Causes of Acute lymphocytic leukemia



Acute lymphocytic leukemia happens when a bone marrow cell develops errors in its DNA. The errors tell the cell to continue growing and dividing, when a healthy cell would normally die. When this happens, blood cell production goes awry. The bone marrow produces immature cells that change into leukemic white blood cells referred to as lymphoblasts. These abnormal cells are unable to perform properly, and that they will build up and crowd out healthy cells.

It's not clear what causes the DNA mutations which will cause acute lymphocytic leukemia. however doctors have found that almost all cases of acute lymphocytic leukemia are not inherited.
