Screening aims to detect cancer at a very early stage, when it is more curable, or to find changes in cells that could become cancerous if not treated. Often this will be before it causes symptoms.
If you have any symptoms that may be caused by cancer, your GP can refer you for tests to find out more. Any symptoms that continue for a number of weeks and don’t get better should be checked with your GP. There is more information on our page about signs and symptoms of cancer|.
