In the current treatment of malignant tumors, the status and role of TCM are becoming more and more important. Colleagues in the western medical profession have also gradually understood and recognized the positive role played by Chinese medicine in the treatment of malignant tumors. Often patients come to outpatient clinics saying that after adjuvant chemotherapy or radiotherapy in so-and-so western hospital after surgery, western medical experts suggest to patients to go to Chinese hospitals to take oral Chinese medicine to consolidate the treatment. Tumor patients also tend to share their anti-cancer experience with each other and introduce the miracle of Chinese medicine against cancer. It can be said that in the whole process of malignant tumor treatment, Chinese medicine plays a role, and its efficacy is certain and tangible. There are different views and opinions between Chinese medicine and western medicine on the understanding of cancer. Western medicine advocates the application of means of “attacking evil” and “dispelling evil”, such as surgical resection, chemotherapeutic drugs and radiation to kill cancer cells, which are rapid and drastic in the treatment process and can effectively kill a large number of cancer cells, reduce the cancer load, and play a good near-term therapeutic effect. It can effectively kill a large number of cancer cells and reduce the cancer load, and has good near-term curative effect. However, it cannot solve the problem of distant recurrence and metastasis. It shows relative advantages in patients with early stage of cancer and good physique. On the other hand, Chinese medicine believes that malignant tumors are local manifestations of systemic diseases, and when treating them, we can see not only the “trees” (tumors), but also the “forest” (human body) and the “climate” (the natural and social environment in which a person lives). It is also necessary to see the influence of “climate” (the natural and social environment in which a person lives) on the “forest” and “trees”. Although Chinese medicine is inferior to Western medicine in “dispelling evils and attacking poisons”, its advantage lies in overall regulation – through adjusting the balance of yin and yang, internal organs and qi and blood of the organism, it can achieve the purpose of supporting positive qi and inhibiting cancerous tumors, and slowing down or even stopping the development of cancerous tumors, so as to make them live in peaceful coexistence with the organism, and this is how Chinese medicine is coexisting with the organism. This is the concept of “survival with tumor” in Chinese medicine. It is especially suitable for patients with malignant tumors in middle and late stages, as well as those who are too old and weak for surgery. Even for cancer patients who are under follow-up after surgery, radiotherapy and chemotherapy in the early and middle stages, it is also recommended to take Chinese medicine to prevent recurrence and metastasis. Recurrence and metastasis are the characteristics of malignant tumors, and most malignant tumors will recur and metastasize within a few years. Chinese medicine also believes that cancer is a local manifestation of systemic diseases. Although surgical resection and radiotherapy have killed local tumor tissues and cells, the dysfunction and disorder of the body’s internal environment still exists, i.e., the environment and soil pollution in which the cancer cells live still exists, and the “cancer toxin” has not been eliminated (modern medicine also believes that tiny cancer foci and cancer cells are not completely eliminated by surgery and radiotherapy). (modern medicine also believes that tiny cancer foci and cancer cells are difficult to be completely eliminated by surgery, radiotherapy and chemotherapy), leaving the hidden danger of distant recurrence and metastasis. Therefore, at this time, traditional Chinese medicine treatment is needed to restore the balance of yin and yang and the coordination of internal organs’ functions by supporting the positive and eliminating the evil, fine-tuning and balancing, so as to prevent and control the occurrence of cancerous tumors. This is also the embodiment of the idea of “treating the disease before it develops” in Chinese medicine – preventing the disease from changing and preventing the disease from recurring after it develops. In conclusion, the value and status of TCM in the prevention and treatment of malignant tumors should not be underestimated, and it will be more and more energetic and brilliant!
