Prostate Biopsy

Biospy, Prostate

Test Overview

A prostate gland biopsy is a test to remove small samples of prostate tissue to be examined under a microscope. See an illustration of the prostate gland.

For a prostate biopsy, a thin needle is inserted through the rectum (transrectal biopsy), through the urethra, or through the area between the anus and scrotum (perineum). A transrectal biopsy is the most common method used. The tissue samples taken during the biopsy are examined for cancer cells.

A biopsy may be done when a blood test shows a high level of prostate-specific antigen (PSA) or after a digital rectal examination finds an abnormal prostate or a lump.
