Blood in the stool in children is not necessarily a precursor to leukemia, but blood in the stool is one of the symptoms of leukemia and should be judged in conjunction with other symptoms in children.
Blood in the stool in children can be caused by a variety of reasons. If there is fresh blood in the stool, it may be caused by dry stool and anal breakage, most often due to anal fissures. If the stool is dark red, it may be a peptic ulcer causing gastrointestinal bleeding. In addition, bacterial dysentery and allergic purpura can also cause blood in the stool. In contrast, the precursors of leukemia may include fever, malaise, and bleeding. If it invades the digestive system and lesions occur in the intestinal tract, blood in the stool may also occur. If there are no symptoms other than blood in the stool, the possibility of leukemia can be basically ruled out.
Therefore, parents must pay attention to the case of blood in the stool in children, and if they suspect that it is a precursor of leukemia, they can take their children to the hematology department for a clear diagnosis.
