Benign prostatic hyperplasia (BPH) is the enlargement of the prostate gland. The word "benign" means the cells are not cancerous. "Hyperplasia" means an increased number of cells. The prostate gland usually enlarges with age but doesn't always cause problems.
Chronic pelvic pain is constant pain felt in the lower abdominal region and the pain may persist for a longer duration, for more than six months.
