Acute Lymphocytic Leukemia

Leukemia is cancer of the white blood cells. White blood cells help your body fight infection. Your blood cells form in your bone marrow. In leukemia, however, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. In acute lymphocytic leukemia (ALL), there are too many of specific types of white blood cells called lymphocytes or lymphoblasts.
Possible risk factors for ALL include being male, being white, being older than 70, previous chemotherapy treatment, or exposure to radiation.
Symptoms of ALL include:

• Weakness or feeling tired
• Fever
• Easy bruising or bleeding
• Bleeding under the skin
• Shortness of breath
• Weight loss or loss of appetite
• Pain in the bones or stomach
• Pain or a feeling of fullness below the ribs
• Painless lumps in the neck, underarm, stomach, or groin

Tests that examine the blood and bone marrow diagnose ALL. Treatments include chemotherapy, radiation therapy, stem cell transplants, and targeted immune therapy. Once the leukemia is in remission, you need additional treatment to make sure that it does not come back.
