The number of men who are diagnosed with prostate cancer in the UK (has increased in recent years. It is thought that this is because more men are having tests that detect very early prostate cancers that would previously not have been found. These tests include the PSA test. This is a blood test that measures a type of protein called prostate-specific antigen (PSA). A small amount of PSA is normally found in the blood, but men who have prostate cancer tend to have a high level of PSA in their blood.
The causes of prostate cancer are still unknown but there are some risk factors that increase a man’s chance of developing the disease.
