Prostate Cancer diagnosis

Three Cancer Prostate Diagnosis that often used:

• Biopsy
  If cancer prostate is detected, a biopsy is suggested. During a biopsy a urologist or radiologist obtains tissue samples from the prostate via the rectum. Biopsy done done by inserted a  biopsy gun inserts from rectum and removes special hollow-core needles (usually three to six on each side of the prostate) in less than a second. This cancer prostate diagnosis is guided by ultrasound image.
  
• Gleason score
  A samples is then examined under a microscope to determine whether cancer cells are present, and to evaluate the microscopic features (or Gleason score) of any cancer found. Prostate specific membrane antigen is a transmembrane carboxypeptidase and exhibits folate hydrolase activity. This protein is over-expressed in prostate cancer tissues and is associated with a higher Gleason score.
  
• Tumor Marker
  PSA presence can be known by using tissue sample. To determine the origin of malignant cells that have metastasized, tumor marker is used.
