Summary

This study is testing whether looking for tumor DNA in the blood can help predict if breast cancer will return in patients who had chemotherapy before surgery. Researchers will take blood samples over time from 180 people whose tumors did not fully disappear after chemo. The goal is to see if these DNA markers can give an early warning about cancer coming back.
