what causes an enlarged prostate

The actual cause of prostate enlargement, also known as benign prostatic hyperplasia (BPH), is unknown. However, most experts agree that it is linked to hormonal changes that occur as a man gets older. The balance of hormones in the body changes as men age, and this may cause the prostate gland to grow. Other factors that may contribute to the growth of the prostate include changes in the cells of the testicles. It is important to note that having an enlarged prostate does not raise the risk of developing prostate cancer.
