Study of Regional Radiotherapy in Biomarker Low Risk Node Positive Breast Cancer (TAILOR RT)

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.

In order to participate you must meet the following criteria:

• Have newly diagnosed histologically proven invasive carcinoma of the breast with no evidence of metastases.
• Are at least 40 years old.
• Patients may or may not have had adjuvant chemotherapy.

This is a partial list of inclusion and exclusion criteria.
