Lifetime cancer risk from heart imaging low for most children, but rises with more complex tests

Children with heart disease are exposed to low levels of radiation during X-rays, which do not significantly raise their lifetime cancer risk. However, children who undergo repeated complex imaging tests that deliver higher doses of radiation may have a slightly increased lifetime risk of cancer, according to researchers at Duke Medicine. The findings, published in Circulation, represent the largest study of cumulative radiation doses in children with heart disease and associated predictions of lifetime cancer risk. Read more here.
