Does Diagnostic Radiation Increase Breast Cancer Risk in Women with BRCA Mutations?

European questionnaire-based study leaves the question unanswered.

Because ionizing radiation can damage DNA, diagnostic x-ray exposure in individuals with defects in DNA repair mechanisms (such as those associated with BRCA1 and BRCA2 mutations) could lead to excess risk for cancer. Investigators surveyed women with documented BRCA1/2 mutations in the Netherlands, France, and the U.K. to evaluate any association between radiation exposure and later development of breast cancer. Questionnaires were administered to BRCA1/2 carriers from 2006 to 2009 to elicit their recollections of the type and number of diagnostic procedures they had received in their lifetimes. Estimates of radiation doses to the breast during each type of diagnostic procedure (mammography, fluoroscopy, and computed tomography and convent…
