New Study: Annual MRI Screening Benefits Women With a History of Breast Cancer
Women with a history of biopsy-proven lobular carcinoma in situ (LCIS) appear to benefit from the addition of MRI to mammography for annual breast cancer screening. A retrospective study from Memorial Sloan-Kettering Cancer Institute presented Sunday at the 2010 RSNA meeting indicates the application of screening MRI for this at-risk population can double the cancer detection rate.
"Annual screening MRI is recommended by the American Cancer Society as an adjunct to mammographic screening for individuals who have sufficient genetic or family history, defined by a greater than 20% lifetime risk of developing cancer," according to Wendy B. DeMartini, MD, from the University of Washington Medical Center and Seattle Cancer Care Alliance. However, "There is currently insufficient evidence to support screening MRI for women with a personal history of treated breast cancer."
