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.

Not a fit: Patients with conditions that impair their ability to provide informed consent or those with serious allergic reactions to local anesthetics may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment options for patients with recurrent or metastatic breast cancer.

How similar studies have performed: Other studies focusing on specimen collection for cancer research have shown success in advancing understanding and treatment, making this approach promising.
