"In fact, a new study just presented at the annual meeting of the Radiological Society of North America (RSNA), concludes the low-dose radiation from annual mammography screening significantly increases breast cancer risk in women with a genetic or familial predisposition to breast cancer. This is particularly worrisome because women who are at high risk for breast cancer are regularly pushed to start mammograms at a younger age -- as early as 25 -- and that means they are exposed to more radiation from mammography earlier and for more years than women who don't have breast cancer in their family trees.
"For women at high risk for breast cancer, screening is very important, but a careful approach should be taken when considering mammography for screening young women, particularly under age 30," Marijke C. Jansen-van der Weide, Ph.D., an epidemiologist in the Department of Epidemiology and Radiology at University Medical Center Groningen in the Netherlands, said in a statement to the media. "Further, repeated exposure to low-dose radiation should be avoided."" (Read article)
