Summary

This study looks at whether women with a certain type of breast cancer (hormone-sensitive, HER2-negative, with 1-3 positive lymph nodes and a low RecurIndex score) can safely avoid radiation therapy to the lymph nodes. Researchers will follow 635 participants over time to see how many have their cancer come back. The goal is to find out if skipping this treatment is safe for low-risk patients.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could show that some women with low-risk breast cancer can avoid unnecessary radiation, reducing side effects and treatment burden.
What could go wrong: This is an observational study, not a treatment trial, so it won't prove a new therapy works. Results may not apply to all patients, and there is a risk of recurrence if radiation is omitted.
