Acute Lymphoblastic Leukemia

The abbreviation ALL usually refers to acute lymphoblastic leukemia, a type of blood cancer that originates in the bone marrow and affects the cells responsible for producing a certain type of white blood cell. It is more common in childhood, although it can also occur in adults.

Common symptoms:

• Fatigue and paleness
• Fever or repeated infections
• Bruising or easy bleeding
• Bone pain and enlarged lymph nodes

Why it occurs: It results from uncontrolled growth of immature cells in the bone marrow; in most cases no preventable cause is identified.

Which specialist treats it? The hematologist coordinates the study, along with the pediatrician in children and the radiation oncologist when radiation therapy is required. In the presence of symptoms such as paleness, persistent fever, or unusual bleeding, it is advisable to have it evaluated as soon as possible by a professional.
