Whenever the words “Lymphoma tendency”, “Suspected lymphoma”, “Lymphoma cannot be ruled out” appear in the diagnosis, the examination and diagnosis should be continued until the diagnosis is confirmed, and then chemotherapy or radiotherapy can be given. If the pathology is controversial, further examination and diagnosis should be conducted until the diagnosis is confirmed. If the pathology is controversial, further examination or consultation with a higher level medical unit may be performed. Experimental treatment is never allowed because anti-cancer drugs can shrink the nodes of lymphatic tuberculosis or lymphadenitis, and biopsies taken after chemotherapy are also unable to make a clear diagnosis due to atypical tissue structure or tissue necrosis, making future treatment difficult. Radiotherapy, as well as most chemotherapeutic drugs, have immunosuppressive effects and can contribute to the development of insidious infections. Both radiotherapy and chemotherapy have both immediate and long-term toxic effects and are strictly forbidden to be applied casually to patients without a clear diagnosis. Antimicrobial agents can also reduce the size of cancer with combined inflammation. Clinically, we often encounter that the tumor shrinks after the application of antimicrobial agents, and patients often do not seek further treatment, but after a period of time, the tumor increases rapidly again, and finally the diagnosis of lymphoma is made, but the disease is already at an advanced stage, and the best time for treatment is missed.
