At present, domestic and international studies have shown that although the real causes of this disease are not known, scientists have found that some risk factors are highly likely to induce the development of malignant lymphoma. 1, bacterial infection: certain subtypes of non-Hodgkin’s lymphoma, such as the occurrence of gastric mucosa-associated lymphoid tissue lymphoma is related to Helicobacter pylori infection, but the exact mechanism is not very clear, and most people believe that it is related to the combined effect of environmental, microbial and genetic factors. The application of antimicrobial therapy is effective, so the removal of H. pylori can prevent the occurrence of lymphoma associated with it. 2. Viral infection: Virus is the most important environmental pathogenic factor. For lymphoma, several tumor viruses are closely related to its occurrence, such as EBV, adult T-lymphotropic virus and human herpes virus. 3. Some autoimmune diseases increase the risk of lymphoma, such as dry syndrome, systemic lupus erythematosus, and hemolytic anemia. Therefore, prevention of some known risk factors may prevent the occurrence of such tumors. Chinese medicine treats the disease before it occurs. If all the above-mentioned hints of danger appear, you can go to a regular hospital and ask a real Chinese medicine practitioner to treat the disease with evidence, which will have good effect and may have a preventive effect. As a very important treatment tool, our country is vigorously promoting TCM, and western countries such as Europe and America have regained their awareness of the unique advantages of TCM in the last two years.
