So far, scientists have not found any obvious causative factors leading to childhood leukemia. However, it is widely believed in the medical community that environmental pollution should be an important causative factor for childhood leukemia, in addition to family inheritance. Back then, the significant increase in the number of local leukemia patients after the atomic bombing of Hiroshima, Japan, allowed scientists to link leukemia to environmental pollution. Recently, the medical profession alert eyes, gradually fall on the indoor environment pollution brought about by home renovation. There are indications that there is some mysterious link between indoor environmental pollution and the culprit of childhood leukemia. Zang Yan, chief pediatric surgeon at Beijing Children’s Hospital, found after six months of investigation that nearly 90 percent of the children she had seen with leukemia had recently been renovated, and many of them were “luxuriously decorated”. A statistics also shows that in a children’s hospital Institute of Hematology more than 1,800 children with leukemia admitted in 10 years, 46.7% of the children’s homes had been renovated within six months before the onset of the disease. “Renovation” is not only associated with children with leukemia. The survey showed that 54.6% of the more than 1,200 older leukemia patients in the last 10 years had also had their homes renovated within six months.
Although the home renovation will induce pediatric leukemia is still to be further proven, but a series of statistical data, so that medical experts have to make the following inference: decorative materials of harmful substances caused by indoor pollution, is likely to lead to the high incidence of childhood leukemia in recent years an important cause.
