加拿大某癌症研究中心通过10年的跟踪考察发现,每搬家一次,小孩患血癌的几率就增加30％。搬3次家的孩子罹患血癌的概率比没有搬家的孩子多60％;搬4次以上者,罹患率更高达90％。这可能与小孩的免疫能力无法适应新环境的新病毒有关。
A 10-year follow-up study by a Canadian cancer research center found that a child’s risk of having blood cancer increased by 30% for each move. Children who have moved 3 times have a 60% more chance of developing blood cancer than those who do not. If they move 4 times or more, the attack rate is as high as 90%. This may be related to children’s immune system can not adapt to the new environment of the new virus.
