Leukemia is a form of cancer that affects the body's blood making system, including the lymphatic system and bone marrow. Leukemia is either acute (coming on suddenly) or chronic (lasting a long time). Chronic leukemia rarely affects children, while acute leukemia affects both adults and children.
early symptoms of leukemia are like symptoms of the flu or other common diseases. Symptoms include:
aches in bones or joints
swollen glands (lymph nodes)
unexplained weight loss
bleeding or swelling of gums
an enlarged spleen or liver, or a feeling of abdominal fullness
slow healing cuts, nosebleeds or frequent bruises
