Leukemia is a blood cancer caused by a rise in the number of white blood cells in your body. Those white blood cells crowd out the red blood cells and platelets that your body needs to be healthy. The extra white blood cells don’t work right.
Many types of Leukemia exist. Some forms of Leukemia are more common in children. Other forms of leukemia occur mostly in adults.
No one knows exactly what causes Leukemia . People who have it have certain unusual chromosomes, but the chromosomes don’t cause leukemia.
Common Leukemia Signs and Symptoms include :
Fever or Chills
Persistent Fatigue, Weakness
Frequent or Severe Infections
Losing Weight without trying
Swollen lymph nodes, enlarged liver or spleen
Easy Bleeding or Bruising
Bone Pain or Tenderness
Leukemia Causes and Risk Factors :
Previous Cancer Treatment : People who've had certain types of Chemotherapy and Radiation Therapy for other cancers have an increased risk of developing certain types of leukemia.
Genetic Disorders : Genetic abnormalities seem to play a role in the development of leukemia. Certain genetic disorders, such as Down syndrome, are associated with an increased risk of leukemia.
Exposure to Certain Chemicals : Exposure to certain chemicals, such as benzene — which is found in gasoline and is used by the chemical industry — is linked to an increased risk of some kinds of leukemia.
Family History of Leukemia : If members of your family have been diagnosed with leukemia, your risk of the disease may be increased.
