What is a blood tumor?

Hematological tumors are malignancies that originate in the hematopoietic system. The most common hematological tumors include leukemia, lymphoma, multiple myeloma, myelodysplastic syndrome, and myeloproliferative tumors. Leukemia includes acute leukemia and chronic leukemia. Acute leukemia is the most common malignant tumor in young people under the age of 35. Lymphoma is divided into two categories, Hodgkin's lymphoma and non-Hodgkin's lymphoma, the former is mainly found in Europe and the United States, China is dominated by non-Hodgkin's lymphoma. Multiple myeloma, myelodysplastic syndrome and myeloproliferative tumors, more common in the elderly, of which the incidence of multiple myeloma accounts for 10% of hematological tumors, is a malignant tumor that cannot be cured at this stage. Myelodysplastic syndrome and myeloproliferative tumors, are characterized by abnormal proliferation of bone marrow, onset is slow, the course is longer, the patient to the end of the part can be transformed into acute leukemia, there are some patients died of bone marrow hematopoietic failure. In addition to multiple myeloma, hematopoietic stem cell transplantation is the only way to cure malignant hematologic tumors.
