GW professor to develop blood test for early detection of breast cancer

Today, patients with precancerous lesions, or early-stage breast cancer are usually diagnosed after a mammography screening. This method of detection can lead to false-positives and overtreatment, since mammography cannot determine whether pre-cancerous cells will actually turn into breast cancer. This may all change after Sidney Fu, M.D., professor of medicine at the George Washington School of Medicine and Health Sciences (SMHS), completes his study of early breast cancer detection using novel small RNA (microRNA or miRNA) biomarkers.
