What is the largest zone of the prostate?

The largest zone of the prostate is the peripheral zone. This area comprises about 70% of the prostate gland and is located posteriorly, surrounding the other zones. It is significant in terms of prostate pathology, as the majority of prostate cancers originate in this region. Due to its size and location, the peripheral zone is the most accessible area during digital rectal examinations and is often the focus during ultrasound evaluations. Understanding the anatomy of the prostate is crucial for interpreting imaging studies and diagnosing conditions such as benign prostatic hyperplasia and prostate cancer.
