what happens to a persons cells or organs when they have leukemia? -Symptoms of leukemia at the cellular level
The presence of a high level of abnormal white cells in blood indicates the leukemia disease. Though the levels of white blood cells are high, because they are abnormal, they cannot perform its defense function, hence, the patient is more exposed to infections. The leukemia cells can migrate to different tissues and parts of body.
