What is leukemia?

Leukemia is a type of cancer that affects blood cells, in most cases white blood cells. It is caused by a transformation that occurs in the cells, before they become white blood cells. This transformation makes them cancerous, which means they reproduce constantly.

Leukemia can infiltrate the bone marrow and interfere with the production of normal blood cells. This could reduce the concentration of platelets and red blood cells which in turn leads to anemia and an increased risk of suffering from infections.

In addition, cancer cells can travel through the bloodstream and enter other organs such as the liver, spleen, kidneys and brain.
