Published in Cancer Weekly, November 7th, 2006

Certain types of brain cancer cells, called cancer stem cells, help brain tumors to buffer themselves against radiation treatment by activating a "repair switch" that enables them to continue to grow unchecked, researchers at Duke University Medical Center have found.

The researchers also identified a method that appears to block the cells' ability to activate the repair switch following radiation treatment.
