A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to gather blood samples and fresh tissue from biopsies of metastatic lesions in patients with recurrent or metastatic breast cancer, including male breast cancer. The collected specimens and clinical data will help enhance the understanding of the disease's development, progression, and treatment options. Participants will undergo blood sample collection, tumor biopsy, and have their medical records reviewed as part of the study. The study is being conducted at the Mayo Clinic in Rochester, Minnesota.
