Read our Breast Cancer research guide →The FLEX Registry is collecting genetic test results and medical information from thousands of breast cancer patients across the United States. Researchers will use this information to study connections between genes and how well different treatments work, which could help doctors make better treatment decisions for future patients.
Doctors know that breast cancers are different from person to person, and genetic testing can help guide treatment choices. By gathering genetic data and treatment results from a large number of patients over time, researchers can discover new genetic markers that predict which treatments will work best for each patient.

You will have already received genetic testing through your doctor. The study will collect your genetic test results and track your medical information at several time points: when you enroll, during your treatment, and then at 1 year, 3 years, 5 years, and 10 years after your diagnosis. Your doctor will continue to manage your treatment according to standard cancer care guidelines — the study is simply gathering information about your results over time.
