The purpose of this study is to compare the effects on low risk breast cancer receiving usual
care that includes regional radiation therapy, with receiving no regional radiation therapy.
Researchers want to see if not giving this type of radiation treatment works as well at
preventing breast cancer from coming back.
Women with node positive breast cancer normally will receive endocrine therapy and some may
receive chemotherapy to help prevent the cancer from coming back. Many women will also
receive radiotherapy to the whole breast/chest area and the surrounding lymph glands (called
regional radiotherapy). No one really knows whether patients with low risk breast cancer need
to receive regional radiotherapy. Some women may be getting regional radiotherapy who do not
need it. These women may be exposed to the side effects of their treatment without benefit.
If you are confirmed eligible after full screening, you will be required to understand and sign the informed consent if you decide to enroll in the study. Once enrolled you may be asked to make scheduled visits over a period of time.
Every year hundreds of thousands of volunteers step forward to participate in research. Sign up as a volunteer and receive email notifications when clinical trials are posted in the medical category of interest to you.
