How is leukemia caused? 5

Leukemia is a malignant disease of the hematopoietic system, and leukemia cells are malignantly transformed from granulolet, erythrosome, megakaryocytic, lymphatic and monocytic cells of the hematopoietic system.

According to the theory of leukemia, leukemia is formed by the continuous proliferation and development of a first mutated stem cell, and it is generally believed that leukemia cells can be detected in the blood of patients when malignant cells in the body multiply to the level of 109 1011.

Leukemia cells have the same abnormal morphology, metabolism, and function as other tumor cells. It grows extremely vigorously and loses its ability to differentiate and mature and its corresponding functions. The difference is that in the case of individual leukemia cells, it is often difficult to distinguish them from normal hematopoietic cells of the same stage under light microscopy, and the malignant features are not as prominent as those of solid tumor (carcinoma or sarcoma) cells.

On the other hand, leukemia cells have greater discrete or migratory ability than solid tumor cells, enter the bloodstream earlier and infiltrate other organs and tissues, and generally do not form solid or localized masses or space-occupying lesions, and in rare cases, white sarcoma or green tumor (granulocytic sarcoma) can be formed.

Leukemia cells are differentiation disorders and maturation arrest caused by ** hormone, such as granulocytic cell arrest in the primitive stage, it is myelocytic leukemia, if it is stagnation in the promyelocytic stage, it becomes acute promyelocytic leukemia, and if it is stagnant in the more mature stage, it is chronic leukemia.

External factors are indispensable conditions for the onset of the disease, and there are three main types:

1. Physical: mainly radiation, ultraviolet rays, dust fibers represented by asbestos, and various harmful substances represented by cadmium and asphalt. Long-term exposure to these substances is 3 to 10 times more likely to become ill than non-exposure.

2. Chemical: Leukemia 80 is related to environmental pollution.

3. Biological: mainly caused by viruses and bacteria.

There are five main types of internal causes:

1. Heredity: The family history of leukemia has multiple generations of continuous high incidence, sometimes 3 or 4 times higher than that of the general population.

2. Spirit: It is related to mental depression and depression for a long time.

3. Immunity: The disease is prone to occur if the resistance is weakened or malfunctioning.

4. Bad habits: including smoking, drinking, picky eating, unscientific cooking, etc.

5. Nutrition: Lack or imbalance of vitamins, minerals, proteins, fats, sugars, fibers, etc. in the diet can cause internal environment disorders.

Leukemia is a malignant disease of hematopoietic tissues, also known as "blood cancer". It is characterized by the unrestricted proliferation of a large number of non-nucleated cells in the bone marrow and other hematopoietic tissues, and enters the peripheral blood, and the core of normal blood cells is obviously adsorbed, the disease ranks first among the malignant diseases of young people, the protist virus may be neurological negative tissue proliferation, and many factors such as mineral radioactivity of food, poisoning (benzene, etc.) or drug mutations, genetic predisposition, etc. may be pathogenic cofactors. According to the degree of immaturity of leukemia cells and the natural history of leukemia, it is divided into two categories: acute and chronic.

Chinese medicine. The poisonous poison enters the blood and wounds the marrow to cause blood stasis, and patients with leukemia show hepatosplenomegaly and abnormal elevation of white blood cells.

The spleen is weak and damp, and the blood vessels are full of dampness.
