Under normal circumstances a new closet does not cause leukemia. Leukemia is a class of malignant neoplastic diseases of the hematopoietic system, a malignant clonal disease associated with viral infection, abnormal immune function, radiation, chemicals, genetics and many other causes. Although chemicals are one of the causative factors of leukemia, a new closet containing only a small amount of benzene and formaldehyde is not an inevitable factor leading to leukemia. Leukemia is usually preceded by partial genetic mutations before the onset of the symptoms of leukemia, and a new wardrobe can only be a causative factor, but the probability of its own induced leukemia is generally not high. The occurrence of leukemia generally needs to experience two strikes, the first strike for genetic instability, more prone to mutation; the second is the mutation of key genes. Only after experiencing two strikes may leukemia be induced and the symptoms associated with leukemia appear. And only one closet emits formaldehyde and other harmful substances, which can only be counted as one blow. However, if once the fever, headache, vomiting, as well as liver and spleen lymph node enlargement and other symptoms similar to leukemia, it is recommended to go to the hospital in a timely manner, under the guidance of the doctor for blood routine and other related tests to rule out the occurrence of leukemia. In addition, for the newly bought closet can be taken to open windows and ventilation, put green plants, adsorption with activated carbon and other methods to reduce the damage caused by formaldehyde and other harmful substances to the human body. You can also ask professionals to test whether the indoor formaldehyde exceeds the standard, but also can take professional measures to remove formaldehyde, so as to avoid the occurrence of harmful to human health.
