How common is benign prostatic hyperplasia (BPH)?
Benign prostatic hyperplasia (BPH) is a widespread problem that increases with age, and affects nearly all men. It can start after the age of 40. Some men do not have any symptoms even though their prostate may have started to grow larger. BPH usually becomes more of a problem over time. Almost one in four men aged 40 – 49 years receive treatment for prostate problems, and this increases to three in every four men aged 70 years and older5.
