As these sound waves are reflected back to the transducer, it records and transmits them to the monitoring device, which creates the images (sonograms). In the presence of an abnormal PSA and/or if the results of TRUS are suspicious for prostate cancer, a prostate biopsy is performed.
Prostate-specific antigen (PSA) is a protein produced by the prostate and found in the blood. A PSA blood test can detect prostate cancer early, but it may not save lives. Low PSAâusually about 4 nanograms per milliliter of blood or lessâsuggests that a man does not have prostate cancer. But higher levelsâtaking into account age and race (PSA rises naturally with age)âmay indicate the presence of cancer. But so many factors influence PSA that a single test is never enough to diagnose prostate cancer. If you do have high levels of PSA, your doctor may suggest a prostate biopsy or another test to determine if you have cancer.
