Researchers report that women with genetic mutations that put them at dramatically increased risk of developing breast cancer may also face a heightened risk from radiation used during medical screening and diagnosis.
The imaging tools that help doctors identify disease, injury or damage to the body have long been known to carry some risk of cancer, in large part because ionizing radiation can damage the genetic material in the body.

Scottish doctors report treating five children for injuries after swallowing liquid detergent capsules during the last year and a half.
The kids, all younger than 2, showed up in the emergency room with similar symptoms: drooling and stridor (breathing marked by a whistling sound caused by a narrowed airway). Most were treated with steroids and the placement of tubes to help the kids breath.
