"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.

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
