Cancer screening tests — including the prostate-specific antigen (PSA) test to look for signs of prostate cancer — can be a good idea. Prostate cancer screening can help identify cancer early on, when treatment is most effective. And a normal PSA test, combined with a digital rectal exam, can help reassure you that it's unlikely you have prostate cancer. But getting a PSA test for prostate cancer may not be necessary for some men, especially men 75 and older.
Learn more about the risks and benefits of PSA tests for prostate cancer screening in the video below featuring R. Jeffrey Karnes, M.D., of the Department of Urology at Mayo Clinic. He addresses the controversy over PSA test use and its effectiveness in prostate cancer screening, as well as what constitutes the best screening methods and programs.
