[47]: 694 In BPH, the majority of growth occurs in the transition zone (TZ) of the prostate. [47]: 694 In addition to these two classic areas, the peripheral zone (PZ) is also involved to a lesser extent. [47]: 695 Prostatic cancer typically occurs in the PZ. However, BPH nodules, usually from the TZ are often biopsied anyway to rule out cancer ...
Transition zone (TZ) 5% The transition zone surrounds the proximal urethra. [2] ~10–20% of prostate cancers originate in this zone. It is the region of the prostate gland that grows throughout life and causes the disease of benign prostatic enlargement. [6] [7] Anterior fibro-muscular zone (or stroma) —
The majority of treatable/treated cancers are of Gleason scores 5-7 and are detected due to biopsy after abnormal digital rectal exam or prostate specific antigen evaluation. The cancer is typically located in the peripheral zone usually the posterior portion, explaining the rationale of performing the digital rectal exam. [citation needed]
The International Prostate Symptom Score (IPSS) is an eight-question written screening tool used to screen for, rapidly diagnose, track the symptoms of, and suggest management of the lower urinary tract symptoms of benign prostatic hyperplasia (BPH).

A histopathologic diagnosis of prostate cancer is the discernment of whether there is a cancer in the prostate, as well as specifying any subdiagnosis of prostate cancer if possible. The histopathologic subdiagnosis of prostate cancer has implications for the possibility and methodology of any subsequent Gleason scoring . [ 1 ]
Prostate cancer is the second-most frequently diagnosed cancer in men, and the second-most frequent cause of cancer death in men (after lung cancer). [ 2 ] [ 3 ] Around 1.2 million new cases of prostate cancer are diagnosed each year, and over 350,000 people die of the disease, annually. [ 2 ]
The scope is passed through the urethra to the prostate where surrounding prostate tissue can then be excised. There are two types of modalities: There are two types of modalities: Monopolar TURP: A monopolar device utilizing a wire loop with electric current flowing in one direction (thus monopolar) can be used to excise tissue via the ...
