According to China Journal of Traditional Chinese Medicine, at present, the incidence of lymphoma in China is increasing year by year, and the age of onset is advanced, which is related to the following four reasons: First, environmental pollution, including excessive exposure to organic solvents such as hair dyes, living or working in newly renovated houses containing a lot of toxic and harmful chemicals, and frequent inhalation of automobile exhaust. Second, frequent exposure to all kinds of radiation. Third, the work pressure is great, because the incidence of lymphoma has a great relationship with human immune function. If people work under great pressure for a long time, it will lead to mental stress, great psychological pressure, irregular work and rest, which will make people very tired, reduce their physical resistance and induce lymphoma. The fourth is viral infection and bacterial infection. In addition, the early symptoms of lymphoma are very similar to colds, such as fever, sweating and cough, which are easily confused. Many people ignore the condition and delay the best treatment opportunity.
