Use in men who might have prostate cancer PSA is mostly in semen, but a small amount is also in the blood. Prostate-specific antigen (PSA) is a protein made by cells in the prostate gland (both normal cells and cancer cells). Your doctor may also examine other areas of your body.Īfter the exam, your doctor might then order some tests. If you do have cancer, the DRE can sometimes help tell if it’s only on one side of the prostate, if it’s on both sides, or if it’s likely to have spread beyond the prostate to nearby tissues.
This might include a digital rectal exam (DRE), during which the doctor inserts a gloved, lubricated finger into your rectum to feel for any bumps or hard areas on the prostate that might be cancer. You might also be asked about possible risk factors, including your family history. If your doctor suspects you might have prostate cancer, you will be asked about symptoms you are having, such as any urinary or sexual problems, and how long you have had them.
