If the test is positive, doctors usually cut out a piece of the prostate to see if it is cancerous. However, many people have false elevtions of PSA and get biopsies that they don't need. Prostate Specific Antigen is made by prostate cells and released into the bloodstream. Large prostates have more PSA, so a rise in PSA means that the gland is enlarging rapidly and this can be a sign of cancer. If you have an elevated PSA blood test, your doctor will check your prostate and order a sonogram to see if you have a nodule that may be a sign of cancer.
Most urologists recommend a biopsy done in their offices.
If your PSA is low, you may have difficulty ejaculating and fathering a child. A normal ejaculate clots and traps sperm. I'm Dr. Gabe Mirkin on Fitness. Journal of Urology. I Cevik, LN Turkeri, H Ozveri, Y Ilker, A Akdas.
