Benign Prostatic Hyperplasia (BPH) is a condition caused by an enlarged prostatic gland. If the prostate, which is located just below the bladder and surrounds the urethra, grows too big, it blocks the flow of urine through the urethra because prostatic tissue takes up too much space. Contrary to prostate cancer, BPH is a benign condition, i.e. healthy tissue is not being destroyed. BPH is a space problem related to the squeezing of the urethra by the enlarged prostate.
