A study from the University of California, San Francisco (UCSF) revealed screening mammography that relied mostly on risk-based triage (strong family history, dense breast tissue, etc.) missed a significant number of cases of invasive breast cancer, especially among women aged 40 to 49 years old.
The study was led by Dr. Bonnie N. Joe, M.D., Ph.D., an associate professor in residence and chief of women's imaging at UCSF, and presented during the Radiological Society of North America (RSNA).
Dr. Joe explained that breast cancer screening for women between 40 and 49 years of age continues to be a subject of debate among experts. Several recent studies recommend risk-based screening based on family history and breast tissue density, but Dr. Joe and her co-investigators found this approach was not reliable enough, and would give rise to missed invasive breast cancer diagnoses.
