This statement is false. The vast majority (approximately 70-80%) of prostate cancers originate in the peripheral zone of the prostate gland. This is the outermost area of the prostate, located furthest from the urethra. This anatomical location is why early prostate cancer often causes no urinary symptoms; it has to grow quite large before it impinges on the urethra. In contrast, Benign Prostatic Hyperplasia (BPH) typically arises in the transition zone, which surrounds the urethra, which is why BPH commonly causes obstructive urinary symptoms even when the nodules are relatively small. The central zone is less commonly involved in cancer initiation.
