Treating breast cancer with MammoSite® resulted in a low risk of complications and was generally well tolerated, according to a University of Pittsburgh School of Medicine study presented today at the 47th annual meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Denver.
MammoSite, a type of breast brachytherapy (bray-kee-therapy), uses a single catheter inserted into the breast following lumpectomy, or surgical removal of a tumor, to deliver a high dose of radiation. Once the catheter is inserted, a tiny balloon is inflated and loaded with radioactive seeds that deliver prescribed levels of radiation to targeted tissue surrounding the tumor site.
"MammoSite is a type of partial breast irradiation that delivers radiation from the inside of the breast directly to the tumor site where cancer cells are most likely to reside," said Sushil Beriwal, M.D., assistant professor at the University of Pittsburgh School of Medicine and medical director of radiation oncology at Magee-Womens Hospital of the University of Pittsburgh Medical Center (UPMC). "Ours is one of the largest single-institution studies to confirm that it does this safely and with an acceptable level of toxicity."

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
