All men have a prostate gland, located beneath the bladder, between penis and rectum. The urethra tube runs out of the bladder passing through the centre of the prostate and then to the penis, providing a path for urination. The muscles of the prostate also help to expel sperm from the body. Understanding the location of this gland and functions is key to explaining symptoms of prostate cancer. Incontinence or sexual disfunction can sometimes be caused by prostate cancer.
Causes are largely unknown but there is key evidence to show that the risk is higher with age; most cases are in men of more than 50 years of age. Prostate cancer is also more prevalent in black men and less in Asian men. There does appear to be a genetic trait as men whose father or brother were affected are at a higher risk. This form of cancer is common. In UK around 48.600 men are diagnosed every year.
