Yes. Nearly 90 percent of all prostate cancers are currently diagnosed at an early stage, and, owing to this, men are surviving longer after diagnosis. There are two tests that are used to detect prostate cancer in the absence of any symptoms. The first is the digital rectal exam (DRE), in which a doctor feels the prostate through the rectum to find hard or lumpy areas. The second is a blood test used to detect a substance made by the prostate called prostate-specific antigen (PSA).
