Prostate cancer in the Arab population: An overview

This review evaluated prostate cancer studies from around the world and investigated the causes of differences among them. Prostate cancer incidence and mortality rates showed significant discrepancies between countries and ethnicities. In North America as well as in other western countries, the most common cancer was found to be prostate cancer; however, it appears to be not as prevalent among men in the Middle East and North Africa. Statistics show that screening of prostate-specific antigen levels should be applied depending on ethnicity and age. Other environmental aspects such as dietary and androgenic factors are believed to have caused these differences.
