Black men are more likely than white men to have had a longer PSA screening interval before a prostate cancer (PCa) diagnosis, and are more likely to have undergone no PSA screening until being diagnosed.

SEER-Medicare data for 18,607 men diagnosed with PCa over eight years showed that longer intervals between PSA screenings were systematically associated with greater odds of diagnosis and advanced disease (Cancer Causes Control. 2010;21:1071-1080).
