Method: Sera from 810 immunocompetent young individuals was analyzed for detecting the levels of alpha-fetoprotein (AFP), human Chorionic Gonadotropin (hCG), and lactate dehydrogenase (LDH) as indicators of testicular cancer and prostate-specific antigen (PSA) for prostate cancer. Result: Elevated levels of AFP, hCG, and LDH were found in 3,2, and 8 individuals respectively, but with an insignificant value from the total number. The level of PSA was slightly elevated in two individuals. Conclusion: Prostate cancer and testicular cancer have not been detected in volunteer men. None of involved men had elevated levels of all of three biomarkers of testicular cancer. The PSA level was not high enough to predict the presence of prostate cancer (PC).Keywords: Prostate cancer, testicular cancer, AFP, hCG, PSA
