什么是白血病?白血病是造血组织恶性增殖性疾病,也就是骨髓或淋巴组织等正常的造血细胞恶变成为恶性肿瘤细胞,也就是白血病细胞。这些坏细胞分化、增殖得非常快,在骨髓和其他造血组织中,白血病细胞大量增生和聚积,使正常的造血细胞受到排挤和破坏并侵犯其他组织器官。因此,常出现白细胞、红细胞和血小板减少,不同程度的贫血、出血、感染以及肝、脾、淋巴结肿大。白血病是常见的恶性肿瘤之一,其发病特点为:男性略多于女性;急性白血病比慢性多见;急性白血病中以急性髓细胞白血病为多,其次为急性淋巴细胞白血病;慢性白血病中以慢性髓细胞白血病为多,主要见于
What is leukemia? Leukemia is a malignant proliferative disease of hematopoietic tissue, that is, normal hematopoietic cells such as bone marrow or lymphoid tissue become malignant cells, that is, leukemic cells. These bad cells differentiate and proliferate very fast. In bone marrow and other hematopoietic tissues, leukemic cells proliferate and accumulate, which excludes and destroys normal hematopoietic cells and invades other tissues and organs. Therefore, often white blood cells, red blood cells and thrombocytopenia, varying degrees of anemia, bleeding, infection and liver, spleen, lymph nodes. Leukemia is one of the common malignant tumors, its incidence is characterized by: men slightly more than women; acute leukemia more common than chronic; acute myeloid leukemia, acute leukemia, followed by acute lymphoblastic leukemia; chronic leukemia with chronic Myeloid leukemia is more, mainly seen in
