Acute lymphocytic leukemia (ALL) is the most common type of leukemia in children, representing 23 percent of cancer diagnoses among children younger than 15 years of age. However, the condition also occurs in adults.
ALL occurs when too many stem cells develop into a type of white blood cell called lymphocytes. These lymphocytes may also be called lymphoblasts or leukemia cells. This may cause infection, anemia, and easy bleeding. Acute lymphocytic leukemia can also spread to the central nervous system (brain and spinal cord).
Treatment options and prognosis can vary. In general, treatment for ALL may involve the following:
- Radiation therapy
- Chemotherapy with stem cell transplant.
