RESTON, Va -- January 21, 2010 -- Data from one of the largest mammography trials in history demonstrates that overall the radiation dose associated with digital mammography is significantly lower (averaging 22% lower) than that of conventional film mammography and that the reduction could be greater in women with larger and denser breasts.
"The ability to reduce the radiation dose for many women is another step forward for breast cancer screening with mammography -- which saves thousands of lives each year," said lead author R. Edward Hendrick, PhD, Breast Imaging Research, Northwestern University, Chicago, Illinois.
