Men who have had PSA tests and a digital rectal exam that suggest prostate cancer. Men who are undergoing active surveillance.
What to Expect
Your urologist will give you antibiotics to prevent infection. An ultrasound technician will insert an ultrasound probe into the rectum to get ultrasound images of the prostate and locate areas suspected to be cancer. The urologist will use those images to guide the biopsies. The urologist will insert a device that contains a thin, hollow needle into the rectum and take tiny tissue samples from areas highlighted by the ultrasound. In some cases, the biopsy is performed through the perineum, the space between the anus and scrotum. A pathologist will mount the tissue samples on slides and examine them for signs of cancer.
