Prostate biopsy
Prostate Biopsy
A Prostate Biopsy (/prɒsteɪt baɪˈɒpsi/) is a medical procedure that involves the extraction of sample cells or tissues from the prostate gland to examine for the presence of prostate cancer. The term "biopsy" is derived from the Greek words "bios" (life) and "opsis" (view), indicating a procedure that allows for a detailed view into the life of cells or tissues.
Procedure
During a prostate biopsy, a needle is inserted into the prostate to collect a tissue sample. This is typically done through the rectum (transrectal biopsy), but can also be done through the perineum (transperineal biopsy). The procedure is usually guided by ultrasound imaging.
Types of Prostate Biopsy
There are several types of prostate biopsies, including:
- Transrectal ultrasound (TRUS) guided biopsy: This is the most common type of prostate biopsy. An ultrasound probe is inserted into the rectum to help guide the biopsy needle to the right area of the prostate.
- Transperineal biopsy: In this procedure, the biopsy needle is inserted through the skin between the scrotum and the rectum.
- MRI-guided biopsy: This is a newer type of biopsy that can be used if a TRUS biopsy does not find any cancer, but the doctor still suspects it is present.
Risks and Complications
Like any medical procedure, a prostate biopsy carries potential risks and complications. These may include infection, bleeding, pain, difficulty urinating, and false-negative results.
