Please tell me what does an enlarged prostate mean?

Enlarged prostate: See a urologist (u) for treatment of enlargement of the prostate (p) gland that either can be benign or malignant. In prostatic hyperplasia (BPH) and prostatic hypertrophy, prostate gland enlargement can cause urinary symptoms. Untreated p gland enlargement can block the flow of urine out of the bladder and can cause bladder, urinary tract or kidney problems. If malignant, see a u for treatment.
