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.
