The number of white blood cells is not necessarily related to leukemia. Generally speaking, the number of white blood cells in leukemia patients tends to increase. The number of white blood cells in patients with acute leukemia is generally between 10 and 20 .

There is no necessary connection between white blood cell levels and leukemia. If white blood cells increase or decrease, leukemia and other malignant blood diseases must be ruled out. At this time, patients with increased or decreased white blood cells should cooperate with clinical improvement bone marrow examination, and pass some related examinations such as bone marrow cytology examination to determine whether they have hematological diseases such as leukemia. The main symptom of leukemia is fever. The number of leukemia cells is large, but they have no phagocytic function; the role of platelets in the body is mainly to block the gaps between blood vessels, rather than allowing red blood cells to flow out of the blood vessels.

Leukemia is a series of continuous clones of white blood cells. Due to the limited space in the bone marrow, white blood cells occupy the space where platelets grow, resulting in thrombocytopenia. Leukemia can lead to decreased immunity and infections, such as pneumonia and perianal infection; secondly, it can cause anemia, making the patient look pale and weak; thirdly, it can cause a variety of bleeding symptoms, such as skin ecchymosis or petechiae, gum bleeding, and even internal organs. Bleeding. The most serious thing is that leukemia cells can infiltrate the patient's organs and tissues, such as lymph nodes, liver or spleen; they may also infiltrate into kidney tissue, causing kidney damage, even kidney failure, and even death in severe cases.

Long-term treatment, especially repeated radiotherapy and chemotherapy, may cause patients to suffer psychological breakdown, become unwilling and unable to work and live normally, and ultimately lose confidence in their lives. Pay attention to rest and avoid strenuous activities. Pay attention to protective isolation to prevent infection. The family living environment should be relatively healthy and comfortable, and windows should be opened frequently to keep the indoor air fresh. Avoid contact with people with respiratory infections. Pay attention to oral and skin hygiene, change underwear frequently, and wash and dry clothes frequently. Keep warm and change clothes at any time according to changes in temperature.
