Prostate cancer screening

Screening for prostate cancer-checking for signs of the disease when there are no symptoms-is done with the digital rectal exam and the prostate-specific antigen (PSA) test. In the United States, about 75% of men who are age 50 or older have had a PSA test.¹

The number of deaths caused by prostate cancer has dropped over the past 20 years. The decrease has been linked to more early diagnosis with PSA testing and to better cancer treatment.²

Finding prostate cancer early leads you to some big decisions. Most prostate cancer grows slowly. And the side effects of treatment can change your quality of life-mainly not being able to have an erection (impotence) and not being able to control urination (incontinence). If you are around age 70 or older, these side effects may seem worse than early-stage cancer that may not grow much during your lifetime. But, especially for men 65 or younger, treatment makes the cancer less likely to grow and spread.³

The decision to have a PSA test for prostate cancer depends on your doctor's opinion and your own preferences. Some men will not want to live with the side effects of treatment; other men are more concerned about survival. It is important to learn all you can and talk to your doctor before making a decision.

Should I have a PSA test to screen for prostate cancer?

After reviewing all of the research, the U.S. Preventive Services Task Force (USPSTF) has not recommended for or against routine screening for prostate cancer using the PSA test or digital rectal exam.⁴
