How does Leukemia start?

Answer 1

How leukemia begins depends in part on the type of leukemia present. All cancers involve an abnormal cell in the body which begins to multiple rapidly, crowding out the normal cells with immature cancerous cells. With leukemia, this abnormal cell growth is specific to bone marrow cells, but can differ a little as to which type. In lymphocytic leukemia, the bone marrow cells that are supposed to form the lymphocytes, a type of white blood cell, are affected. In myelogenous leukemia, the bone marrow cells responsible for forming the red blood cells, platelets, and certain other types of white blood cells are affected. Basically, leukemia starts when abnormal cells in the bone marrow start to proliferate.

Answer 2

You get leukemia when abnormal of control to such an extent that normal blood cells are unable to develop. Leukemia starts in the bone marrow---the soft, spongy material inside bones where blood cells develop from stem cells. Leukemia most often affects the white blood cells, which protect the body against infection. The disease begins when normal development of stem cells into white blood cells goes wrong, creating abnormal white blood cells. These white blood cells are immature that they can't fight viruses like they are suppose to do. Eventually the abnormal white cells overtake other types of blood cells, including red blood cells, which carry oxygen to the body tissues; and platelets, which enable the blood to clot. Leukemia therefore interferes with the blood's ability to clot and carry oxygen.Cells multiply out
you can't catch leukaemia of anyone because it isn't contagious.

In most cases of leukemia, there are too many abnormal white blood cells. These leukemia cells crowd out the normal blood cells in your bone marrow and build up in your lymph nodes, liver, and spleen. This makes it hard for your body to fight infections. No one knows what causes leukaemia.
i dont no

Answer 3

Leukemia, like any other cancer starts in the DNA. Some mutation of the DNA causes physical changes in the bone marrow producing one of the many types of Leukemia. There are actually a few types of Leukemia that are so slow growing that people live their entire lives without it being diagnosed and most often die of something else.
