Benign prostatic hyperplasia, or BPH, is a condition of the prostate that men often develop as they age. As men age, the prostate gland is known to become enlarged. However, this does not mean cancer. BPH is a noncancerous growth of the cells within the prostate gland. By age 60, more than half of men have BPH. By age 85, about 90 percent of men have BPH, but only about 30 percent will have symptoms. An enlarged prostate can put pressure on the urethra which makes it difficult to urinate.
