New research from scientists at
University Hospitals (UH) Case Medical Center and Case Western Reserve
University School of Medicine indicate that in women in their 40s
undergoing routing screening, mammography helps find smaller tumors
that are less likely to require chemotherapy.
The findings, published in the February issue of American Journal of Roentgenology,
contradict 2009 guidelines from the U.S. Preventive Services Task Force
recommending against annual mammography screening for women in that age
range. The American Cancer Society, the American College of Radiology,
and other professional societies recommend annual examinations
beginning at age 40 years.
In the study, the authors compared women
undergoing routine mammography screening and women with a symptom
requiring a diagnostic workup. They found that patients undergoing
screening mammography were diagnosed at earlier stages with smaller
tumors and were less likely to require chemotherapy. The researchers
also found that screening detects high-risk lesions, which may lower
future breast cancer risk.
