Summary

This study is for people with invasive breast cancer who had chemotherapy before surgery, but whose tumors did not completely disappear. Researchers will take blood samples over time to look for tiny pieces of tumor DNA (ctDNA). The goal is to see if these DNA clues can predict whether the cancer will come back within 3 years. The study does not offer a new treatment, but aims to improve how we monitor and understand cancer risk.
