For diagnosis of prostate cancer, your doctor will ask about your symptoms, examine you and may also ask about your medical history. Your doctor may do some of the following tests, or refer you to a urologist. A blood test to examine the amount of prostate-specific antigen(PSA) in your blood. PSA is a protein made by both normal and cancerous prostate cells. The test can be inaccurate as a high PSA level can be caused by other prostate conditions. A digital rectal examination(DRE)-an examination to feel your prostate through the wall of your back passage. If you have prostate cancer, it may feel harder than usual, or knobbly. A prostate biopsy, where your doctor uses a needle to remove a small piece of tissue from your prostate, may be done and the sample sent to a laboratory for testing.
