Summary

This study collects and stores breast tumor tissue from 600 patients who took part in the TAILORx trial. Researchers will analyze the samples to find biological markers that may predict whether cancer will come back or resist hormone therapy or chemotherapy. No new treatments are given; the goal is to learn from existing tissue to improve future care.
