Benign prostatic hyperplasia

What is benign prostatic hyperplasia (BPH)?

BPH is the benign (non-cancerous) increase in the size of the bladder. The prostate grows during adolescence and early adulthood until it acquires its normal size. Generally the prostate grows until it reaches the size of a walnut. However it can start to grown again when a man reaches maturity. The reasons for this growth are not clearly understood. By the time a man is 80, more than 80% of men suffer from BPH. This condition produces symptoms in many older men.
