ClinConnect Summary

This clinical trial is studying two different ways to deliver partial breast radiation therapy (PBI) to women with early-stage breast cancer after they have had surgery to remove their tumor. PBI targets the area where the tumor was located, which helps minimize radiation exposure to nearby organs like the lungs and heart. The trial will compare a single dose of radiation (single fraction) to the traditional method that involves multiple doses over a longer period (multiple fraction). This is important because many women, especially those living in rural areas, may find it difficult to travel for treatment that takes a long time.

To participate in the trial, women must be 40 years or older, have a specific type of early-stage breast cancer (less than 3 cm in size), and be able to provide consent for themselves. Participants will need to complete some questionnaires about their health, and they should be able to stay still during their treatment. Women who are pregnant or have certain medical conditions may not be eligible. This trial is still in the planning phase and has not started enrolling participants yet. If you or a loved one meet the criteria and are interested in learning more, it could be a good option to explore.
