Leukemia is a cancer of the white blood cells. According to some statistics, millions of children and adults around the world suffer from this disease, and bout 90% of people with it are diagnosed in adults. If the child experiences it, large numbers of abnormal white blood cells will be produced in the bone marrow. These cells are defective so that they cannot perform their proper role of protecting the body against disease. It will affect the body’s production of other types of blood cells such as red blood cells and platelets, which will further cause anemia (low numbers of red cells) and bleeding problems.
It is reported that about 25% of all childhood cancers have this disease, and 2,200 American young people are influenced by it every year. Generally speaking, the leukemia includes acute and chronic form. It is common that the younger children ages 2 to 8 will get it, with a peak incidence at age 4. But all age groups can be impacted by it. If the children have had inherited certain genetic problems such as Li-Fraumeni syndrome, Down syndrome, Kleinfelter syndrome, neurofibromatosis, ataxia telangectasia, or Fanconi’s anemia, they will face a higher risk of developing leukemia.
The people with this disease will be bruised, bleed excessively, or develop pinprick bleeds easily. Furthermore, they also undergo the frequent infection, ranging from infected tonsils, sores in the mouth, or diarrhea to life-threatening pneumonia or opportunistic infections. However, the reasons why so people have it are natural and artificial ionizing radiation, a few viruses such as human T-lymphotropic virus, and some chemicals, notably benzene and alkylating chemotherapy agents for previous malignancies. When the people with it visit the doctors, they will tell some detailed information about it. When it comes to the stem cell treatment, the researchers find that two antagonistic proteins help keep this cancer at bay, pointing to new potential treatments.
