Prostate cancer: The facts

Here are the main facts about prostate cancer:

• Only men have a prostate gland.
• Usually, a healthy prostate is the size and shape of a walnut and grows bigger as you get older.
• It sits underneath the bladder and surrounds the urethra tube.
• Its main function is to help make semen – the fluid that carries sperm.
• Prostate cancer can develop when cells in the prostate start to grow in an uncontrolled way.
• Prostate cancer often grows slowly to start with and may never cause any problems.
• But some men have prostate cancer that is more likely to spread. This needs treatment to stop it spreading outside the prostate.
