Prostate Cancer

Prostate cancer and prostate gland anatomy and function. The gland needs a hormone called testosterone to perform its function. This hormone helps the male body to develop and maintain his male characteristics and sex function. Testosterone is transformed into dihydrotestosterone by an enzyme. Dihydrotestosterone has crucial importance for the normal gland growth. This hormone can cause a decrease or an increase in the gland, and it plays an important role in the development of  this type of cancer.

The prostate is a  gland and it  is located below the bladder. The pipelike tube passes through a small hole in the center of the gland. This anatomic feature has significant clinical importance. Many elderlies suffer from an enlargement of this gland. This enlargement is benign and is called benign hypertrophy. The latter causes the gland to squeeze the urethra and may close the urethra completely. The result of this condition is urinary retention.
