Study Summary

This trial will study how well radiation therapy before surgery works in treating patients with hormone receptor positive, HER2 negative breast cancer.

Who is the study for?

This trial is for adults with hormone receptor positive, HER2 negative breast cancer who are fit enough for treatment (ECOG 0-1). They must have a tumor that can be biopsied and measured on ultrasound, agree to see multiple specialists, and not be pregnant or breastfeeding. A clip should already be in place in the primary breast cancer.Check my eligibility

What is being tested?

The study is testing if giving radiation therapy before surgery can shrink tumors effectively in patients with specific types of breast cancer. The goal is to potentially reduce the amount of healthy tissue removed during surgery.See study design

What are the potential side effects?

Radiation therapy may cause skin irritation, fatigue, swelling or firmness where treated, changes in skin color, and rarely more serious effects like heart problems or secondary cancers.
