“In practice, I think there is a fine line between overtreating and undertreating breast cancer patients, and DCIS is squarely in that gray zone. Prior to DCISionRT, all DCIS patients got radiation. As an academic institution, we value and pride ourselves on following evidence-based literature and recommendations. DCISionRT is backed by strong evidence. That makes it easy to incorporate. And it is an important tool to use as a multidisciplinary group to determine if we should recommend radiation or not, because we are finding out that some women don’t actually need radiation.”
