"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.

New discoveries predict ability to forecast dementia from single molecule

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
