The prostate is a gland of the male reproductive system. In adults, it is about the size of a walnut, [3] and has an average weight of about 11 grams, usually ranging between 7 and 16 grams. [4] The prostate is located in the pelvis. It sits below the urinary bladder and surrounds the urethra.
Misrepair-accumulation aging theory [44] suggests that development of benign prostatic hyperplasia is a consequence of fibrosis and weakening of the muscular tissue in the prostate. [45] The muscular tissue is important in the functionality of the prostate, and provides the force for excreting the fluid produced by prostatic glands.
Five-year survival rates range from 30–99%, depending on stage. [1] Prostate cancer is the uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder.

The prostatic urethra, the widest and most dilatable part of the urethra canal, is about 3 cm long.. It runs almost vertically through the prostate from its base to its apex, lying nearer its anterior than its posterior surface; the form of the canal is spindle-shaped, being wider in the middle than at either extremity, and narrowest below, where it joins the membranous portion.
Gleason score is calculated from grade as described in the text. The Gleason grading system is used to help evaluate the prognosis of men with prostate cancer using samples from a prostate biopsy. Together with other parameters, it is incorporated into a strategy of prostate cancer staging which predicts prognosis and helps guide therapy.
