一白血病的易患因素1 病毒感染人类白血病只有成人T细胞白血病(ATL)肯定是由病毒引起的,除ATL外其他类型白血病尚无法证实具有传染性。2 遗传因素白血病患者不会直接把疾病传给后代,但白血病在某些家庭有聚集性,近亲婚配的人群中急性淋巴细胞白血病发病率比期望值高30倍。通过现有技术已发现急性白血病患者大多数有染色体异常。
A leukemia predisposing factor 1 Viral infection in human leukemia. Only adult T-cell leukemia (ATL) is definitely caused by a virus. Other types of leukemia other than ATL have not been confirmed to be infectious. 2 Genetic factors Leukemia patients do not directly pass on the disease to their offspring, but leukemia is clustered in certain families. The incidence of acute lymphoblastic leukemia is 30 times higher than expected in people with close relatives. It has been found through the prior art that most patients with acute leukemia have chromosomal abnormalities.
