Clinical Trial Summary

The purpose of this study is to see if using Stereotactic Body Radiation Therapy/SBRT to treat a single metastatic site where cancer has worsened may be an effective treatment for people with oligometastatic breast cancer. Participants will stay on their usual drug therapy while they receive SBRT. This combination of SBRT to a single metastatic site and usual drug therapy may prevent participants' cancer from worsening in other metastatic sites or spreading.
