Only men have a prostate. It is a small gland that sits below the bladder near the rectum. It surrounds the urethra, the passage in the penis through which urine and semen pass.
The prostate gland is part of the male reproductive system. It produces most of the fluid that makes up semen that enriches sperm. The prostate needs the male hormone testosterone to grow and develop.
The prostate is often described as being the size of a walnut and it is normal for it to grow as men age. Sometimes this can cause problems, such as difficulty urinating. These problems are common in older men and not always symptoms or signs of cancer.
What is Prostate Cancer ?
Prostate cancer occurs when abnormal cells develop in the prostate. These abnormal cells can continue to multiply in an uncontrolled way and sometimes spread outside the prostate into nearby or distant parts of the body.
Prostate cancer is generally a slow growing disease and the majority of men with low grade prostate cancer live for many years without symptoms and without it spreading and becoming life-threatening. However, high grade disease spreads quickly and can be lethal. Appropriate management is key.
