In situ hybridization probes - Prostate cancer
The prostate is a gland that is part of the male genitalia. Located under the bladder and in front of the rectum, like a ring it surrounds the urethra, it is normally the size and shape of a chestnut. It consists of glandular tissue surrounded by a fibromuscular layer (a combination of muscle and connective tissue). The prostate produces a fluid (prostatic fluid) which, together with sperm produced by the testicles, forms semen. The development and function of the prostate is influenced by male hormones (testosterone), which are made in the testicles. These hormones regulate the growth of the prostate and the formation of prostate fluid.
Prostate cancer is the most common type of cancer in men: it is estimated that 1 in 7 men will be diagnosed with it, most often in their 60s. Although no specific cause has been discovered, there is a genetic predisposition.
