A prostate biopsy is the removal of tiny samples of prostate tissue to examine it for signs of prostate cancer.
The prostate is a small, walnut-sized gland just under the bladder. It wraps around the urethra, the tube that carries urine out of the body. The prostate makes semen, the fluid that carries sperm.
There are three main ways to perform a prostate biopsy.
Transrectal prostate biopsy - through the rectum. This is the most common method.
Other prostate biopsy methods are used, but not very often. These include:
Transurethral - through the urethra.
Perineal - through perineum (the skin between the anus and the scrotum).
Your provider will inform you about the risks and benefits of the biopsy. You may have to sign a consent form.

A biopsy is done to check for prostate cancer.
Your provider may recommend a prostate biopsy if:
Normal results from the biopsy suggest that no cancer cells have been found.
A positive biopsy result means that cancer cells have been found. The lab will give the cells a grade called a Gleason score. This helps predict how fast the cancer will grow. Your doctor will talk to you about your treatment options.
The biopsy may also show cells that look abnormal, but may or may not be cancer. Your provider will talk with you about what steps to take. You may need another biopsy.
