What this Trial Is About
Researchers are collecting samples and clinical information from patients with recurrent or metastatic breast cancer, including male breast cancer, to better understand how these cancers develop, progress, and respond to treatment. This observational study aims to build a valuable resource to support future research in this area. Participants provide blood samples and fresh tissue from biopsies of metastatic lesions. The study does not involve any treatment intervention but includes collecting residual clinical tissue samples and reviewing medical records to gather comprehensive clinical data. During the study, patients undergo blood draws and tissue biopsies, and their medical history is reviewed. Researchers will measure responses to targeted therapies and changes in tumor cells as key outcomes. The study is led by Mayo Clinic and participation involves providing samples and clinical information, with no treatment assigned as part of the study.
