Characterizing the Genomic Landscape of Prostate Cancer in Native American Populations (NAT-Geno)

This study is collecting tumor samples from Native American patients with prostate cancer in order to better understand the genetic makeup of the disease in this population. Prostate cancer is known to behave differently across different ethnic groups, and Native Americans are under-represented in cancer research. This is an observational study — no new treatment is being tested. **You may be eligible if...** - You are 18 or older - You self-identify as Native American - You have been diagnosed with prostate cancer (any stage), confirmed by a biopsy - You have archived tumor tissue available from a previous biopsy or surgery **You may NOT be eligible if...** - You do not identify as Native American - There is no archived tumor tissue available from your diagnosis Talk to your doctor to see if this trial is right for you.
