Defining Cancer is a Difficult Task.

Today, we know that the cells of a tumour derive from an original cell which eventually – often decades before a lump even becomes physically or visibly noticeable - deviated from the normal, controlled division process. Every life begins as a single cell. This cell duplicates by means of cell division. Normal specialised cells are compatible with each other and function harmoniously together. They group together to form tissue, creating different organs.

In the early stages of cancer normal cells - often through various intermediate stages - transform into malignant cells that start to divide uncontrollably. In the event that the body’s defense mechanisms are not able to destroy them, more and more diseased cells are created initially forming a localised growth (tumour). The surrounding tissue is subsequently also proliferated (infiltration). Cancer cells can reach other body parts via the lymphatic and circulatory systems where they form new cancer growths (metastases). With leukaemia and certain lymphatic cancers, the cancer cells spread rapidly throughout the entire body.

Cancer is the collective term for around 150 different types of malignant organ tumours and diseases.
