No Clear Cut-off Age to Stop Breast Cancer Screening, Large US Study Finds
There is no evidence of a clear cut-off age at which women should stop being screened for breast cancer, according to data from the largest-ever study on screening mammography outcomes. The findings were recently presented at the Radiological Society of North America (RSNA) 102nd Scientific Assembly and Annual Meeting in Chicago. Breast cancer screening currently relies on regular mammography imaging exams throughout a woman's life, but researchers have not been sure when women should stop being screened for breast cancer. "There has been a lot of controversy, debate and conversation regarding the different breast cancer screening guidelines, even among major national organizations, over the past few years," Cindy S. Lee, MD, assistant professor in residence at the University of California, San Francisco, said in a press release. "All prior randomized, controlled trials excluded women older than 75, limiting available data to small observational studies," she said. As a result, the United States Preventive Services Task Force (USPSTF) issued new guidelines in 2009 stating there wasn't enough data to assess the benefits and harms of mammograms in women ages 75 and older. The researchers used data from the National Mammography Database to assess whether women could stop getting mammograms at a particular age. They analyzed data from more than 2.5 million women ages 40 or older who underwent a total of more than 5.6 million mammograms, performed from 2008 to 2014 in 150 facilities across 31 U.S. states. Patients were divided according to their age into groups of five-year intervals, and each age grou
