Blood is an important part of the body, transporting oxygen and various nutrients to every part of the body, meeting the metabolic needs of the body’s cells for growth, and transporting metabolic wastes produced by the body’s cells to the lungs and kidneys for elimination from the body. Blood is made up of blood cells and plasma. Blood cells include red blood cells, white blood cells and platelets, which in turn include granulocytes, monocytes and lymphocytes. Under normal circumstances, each blood cell proliferates according to certain rules, and each blood cell has a certain lifespan, at which point it will undergo apoptosis and be expelled from the body. When the value-added of a certain kind of blood cell is not regulated by the body, it can stay at a certain stage of blood cell development and proliferate indefinitely without apoptosis, and the result is a large number of blood cells at a certain stage of development in the body, such cells we call leukemic cells, the leukemic cells themselves do not perform its proper function, and the leukemic cells also destroy other blood cells and normal tissues and organs, at this time we can say that the person has leukemia. Depending on the origin and developmental stage of the leukemic cells, the leukemia can be divided into acute lymphoblastic leukemia, acute myeloid leukemia, chronic myeloid leukemia and chronic lymphocytic leukemia. Different types of leukemia have different treatment methods and different cure rates. However, leukemia is a type of disease that is potentially curable, so don’t give up on your life if you have leukemia.
