Summary

This study collects and stores breast cancer tissue from 600 people who took part in the TAILORx trial. Researchers will analyze the samples to find biological markers that can predict if the cancer will come back or resist hormone therapy and chemotherapy. No new treatments are given; the goal is to better understand the disease.
