Summary

This trial compares two types of radiation therapy to see which is more effective in treating patients with ductal breast carcinoma in situ or early invasive breast cancer.

Who is the study for?
This trial is for patients who've had breast-conserving surgery for ductal carcinoma in situ or early invasive breast cancer, with no tumor cells at the surgical margin. It's not open to those pregnant, with bilateral or advanced-stage breast cancer, more than 4 affected lymph nodes, metastases, previous breast cancers or radiation therapy in relevant areas.
What is being tested?
The study compares two types of radiation therapy: hypofractionated (higher doses over a shorter period) and standard treatment. The goal is to see if the shorter-duration treatment is as effective while potentially causing fewer side effects.
What are the potential side effects?
Radiation therapy can cause skin irritation, fatigue, swelling in treated areas, and changes to breast appearance. Long-term risks include heart problems and secondary cancers but vary between individuals.
