What is a prostate biopsy?

ANSWER

A prostate biopsy uses transrectal ultrasound (through the rectum’s lining) imaging to guide several small needles through the rectum wall into areas of the prostate where abnormalities are detected. The needles remove a tiny amount of tissue. Usually, six or more biopsies are taken to test various areas of the prostate. The tissue samples are then analyzed in a laboratory. The results will help doctors diagnose disorders and diseases in the prostate.
