Anemia in children does not necessarily lead to leukemia, but leukemia can cause anemia in children. Anemia in children may be iron deficiency anemia, long time diet imbalance leads to too little iron in the body, there will be anemia, mainly manifested as pale, weakness, dizziness and other symptoms, but ischemic anemia will not directly induce leukemia, so anemia in children will not necessarily be leukemia. Although children’s anemia does not cause leukemia, but when the child has leukemia, it will lead to long-term anemia, usually accompanied by weakness, pale skin, fever, easy bleeding, shortness of breath, coughing and other symptoms, and in serious cases can be life-threatening. Parents should take their children to the doctor in time after the symptoms of anemia appear, in order to avoid delaying the condition.
