The first problem: both normal people and leukemia patients should be aware of the importance of prevention! Especially leukemia patients, who do not think and discover the cause of the disease, but just keep on chemotherapy! And do not focus on active prevention, no matter how regular chemotherapy, the disease will recur. The second problem: the pathogenesis of leukemia: a radiation injury ionizing radiation leukemogenic effect has been confirmed, and the leukemogenic effect on humans is also prompted by the following facts: unprotected radiation workers, the incidence of leukemia is 8-9 times higher than the average doctor; patients with ankylosing spondylitis using radiation therapy, the incidence of leukemia is 10 times higher than the average person, Japan’s Hiroshima and After the atomic bombings of Hiroshima and Nagasaki in Japan, there was a 30-fold difference in the incidence of leukemia between the residents of the areas that were exposed to radiation and those that were not. Second, chemical factors Many chemicals are known to have leukemia-causing effects, decorating! Hair dye! The spontaneous leukemia of chickens, mice, cats, cattle and gibbons has been shown to be closely related to the role of viruses, and corresponding leukemia viruses have been isolated and shown to be retroviruses, but for a long time there has been no indication in humans that the blood of leukemia patients can infect healthy people and cause leukemia. In 1980, a new strain of virus (HTLV) was isolated from human T-cell leukemia, which is the same virus as the adult T-lymphocytic leukemia virus (ATLV) discovered in Japan in 1976. This is a new breakthrough in the study of the cause of human leukemia. So it is also important to prevent the virus. Third question: Think hard about what you can do to actively prevent and stay away from risk factors!
