Overview

Biopsy may be helpful in the diagnosis of prostate cancer. Findings on biopsy suggestive of prostate cancer include increased gland density, small circular glands, basal cells lacking, and cytological abnormalities.

Biopsy

• A biopsy is used to diagnose prostate cancer. A prostate biopsy may be done if an abnormality was found during a DRE or transrectal ultrasound. It may also be done if the PSA level was high for a man’s age or has increased over time or rapidly.
• Biopsies of the prostate are usually done using transrectal ultrasound (TRUS). During a biopsy, tissues or cells are removed from the body so they can be tested in a laboratory. Several biopsies are usually taken from the prostate. They are collected from several areas of the whole prostate as well as from any suspicious areas.
• There are some methods for biopsy of prostate cancer include:
  • Transrectal biopsy
  • Transperineal biopsy
  • Transurethral biopsy
