Benign Prostate Hyperplasia (BPH)
BPH is the most common disorder of the prostate. Urinary symptoms due to BPH are thought to affect over half of men aged over 50. The incidence of BPH increases with age.
BPH is caused by an overgrowth of prostate tissue. These non-cancerous changes are due to:
- An increase in the number and size of prostate cells
As the prostate enlarges, it obstructs the urethra, which reduces the flow of urine from the bladder.
