Urologic diseases in America project: benign prostatic hyperplasia.

Benign prostatic hyperplasia (BPH), the most common benign neoplasm in American men, is a chronic condition that is associated with progressive lower urinary tract symptoms and affects almost 3 of 4 men during the seventh decade of life. Approximately 6.5 million of the 27 million white men who are 50 to 79 years old in the United States in 2000 were estimated to meet the criteria for discussing treatment.
