Summary

This study looks at whether a blood test can find tiny bits of tumor DNA left after breast cancer surgery. It includes 100 women with early-stage breast cancer that spread to 1-3 lymph nodes. The goal is to see if this test can help predict which patients are more likely to have their cancer come back, especially in African American women, who are often left out of such research.
