If a urologist suspects that a client might have prostate cancer. a core needle biopsy would be used to make a diagnosis of cancer.
How is Prostate Cancer Diagnosed?
You will probably require a prostate biopsy if the results of a PSA blood test, DRE, or other testing indicate that you may have prostate cancer.
A biopsy is a process in which the prostate is sampled in small amounts and examined under a microscope. Prostate cancer is typically diagnosed with a core needle biopsy.
Transrectal ultrasonography (TRUS), magnetic resonance imaging (MRI), or a "fusion" of the two imaging tests are typically used by the physician to examine the prostate during the biopsy. A thin, hollow needle is quickly inserted into the prostate through either the wall of the rectum (a transrectal biopsy) or a skin incision between the scrotum and anus (a transperineal biopsy). The prostate tissue is removed in the form of a tiny cylinder (core) when the needle is drawn out. This is done numerous times. Usually, the doctor will collect 12 core samples of the prostate from various locations.
Your biopsy specimens will be delivered to a laboratory where they will be examined under a microscope to determine whether they contain cancer cells. The biopsy leads to prostate cancer diagnosis.
