PRECISION (Profiling Early Breast Cancer for Radiotherapy Omission): A Phase II Study of Breast-Conserving Surgery without Adjuvant Radiotherapy for Favorable-Risk Breast Cancer.

Brief description of study

If you have been diagnosed with breast cancer and are between the ages of 50 years and 75 years old, you may qualify for this study. The main goal of this study is to determine whether certain patients between the ages of 50 and 75 can safely omit radiation treatment after having a lumpectomy (surgery to remove cancer tissue from the breast) by using the investigational test Prosigna PAM-50 to attempt to identify which patients may not need radiation.
