Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase II trial studies how well radiation therapy before surgery works in treating patients with hormone receptor positive, HER2 negative breast cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
