The prostate is a gland of the male reproductive system approximately the size of a walnut. Anatomically, the prostate is found below the bladder with the upper part of the urethra passing through it. The prostate produces fluid that forms part of semen. It is surrounded by an elastic, fibromuscular capsule and contains glandular tissue as well as connective tissue.
With an incidence of 1.4 million new cases every year worldwide, prostate cancer is the second most common cancer in men just behind lung cancer. However, prostate cancer has a 70% lower mortality than lung cancer because it is detectable and treatable with the right tools.
