Summary

This trial shows that a new type of radiation therapy is effective and safe for treating breast cancer. It also spare more normal breast and lung tissue.

Who is the study for?
This trial is for early stage breast cancer patients who've had a lumpectomy with clear margins and no widespread disease. They must start radiotherapy within 10 weeks post-surgery, have localized disease confirmed by MRI, and be willing to follow the study's protocol.
What is being tested?
The trial compares two types of radiation therapy after lumpectomy: Intensity Modulated Radiotherapy (IMRT) versus standard 3D-conformal Accelerated Partial Breast Irradiation (APBI). It aims to see if IMRT better spares healthy tissue and improves outcomes.
What are the potential side effects?
Potential side effects include skin irritation, fatigue, changes in breast size or shape, pain or discomfort at the treatment site, and rare lung inflammation due to exposure during treatment.
