Gambar 1. Anatomi prostat 

The prostate gland is composed of different types of tissue, divided into zones:

• The peripheral zone (PZ) contains the majority of prostatic glandular tissue. The largest area of the peripheral zone is at the back of the gland, closest to the rectal wall. When a doctor performs a digital rectal exam (DRE) it is the back surface of the gland he is feeling. This is important because about 70-80% of prostate cancers originate in the peripheral zone.
• The central zone (CZ) is the area that surrounds the ejaculatory ducts. Only a very small percentage of prostate cancers begin here (less than 5%) and are thought to be more aggressive and more likely to invade the seminal vesicles.
• The transition zone (TZ) surrounds the urethra as it enters the prostate gland. It is small in young adults, but it grows throughout life, taking up a bigger percentage of the gland, and is responsible for benign prostatic hyperplasia (BPH, or normal gland enlargement that occurs with aging but can cause urinary problems). Roughly 20% of prostate cancers begin in this zone.

Benign Prostate Hyperplasia
Symptomatic men should have a digital rectal examination to assess the size and contour of the prostate.6 Prostate volume predicts the response to finasteride (Proscar) therapy. Finasteride is more effective if the prostate volume is greater than 40 mL (the normal prostate volume is 20 to 30 mL)
