The prostate is part of the male genitourinary tract. It is a walnut-sized gland, located underneath the urinary bladder, enveloping the proximal part of the urethra. The main function of the prostate is the excretion of a fl uid that forms part of the semen, but it also has an important role in controlling the fl ow of semen at the moment of ejaculation. Cancer of the prostate is a major health issue, it is mainly found in elderly men. In the United States, as an example for most Western countries, prostate cancer (PC) is the most frequently diagnosed non-skin cancer and is the second leading cause of cancerrelated mortality in men. A total of 192.280 new cases are estimated to be detected and 27.360 men are estimated to die of this disease in 2009 in the United States1. This means that 1 out of every 6 men will be diagnosed with the disease during their lifetime and 1 out of every 35 will die of it. The impressively high frequency of PC is further illustrated by autopsy studies, which show that as much as 55% of men in their fi fties and 64% of men in their seventies harbour the disease.
