It is my turned to be stunned by the content of eBeth's post - nobody said Mrs Edwards "was asking for it", the only reference was to statistical odds.
The odds originally quoted for Mrs. Edwards - carefully preceded by "about" - are to be found in all relevant studies of risk factors for breast cancer. On diagnostic exams (sometimes required by insurers) it's sometimes hard to find medics who agree on the increased risk of exams like mammograms, CT scans, any invasive procedure.
".... chairman of the American College of Radiology's Board of Chancellors, said that, although some may question comparisons to victims of Hiroshima, the study "qualitatively illustrates the fact that we are concerned about the doses of radiation delivered when there is no documentation of benefit to the population at large.."
