Cancer is a term that describes conditions where cells in our bodies behave abnormally, leading to lumps called tumours, or types of cancer within the blood such as leukaemia. There are many different types of cancer, and no cancer behaves in exactly the same way. Several different Cancer Teams help diagnose and treat cancer, depending on the symptoms and the type of cancer suspected. Cancer Services is the umbrella service that works with these teams to ensure that cancer is diagnosed quickly and treatment starts as soon as possible.
