Prostate cancer is cancer of the prostate gland. Cancer is when abnormal cells start to divide and grow in an uncontrolled way. The cells can grow into surrounding tissues or organs, and may spread to other areas of the body.
Around 52,300 men are diagnosed with prostate cancer in the UK each year. In men, it is the most common cancer in the UK.
The number of people diagnosed with prostate cancer has increased over the last 10 years. This might be because more people are having PSA tests and the population is getting older.
