Benign prostatic hyperplasia (BPH) is an enlarged prostate gland. The prostate gland surrounds the urethra, the tube that carries urine from the bladder out of the body. As the prostate gets bigger, it may squeeze or partly block the urethra. This often causes problems with urinating.
BPH occurs in almost all men as they age. BPH is not cancer. An enlarged prostate can be a nuisance, but it’s usually not a serious problem. About half of all men older than 75 have some symptoms.
