Cancer is a condition where cells in a specific part of the body grow and reproduce uncontrollably. The cancerous cells can invade and destroy surrounding healthy tissue, including organs.
Cancer sometimes begins in one part of the body before spreading to other areas. This process is known as metastasis. There are over 200 different types of cancer, each with its own methods of diagnosis and treatment. You can find out more about specific types of cancer by clicking on the links below.
Spotting signs of cancer
Changes to your body’s normal processes or symptoms that are out of the ordinary can sometimes be an early sign of cancer.

In many cases, your symptoms will not be related to cancer and will be caused by other, non-cancerous health conditions. However, it is still important that you see your GP so your symptoms can be investigated.
