What is BPH (Benign Prostatic Hyperplasia)?
BPH is a non-cancerous (benign) enlargement of the prostate. Your prostate grew to normal size during your teenage years. Usually, the prostate grows to the size of a walnut. The prostate may begin to grow again when a man reaches middle age. The reasons for this growth are not fully known. By the age of 80, 80% of men have BPH. BPH causes symptoms in many older men.
