African Americans is the correct answer.
Prostate cancer is a very common disease in the United Sates and northwestern Europe, but not very common in Asia, Central and South Americas and Africa. In the U.S, the incidence of prostate cancer is higher among African-American men because of their lower level of healthcare engagement, structural and cultural constraints. Thus, since African-Americans have, also, a strong genetic link responsible for the increase of early dissemination of prostate cancer, this group should receive information regarding the predisposition of the disease.
