Malignant lymphoma is a curable disease, so the two most important things that patients and their families need to figure out before treatment are: First, is the diagnosis reliable? It has been said that a good hand is ruined by a computer and a good pathologist is ruined by lymphoma. Do you know why? At present, there are not many hospitals that can make correct diagnosis of malignant lymphoma, and only a few hospitals in various provinces and cities have such strength in pathology department, and how many pathologists are specialized in lymphoma in these hospitals? The question is, have you correctly selected a professional pathologist in a competent hospital to make a correct pathological diagnosis of lymphoma for you? On the contrary, if not, how can your clinician make a treatment plan based on it, and will the result be good? However, according to my observation, quite a few patients and their families do not pay enough attention to this. Second, is the staging accurate? Staging is not only related to prognosis, but also closely related to the cycle of our chemotherapy. Therefore, it is necessary to make accurate staging after detailed and comprehensive examination, and then carry out treatment. But in clinical work it is often found that staging is very poor, because of saving money or anxious to do treatment? But do you understand: staging later than the actual, will cause over-treatment, resulting in unnecessary damage and waste of medical resources; staging earlier than the actual, under-treatment, lost the opportunity to cure or cause premature relapse. Now there are specialist doctors in tertiary hospitals all over the country, and it is much more convenient to see a doctor. More consultation before treatment, less regret after treatment.
