In clinical practice, we often see some tumor patients who have relapsed and metastasized extensively after using all western medical treatments, and they ask for TCM treatment, taking TCM as the last straw. In fact, this is unrealistic and unscientific. TCM is not a panacea, and TCM does not bring every patient back to life like some false and exaggerated propaganda. However, if TCM can be used in the early stage of tumor treatment, it can effectively reduce the toxic side effects of radiotherapy, enhance its efficacy, strengthen the immunity of the body, effectively reduce the symptoms, improve the quality of life and prolong the survival period. Alternatively, long-term and intermittent use of TCM for consolidation and maintenance after completing a series of comprehensive treatment can be expected to achieve better efficacy and quality of life, and effectively delay or prevent tumor recurrence. Therefore, TCM treatment should be used throughout the whole process of tumor treatment. There is another clinical situation that some family members of tumor patients believe in some “partial prescriptions” or “ancestral secret recipes” that are falsely advertised by hearsay or the Internet or some institutions, so that patients can take them blindly and spend money unjustly and delay the best treatment time of the disease. The principle of TCM treatment is to identify the tumor. The principle of TCM treatment is to combine disease identification with evidence identification, tumor suppression with positive support, local treatment with systemic treatment, and somatic treatment with psychological treatment, etc., and to combine the treatment measures of Western medicine and the toxic side effects occurring in different treatment stages and treat them separately. The treatment of tumor in TCM must be comprehensive, flexible and different from person to person, and there is no unchanging “one-size-fits-all formula”.
