The cause of lymphoma is not known, but much evidence suggests an association with the following factors. Currently, it is believed that the three major causative factors leading to the occurrence of malignant tumors are genetics, lifestyle, and environmental factors. Adverse emotions and immune suppression Adverse emotions are the source of all evils, which can lower the body’s immunity and induce all tumors including lymphoma. Everyone will face various kinds of stress, but stress itself can not infringe on the body, but its own stress response to stress is the key. It is especially important to keep your body healthy and regulate your mind. In addition, staying up late for a long time can bring considerable damage to the body. Being under the influence of bad emotions for a long time can lead to a low immunity of the body. The occurrence of lymphoma is closely related to immunosuppression. Low immune function, such as AIDS, organ transplantation, long-term application of immunosuppressive drugs, certain rheumatic diseases, etc. are also related to the development of lymphoma. Environment The earth we live in now is heavily polluted and environmental toxins have brought more and more people closer to cancer. For the sake of our own health, everyone should start from being an environmental advocate and avoid being a user and manufacturer of various waste substances. Eat less packaged foods, such as cookies, cakes, and various snacks, most of which contain preservatives that are harmful to humans; use various cleaning agents carefully and try not to use hair dyes; and do not smoke, including second-hand smoke. Chemical carcinogens such as pesticides, hair dyes, benzene chemicals, etc., are also important causes. In the early years of the United States, it was reported that the incidence of lymphoma among Midwestern farmers was several times higher than that of the population due to the use of pesticides and pesticides; the incidence of lymphoma was also high among veterans of the United States Navy who had been engaged in painting ships and had been exposed to fluorine. The incidence of lymphoma is also higher among veterans of the U.S. Navy who were engaged in painting ships and those who were exposed to fluorine. The incidence of lymphoma is higher among atomic bomb victims, residents of Hiroshima who received more than 1 Gy of radiation and patients who were treated for spondylitis than in the general population. Infection There are three kinds of organic substances that make lymphoma possible, but of course, virus is only a factor in causing the disease, and it is not certain that you will get cancer if you have this virus. 1. E-B virus and adult T-cell leukemia lymphoma virus E-B virus is an extremely common member of the herpes virus family, the virus that causes infectious mononucleosis in young adults. In most cases, EBV infection, or mononucleosis, is not a serious condition, however, in patients who are immunocompromised, the virus can cause cellular carcinogenesis. HLTLV-1 is closely associated with T-cell lymphoma and has a high incidence in southern Shikoku and Kyushu, Japan. Four cases have been reported in China. 2, Helicobacter pylori Helicobacter pylori is a widespread infection that can lead to gastric inflammation, ulcers, and possibly gastric cancer. H. pylori is also associated with the development of gastric mucosa-associated lymphoma. Some authoritative organizations in the United States, such as the NCCN, have in recent years designated antibiotic therapy as the preferred approach for mucosa-associated lymphoma. This is an example of the application of antibiotics in the treatment of tumors. 3.HIV/AIDS The incidence of lymphoma in patients with HIV infection and AIDS is much higher than in the general population.
