Despite recommended guidelines, a number of women who received chest radiation for a childhood cancer have not had mammography screening for breast cancer in the previous 2 years, according to the results of a study published in the Jan. 28 issue of the Journal of the American Medical Association.
Kevin C. Oeffinger, MD, of the Memorial Sloan-Kettering Cancer Center in New York City, and colleagues, determined the breast cancer surveillance practices among a cohort of women who had childhood cancer treated with chest radiation. A questionnaire was administered to 551 women between June 2005 and August 2006.
The investigators found that 63.5% of the women aged 25 to 39 years and 23.5% of women aged 40 to 50 years had not had a screening mammogram in the previous 2 years. Nearly half (47.3%) of the women under 40 years of age reported never having a mammogram, the researchers report. Age predicted screening mammography; the likelihood of reporting a mammogram nearly doubled for every 5-year increase in age. The strongest predictor for screening mammograms among young women (aged 25 to 39 years) was a physician recommendation, the authors note.
"The risk of breast cancer after exposure to annual low-dose irradiation in the form of x-ray mammography should be explored in future studies as well as the role of MRI as a replacement for x-ray mammography rather than as an adjunctive examination in this group of young women," the authors of an accompanying editorial write.
