Dr. Pettaway is a Professor of Urology at The University of Texas MD Anderson Cancer Center in Houston, Texas. His clinical practice is based on treating patients with genitourinary malignancies, including penile, urethral, and prostate malignancies. The goal of his prostate-related studies is 1) to further define host and molecular markers of cancer progression, and 2) to reduce disparities in prostate cancer outcomes among African Americans and the underserved by studying both clinical and biologic correlates of aggressive disease. He has served as the Medical Director of the Prostate Outreach Project (POP), an initiative which has educated and screened over 5,000 men. Dr. Pettaway has also served as the Co-Director of a National Cancer Institute-funded study evaluating the influence of West African ancestry on the incidence and aggressiveness of prostate cancer among African American and Puerto Rican populations.
