The identification and screening of men at high risk for developing prostate cancer.

It is estimated that the lifetime risk of being diagnosed with prostate cancer is 1 in 5. The identification of risk factors, including age, African-American ancestry, family history, and possibly diet and environmental factors, has allowed health care professionals the opportunity to identify, screen, and study men at the greatest risk of developing prostate cancer. The risk factors, current screening tools, and the informed consent process for men participating in a prostate cancer screening program are outlined.
