A pilot randomized clinical trial of a smartphone-based application to support at-home PSA screening and culturally tailored prostate cancer education for African American men: A study protocol.

Background: Prostate cancer is the most diagnosed cancer in Black/African American men (AA) and the second‑leading cause of cancer-related deaths. A prostate-specific antigen (PSA) blood test is an early detection screening tool for prostate cancer, but uptake of PSA screening remains low among AA men. Greater PSA screening rates among AA men, coupled with earlier treatment, may reduce disparities in prostate cancer outcomes, including mortality.
