γγThe gradual increase in the incidence of lymphoma and the advancement of the age of onset are related to the increased opportunities for viral and bacterial infections in modern man, increased environmental pollution, and excessive exposure to organic solvents and dyes. The occurrence of lymphoma is directly related to the malignancy of immune cells generated by lymphocyte proliferation and differentiation, such as EBV, human T-cell lymphoma/leukemia virus (HTLV-1), hepatitis virus, and Helicobacter pylori, which can directly or indirectly cause lymphocyte malignancy. Individuals who have undergone radiation therapy or are frequently exposed to radiation are also at high risk of developing this disease. In addition, the increase of environmental pollution, such as pollution of living environment, including car exhaust, residual harmful substances from home decoration, and some electronic waste discarded at random are also important causes. In addition, chemicals such as hair dyes and pesticides have also been confirmed to be related to this disease. These cancer-causing factors are almost ubiquitous in people’s lives, and it is almost impossible to completely prevent cancer-causing factors from invading the human body, so it is almost impossible to prevent lymphoma. The following methods may reduce the chance of lymphoma.γγ1.Receive more sunshine 2.Live regular 3.The amount don’t move in after the new house is decorated 4.Purchase a new car, conduct formaldehyde test and keep the window open for a longer time to ventilate
