Leukemia: the causes

The origin of the disease is rarely found. However, some environmental causes have been identified:

  • Ionizing radiation,
  • pollution,
  • exposure to carcinogenic chemicals (pesticides, benzenes, solvents, etc.) ..

These causes have been incriminated in scientific studies.

In some rare cases, the causes of leukemia are hereditary, or the side effects of cancer treatment.

What makes the disease so serious is that leukemia causes a disturbance in the production of white blood cells in the bone marrow (place of production of blood cells).

  • In acute leukemia, white blood cells are produced in excess and do not reach maturity: they are therefore young cells that go into the blood.
  • In chronic leukemias, the cells are less immature but do not work well. Also note that some viruses are involved in some leukemias (but rare).

Result: these white blood cells do not provide their role of protection of the body. And, in addition, prevent other blood cells from developing. The body is left with an excess of inefficient white blood cells and a lack of platelets and red blood cells. These cells have an essential function for the body.

Red blood cells carry oxygen and carbon dioxide between the lungs, organs and muscles. As for platelets, they serve to coagulate when there is a wound. They make a sort of bandage around the wound of the blood vessel to prevent the blood from coming out. This is why the lack of production of blood cells caused by leukemia is responsible for the symptoms of leukemia.
