==Leukemia is a form of cancer that damages body's ability to make blood cells. The body makes too many of white blood cells, and few of red. Leukemia is a bone marrow disorder that occurs when an abnormal white blood cells replicates itself. Those white blood cells are much different from normal white blood cells and function abnormally. They don't fight off diseases as the should. The leukemia cells slowly move toward other areas in the body through the bloodstream, where they still continue to replicate themselves. ==

  **There are many different types of leukemia:** 


 * Acute lymphocytic leukemia- ** A type of leukemia that develops very fast, and is commonly found in children. But when it affects adults, they are usually 65 or older.
 * Chronic lymphocytic leukemia//-// ** This type of leukemia develops slower, and is found mostly in adults over the age of 55 or 60

 
 * Acute myeloid (myelocytic) leukemia-** Affects all ages, produces many of immature granulocyte myeloid cells; which replace the normal cells in the bone marrow.
 * Chronic myelogenous (myelocytic or myeloid) leukemia- ** Rare in children, occurs in an immature stem cell in the bone marrow when two chromosomes break apart and switch places. Which causes an altered gene that produces a protein that affects cell growth control. So then, the body produces too many of granuloctic white blood cells, many with the altered genes.
 * There are more that 28,000 new cases of leukemia in US each year.**
