What is leukaemia?

The word cancer is used to describe all diseases that are characterized by the abnormal production of a certain type of cell within the organism. These cells have a much higher speed of growth and division than normal cells, which means that they gradually invade the body.

Leukaemia is the uncontrolled proliferation of an abnormal population of cells in the blood. These abnormal cells infiltrate the bone marrow, impeding the production of the remaining normal cells, and invading the blood and other organs.
