Read our Breast Cancer research guide →This is a long-term follow-up study for people who participated in earlier breast cancer clinical trials. Researchers want to track how you're doing over time — including whether cancer comes back, how you're feeling, and any delayed side effects from treatment. By collecting information from hundreds of former trial participants, doctors can better understand the true, long-term benefits and risks of the treatments being tested.
Cancer doesn't always show its effects right away. Some side effects appear years after treatment ends, and we need to know how well treatments keep working over a lifetime. This registry helps doctors understand the real, long-term picture of these therapies.

After you agree to join, researchers will collect basic information about you and your treatment history using a secure online system. Then, at least once a year, your doctor will check in with you — either during regular follow-up visits, by phone, or by mail — to ask how you're doing, whether your cancer has come back, and how you're feeling. Your regular imaging tests (like mammograms) will continue as your doctor normally recommends. The study will continue for as long as you're willing to participate.
