What can I write in the handwritten newspaper about leukemia? Can you write it down?

Leukemia is a malignant disease of hematopoietic tissue, also known as "blood cancer". Its characteristic is that a large number of leukemia cells in bone marrow and other hematopoietic tissues proliferate indefinitely and enter peripheral blood, while the production of normal blood cells is obviously inhibited. This disease ranks first among the malignant diseases of young people, and its cause is still not completely clear. Virus may be the main pathogenic factor, but there are many other factors such as radiation and chemical poison (benzene, etc.). ) or drugs and genetic qualities that may be auxiliary factors. According to the immature degree of leukemia cells and the natural course of leukemia, it can be divided into acute and chronic types.

Leukemia is a malignant tumor of hematopoietic system and one of the most common malignant tumors in China. According to a retrospective survey, the incidence of leukemia in various regions ranks sixth among all kinds of tumors. Leukemia is the malignant proliferation of leukemia cells in hematopoietic organs such as bone marrow, spleen and liver, which can enter the blood circulation and infiltrate all tissues and organs of the whole body. Clinically, there are different degrees of anemia, bleeding, infection and fever, liver, spleen, lymph nodes and bone pain. There are more men than women in leukemia patients.

It is characterized by malignant and infinite proliferation of leukemia cells in bone marrow and other hematopoietic tissues, infiltrating all tissues and organs of the whole body and producing different symptoms; Peripheral blood cells have quantitative and qualitative changes. Every day, bone marrow can produce tens of billions of new blood cells, most of which are red blood cells. However, leukemia patients produce more white blood cells than they actually need, and most of them are immature cells, and their survival time is longer than normal people. Although there are many white blood cells, they are not as anti-infective as normal white blood cells. This increase in white blood cells in the body will directly affect the functions of some important organs and the production of normal healthy blood cells. Because of the malignant proliferation of tumor cells, it inhibits the production of red blood cells and platelets to stop bleeding, and even there are not enough normal white blood cells to resist infection, which is easy to be injured, bleeding and infected.
