Cancer

Cancer is a group of conditions where the body's cells begin to grow and reproduce in an uncontrollable way. These cells can then invade and destroy healthy tissue, including organs.

Cancer sometimes begins in one part of the body before spreading to other parts. This process is known as metastasis.

How common is cancer?

Cancer is a common condition and a serious health problem. Excluding non-melanoma skin cancer, there are around 9,000 new cases diagnosed each year in Northern Ireland.

It is estimated that one in two people will develop cancer at some point in their lives. Being aware of the signs and symptoms linked to the condition can help with early detection. This is important because the earlier cancer is detected, the better the chances of successful treatment.
