Anemia: People with anemia have a low number of red blood cells. Mild anemia often causes no symptoms. More severe anemia can cause fatigue, pale skin, and shortness of breath with exertion.

Chemotherapy and/or stem cell transplantation (bone marrow transplant) can treat leukemia, and sometimes result in a cure
