September 9, 2014 — An experimental regimen of once-weekly breast irradiation following lumpectomy provides more convenience to patients at a lower cost, results in better completion rates of prescribed radiation treatment, and produces cosmetic outcomes comparable to the current standard of daily radiation. These interim results of the five-year Phase II clinical trial using the experimental regimen were presented at the Breast Cancer Symposium 2014 in San Francisco by Anthony E. Dragun, M.D., vice chair and associate professor of radiation oncology at the University of Louisville.
