Chronic granulocytic leukemia is not hereditary because chronic granulocytic leukemia is not an inherited disease. At the same time, chronic granulocytic leukemia is a myeloproliferative disease, which is caused by a mutation in the patient’s DNA, chromosome 9 and chromosome 22 formed a fusion gene, also called the Philadelphia chromosome, after the formation of such a fusion gene, the cellular signaling system will be impaired, and the patient’s normal cell proliferation and division will be affected, resulting in the massive proliferation of mesophilic granulocytes, The patient’s normal cell proliferation and division will be affected, resulting in a large number of neutrophils and neutrophils proliferating in the bone marrow, and eventually the patient will have a series of symptoms such as abnormally high blood cells in the peripheral blood and a huge spleen. Chronic granulocytic leukemia is clinically divided into three stages: chronic, accelerated and acute. In recent years, with the application of complex kinase inhibitors, the prognosis of patients with chronic granulocytic leukemia has been significantly improved.
