Risk-based Screening Misses Breast Cancers in Women in Their Forties

摘要

CHICAGO - A study of breast cancers detected with screening mammography found that strong family history and dense breast tissue were commonly absent in women between the ages of 40 and 49 diagnosed with breast cancer. Results of the study were presented today at the annual meeting of the Radiological Society of North America (RSNA). "Screening recommendations for this age group continue to be debated," said Bonnie N. Joe, M.D., Ph.D., associate professor in residence and chief of women's imaging at University of California, San Francisco (UCSF). "Recent publications have suggested risk-based screening based on family history and breast density. However, our study shows that this approach would miss a significant percentage of invasive cancers and could potentially be dangerous."
