Prostate Biopsy: A Comprehensive Guide
What Is a Prostate Biopsy?
A prostate biopsy is a medical procedure designed to extract small samples of prostate tissue for laboratory examination. This test is crucial in diagnosing prostate cancer or other prostate-related conditions. The tissue samples are analyzed under a microscope to detect abnormal or cancerous cells.
Prostate biopsies are generally recommended when other diagnostic methods, such as PSA (Prostate-Specific Antigen) blood tests or digital rectal exams, indicate potential abnormalities.
Why Is a Prostate Biopsy Performed?
Prostate biopsies are often conducted for the following reasons:
- Elevated PSA Levels: Persistent or rising levels of PSA in the blood can indicate prostate cancer or benign prostatic hyperplasia.
- Abnormal Digital Rectal Exam (DRE): If the prostate feels irregular, lumpy, or firm, further evaluation is required.
- Active Surveillance: For patients already diagnosed with prostate cancer, biopsies help monitor the disease’s progression.
Types of Prostate Biopsy Procedures
1. Transrectal Ultrasound-Guided Biopsy (TRUS)
This is the most common method. A thin needle is inserted into the prostate through the rectum using ultrasound guidance. TRUS biopsies are quick, minimally invasive, and widely accessible.
2. Transperineal Biopsy
In this procedure, the biopsy needle is inserted through the perineum (the area between the scrotum and rectum). This …
