has fewer side effects than standard radiation therapy and is now widely available."
The current standard of care for breast cancer is surgical removal of the cancer, followed by radiation to the breast to kill any remaining cells. The standard radiation technique uses two opposite radiation beams on the whole breast to target the cancer and can cause excess amounts of radiation to certain areas of the breast, increasing the risk of the patient developing sensitive, red, weepy skin that may blister and peel. The majority (80 percent) of severe skin burns occur on the breast crease, located between the bottom of the breast and the chest wall.
Using IMRT, however, radiation oncologists are able to control the intensity of each beam to better spare nearby healthy tissue, thereby minimizing the risk of too much radiation on a part of the breast and severe skin reactions. The treatment was able to significantly reduce this occurrence in women with large breasts, who are more likely to have severe skin reactions.
In this study, 358 patients were randomly assigned to receive either the standard breast radiation treatment or breast IMRT and were observed during and for six weeks after treatment.

Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
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...
