Tangential Radiation Therapy Without Axillary Dissection in Early-Stage Breast Cancer
The purpose of this study is to evaluate whether treatment to the axilla (area under the

lymph nodes.
- Patients will also receive 5 years of tamoxifen or another type of hormone therapy
determined by the medical oncologist.
- Follow-up visits will occur every 6 months and mammograms every 12 months.
