This is a research study run by Mayo Clinic that collects blood samples and small tissue samples from biopsies in patients who have advanced breast cancer (cancer that has spread) or breast cancer that has come back after treatment. Researchers will study these samples alongside your medical records to better understand how breast cancer develops and progresses, with the goal of improving future treatments for patients like you.
Doctors need more information about how advanced breast cancer behaves at the cellular and genetic level to develop better treatments. By collecting samples from many patients, researchers can identify patterns and discoveries that may lead to new or improved therapies.

If you join, you will have a blood draw taken and may have a small tissue sample collected during a biopsy (if clinically needed as part of your regular care). Researchers will also review your medical records. The study is observational, meaning you are not receiving any new experimental treatment — researchers are simply gathering samples and information to study.
