What is the prostate?
The prostate is a gland. Only men have a prostate. The prostate is usually the size and shape of a walnut. It sits underneath the bladder and surrounds the urethra, which is the tube men urinate (pee) and ejaculate through. The prostate’s main job is to help make semen – the fluid that carries sperm.
What is prostate cancer?
Prostate cancer can develop when cells in your prostate start to grow in an uncontrolled way. Prostate cancer often grows slowly and may never cause any problems. But some prostate cancer grows quickly and has a high risk of spreading. This is more likely to cause problems and needs treatment to stop it spreading.
